Evaluation of inner ear and hearing functions in lichen planus patients.

J Cosmet Dermatol 2021 Apr 2. Epub 2021 Apr 2.

Department of Dermatology, Harran University Faculty of Medicine, Sanliurfa, Turkey.

Background: Lichen planus (LP), which affects skin, nails, hair, and mucosal surfaces, is a chronic, autoimmune, and inflammatory disease, and autoimmune diseases may affect the inner ear.

Aims: This study aims to investigate hearing and inner ear functions of the LP patients.

Patients/methods: The present study was formed by 49 patients who were clinically and histopathologically diagnosed with LP and did not receive any treatment. The healthy group consisted of 52 healthy individuals. Pure tone audiometry (PTA) and distortion product otoacoustic emission tests were used in the hearing evaluation.

Results: At frequencies of 1, 2, 4, 6, and 8 kHz in the right ear and 0.5, 1, 2, 4, 6, and 8 kHz in the left ear in PTA, the lichen group's hearing thresholds were higher than the healthy group's. Upon comparing the hearing thresholds of LP patients with oral mucosa involvement and LP patients without oral mucosa involvement, there were significant differences between the groups at 1, 4, and 8 kHz in the right ear and at 0.25, 0.5, 2, 4, 6, and 8 kHz in the left ear.

Conclusion: Because of the increasing hearing thresholds, we think that hearing and inner ear functions of LP patients, particularly with oral mucosal involvement, are negatively affected.

Laparoscopic revisional surgery for failed anti-reflux procedures.

Ann Ital Chir 2021 Mar 2;10. Epub 2021 Mar 2.

Aim: Failure ratio of an anti-reflux surgery is 2-17% in adults. After unsuccessful fundoplications, if necessary, revisional surgeries can be performed. Revisional surgeries are technically difficult to perform and require professionally advanced experience. On the other hand, it is still controversial which technique should be used in revisional surgery. The aim of this study is to present our experience with revisional surgical procedures for complications or recurrences after anti-reflux surgeries.

Material And Metods: A total of 18 patients, 16 of whom were referred to our clinic from other centers, and who underwent revisional surgery for failed fundoplication between 2014 and 2019 were retrospectively analyzed RESULTS: Five patients were male and 13 were female. The mean age was 40.3±11.7 years. The most common symptom was the persistence of reflux symptoms (61.2%). Indications for revisional surgery were recurrent hiatal hernia in 10 patients, thightness in 4 patients, mesh migration in 2 patients, mesh migration with recurrent hiatal hernia in 1 patient, and mesh migration with thightness in 1 patient. The mean operative time was 107.2+29.2 minutes. The median hospital stay was 2.9 days (range: 1-6 days). The most common surgical procedure performed was the repair of hiatal crura with mesh, and reconstruction of fundoplication and fixation of neo-fundoplication to the right crus (44.4%). In addition, other surgical procedures performed were takedown of the previous fundoplication (16.6%), takedown of the previous fundoplication and reconstruction of fundoplication (11.1%), cruroplasty and fundoplication with gastric wedge resection (11.1%), removal of the mesh and takedown of the previous fundoplication (5.6%), removal of sutures from the hiatal crura (5.6%), and gastric wedge resection (5.6%). Four patients (27.8%) developed morbidity due to gastric perforation and pleural opening during these procedures. The median follow-up period was 29 months (range: 6-69 months). Two cases (11.1%) who underwent revisional surgery failed, and re-revisional surgery was performed.

Conclusions: Revisionary surgical procedures performed for failed anti-reflux surgery are not limited to re-fundoplication. Different procedures such as takedown of the previous fundoplication, reconstruction of fundoplication, removal of the mesh, removal of the sutures or wedge resection may be necessary. These procedures can successfully be performed laparoscopically by experienced surgeons in well-equipped centers.

Laparoscopic versus open complete meso-colic excision for right-sided colon cancer. Analysis of short-term outcomes.

Ann Ital Chir 2021 ;92:48-58

Scopo Dello Studio: L'emicolectomia destra per escissione mesocolica completa (EMC) laparoscopica mostrerebbe benefici comparabili a breve termine, nonché esiti patologici e oncologici per la chirurgia a cielo aperto. Lo scopo di questo studio era di confrontare la tecnica laparoscopica e la EMC aperta per i tumori del colon sul lato destro in termini di campioni patologici e risultati a breve termine.

Materiale E Metodi: I dati dei pazienti sottoposti a EMC laparoscopica (n=31) e EMC aperto (n=35) per adenocarcinoma del colon destro tra gennaio 2016 e giugno 2019 sono stati analizzati retrospettivamente. Sono stati confrontati dati demografici, parametri preoperatori, peroperatori e postoperatori e campioni di patologia dei due gruppi.

Risultati: Non ci sono state differenze statistiche tra il gruppo laparoscopico di EMC e il gruppo aperto di EMC in termini di età, sesso, indice di massa corporea, posizione del tumore, punteggio dell'American Society of Anesthesiologists (ASA), presenza di comorbidità, storia di altre neoplasie e precedente chirurgia addominale (p>0,05). I pazienti nel gruppo EMC laparoscopico presentavano lunghezze d'incisione più brevi, tempi operativi più lunghi, minore perdita di sangue operativa, tempi di mobilizzazione più brevi, recupero precoce del movimento intestinale, tempo più breve per dieta leggera, durata ridotta della degenza e dimensioni del tumore più piccole (p<0,05). Il numero medio di linfonodi raccolti in gruppi laparoscopici e di EMC aperti non era statisticamente significativo (29,83+8,90 e 31,34+13,10, rispettivamente). Non ci sono state differenze statistiche in termini di lunghezza del campione tra i gruppi laparoscopici e aperti di EMC (35,19+9,8 cm e 32,71+11,12 cm, rispettivamente). Il tasso di complicanze postoperatorie di 30 giorni era più elevato nel gruppo EMC aperto (35,5% contro 42,9%, rispettivamente), ma non statisticamente significativo (p>0,05).

Conclusioni: Patologici (lunghezze dei campioni, lunghezze dei margini di resezione, numero di linfonodi e resezione R0) e risultati a breve termine del gruppo laparoscopico di EMC erano comparabili. Inoltre, la EMC laparoscopica ha conferito benefici a breve termine in termini di lunghezze di incisione più brevi, minore perdita di sangue operativa, riduzione dei tempi di mobilizzazione, recupero precoce dei movimenti intestinali, minor tempo di dieta leggera e riduzione della durata della degenza ospedaliera. Sulla base di questi risultati, la EMC laparoscopica può essere considerata come un approccio elettivo di routine per il carcinoma del colon destro.

Evaluation of Bell's palsy in the cerebellopontine angle: An MRI study.

Int J Clin Pract 2021 May 7;75(5):e13971. Epub 2021 Jan 7.

Department of Otorhinolaryngology, Faculty of Medicine, Mersin University, Mersin, Turkey.

Background: Evaluation of cranial nerve morphology through measuring cross-sectional area (CSA) on magnetic resonance imaging (MRI) is increasing day-by-day in clinical diseases. In Bell's palsy (BP), the manifestation of the enlarged CSA of the facial nerve (FN) may be used for diagnosis. This study aims to evaluate whether there is an enlargement of the cisternal FN in BP.

Methods: This retrospective study included 43 patients diagnosed with BP. In the reconstructed MRI, the long (LD) and short (SD) diameters of the paralytic and normal sides of the FNs located in the cerebellopontine angle were measured, and the CSA was calculated using the Radinsky formula. Before the radiologic measurement, a preliminary experiment was carried out on the rat sciatic nerve to be able to determine the actual nerve boundary on MRI.

Findings: There was a statistically significant relationship between paralytic and normal sides in the measurements of LD, SD, and CSA. The paralytic side was larger than the normal side in the cisternal FN. According to the Receiver Operating Characteristic (ROC) curve, BP can be estimated with 60% sensitivity and 70% specificity by the CSA of the FN more than 1.04 mm . As a result of the preliminary experiment, it was found that the actual nerve boundary was at approximately 50% intensity between the minimum and maximum values.

Conclusion: Although entrapment of FN in the labyrinthine segment in BP was known, this study showed that the cisternal FN, which could be evaluated more conveniently, enlarged in the paralytic side compared with the normal side, and revealed the necessity of performing the comparison amongst the MRI studies on BP patients by a standardised measurement method. This study will also help clinicians to make a decision in the diagnosis of BP by giving a cut-off value for the CSA.

Evaluation of cochlear involvement and hearing function in lipoid proteinosis patients.

J Cosmet Dermatol 2020 Nov 11. Epub 2020 Nov 11.

Department of Otorhinolaryngology, Sanliurfa Training and Research Hospital, Sanliurfa, Turkey.

Background: Lipoid proteinosis (LP) is a rare genodermatosis involving amorphous hyaline accumulation in the skin, oral mucosa, larynx, mucous membranes, and viscera.

Aims: In this study, we aimed to investigate the effects of hyaline accumulation on cochlear function and hearing in LP patients.

Patients/methods: In this prospective study, 20 patients who were followed up with a diagnosis of LP between October 2016 and April 2020 in our clinic and 20 healthy individuals of the same age and gender, as a control group, were included. Pure-tone audiometry, tympanometry, and distortion-product otoacoustic emission tests of the patient and control groups were performed. The audiological results of the LP and control groups were compared statistically.

Results: In the comparison of air-conduction thresholds between groups in pure-tone audiometry, hearing thresholds in the patient group were found to be higher than the control group at frequencies of 250, 4000, 6000, and 8000 Hz for the right ear, and 500 and 4000 Hz for the left ear. In the comparison of signal-noise responses between groups in distortion-product otoacoustic emission (DP-OAE) test, signal-noise responses in the right and left ear at frequencies of 1000, 2000, 4000, and 6000 Hz were lower in the patient group than in the control group.

Conclusion: We found that the cochlear functions of patients with LP were affected due to the increase in hearing thresholds and decreased signal-noise responses. We think that LP patients are candidates for hearing loss in their later life.

Neutrophil-lymphocyte and platelet-lymphocyte ratios in otitis media with effusion in children: Diagnostic role and audiologic correlations.

Int J Clin Pract 2020 Oct 30:e13805. Epub 2020 Oct 30.

Department of Otorhinolaryngology, SBÜ Mehmet Akif İnan Training and Research Hospital, Sanliurfa, Turkey.

Aim: To investigate the relationship between hearing loss and complete blood count parameters including neutrophil, lymphocyte, platelet (PLT), mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in children with otitis media with effusion (OME).

Materials-method: The study group was formed by 244 paediatric patients who underwent ventilation tube placement because of OME, and was split into two groups as serous and mucoid. The control group included 112 individuals who have no hearing problems. Hearing levels were determined with pure tone audiometry in the study group, preoperatively, and control group. The blood parameters were compared between the serous, mucoid and control groups. The correlation analysis was performed between the blood parameters and hearing levels in the study group. The blood parameters were compared between the groups identified by hearing loss classification.

Findings: There were significant negative correlations between hearing levels and each of NLR, PLR and MPV. There were significant positive correlations between hearing levels and each of the lymphocyte and PLT. According to the receiver operating characteristic (ROC) curves, serous OME can be estimated with 68% sensitivity and 61% specificity by the NLR value more than 1.1, and 77% sensitivity and 77% specificity by the PLR value more than 102.4. The ROC curve revealed that slight hearing loss could be estimated with 70% sensitivity and 73% specificity by the NLR value more than 1.31, and 78% sensitivity and 77% specificity by the PLR value more than 102.4.

Conclusion: The present study revealed that NLR and PLR values were valuable parameters in the diagnosis of serous OME and predicting a hearing loss. These parameters may provide additional information to the audiogram that could influence the therapeutic decision.

Giant pedunculated colonic lipoma causing colo-colic intussusception in a patient with mechanical ileus.

Ann Ital Chir 2020 Mar 3;9. Epub 2020 Mar 3.

A giant colonic lipoma causing colo-colonic intussusception is extremely rare in adults. A 35-year-old woman visited our emergency room with abdominal pain, abdominal distension, nausea and vomiting. Physical examination showed a painful distended abdomen. Abdominal computed tomography revealed that there was a soft-tissue mass with a fat density of approximately 6 cm in diameter in the distal part of the transverse colon. Since the clinical presentation was that of a mechanical ileus, a laparotomy was performed. An intussusception was detected in the transvers colon. A soft and mobile mass was palpated in the transverse colon. Therefore, an extended right hemicolectomy with ileo-transversostomy was performed. Pathological examination revealed a giant pedunculated lipoma of 7 cm in diameter with no evidence of malignancy. Colonic lipomas are the third most common benign pathology seen in the colon. They are more common in women with a peak incidence between 50 and 60 years of age. The most common site of lipomas in the large bowel is the right hemicolon. Colonic lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain. Colonic lipoma causing colo-colic intussusception is extremely rare in the current literature. Surgical approach remains the treatment of choice for giant colonic lipomas. A colonic lipoma causing colo-colic intussusception should be considered in the differential diagnosis of mechanical bowel obstruction. The most important factor for establishing the diagnosis of intussusception caused by a colonic lipoma is awareness of the possibility, especially in adult patients with abdominal symptoms and episodes of intestinal obstruction.

Is There any Possible Role of Neurotrophin 3 in the Pathogenesis of Antrochoanal Polyp?

Medeni Med J 2020 28;35(1):40-46. Epub 2020 Feb 28.

Mersin University, Department of Otorhinolaryngology, Mersin, Turkey.

Objective: Antrochoanal polyp (ACP) is a benign soft tissue lesion arising from the inner wall of the maxillary sinus that extends into the nasal cavity and choana. Although it was first explained by Killian in 1906, the underlying pathogenesis has not been yet fully understood. Neurotrophins have been demonstrated to have a possible role in the pathogenesis of allergic rhinitis, idiopathic rhinitis and nasal polyps. To date any study has not investigated the function of neuronal inflammation and neurotrophins in the development of ACP. The objective of this study was to investigate the possible effect of neurotrophin-3 (NT-3) in ACP pathogenesis.

Method: Twenty adult patients with ACP who underwent endoscopic sinus surgery in our department were included in the study group. The control group included 15 patients with concha bullosa of middle concha who underwent lateral excisional surgery. Nasal tissue NT-3 staining scores were evaluated using immunohistochemical methods. Blood NT-3 levels of both groups were evaluated by enzyme-linked immunosorbent assay (ELISA).

Results: There were no statistically significant differences between these two groups regarding tissue NT-3 staining scores (p=0.843) and blood NT-3 levels (p=0.463). In addition, no statistically significant correlation has been observed between tissue NT-3 staining scores and blood NT-3 levels in both ACP (p=0.578) and control (p=0.359) group patients.

Conclusion: NT-3-related neuronal inflammation does not seem to have any role in ACP pathogenesis.

Prolapsed giant rectal gastrointestinal stromal tumor presented with incarceration A rare case of emergency rectal lesion.

Ann Ital Chir 2020 ;91:426-431

Prolapse of the tumor is an extremely rare clinical presentation in patients with rectal gastrointestinal stromal tumor (GIST). A 79-year-old male patient was consulted in the in-patient ward of internal medicine clinic of our hospital due to his incarcerated hemorrhagic mass protruding from the anal canal. Anal inspection revealed an incarcerated prolapsed hemorrhagic mass larger than 10 cm in diameter that looked like a cauliflower. The incarcerated rectal GIST protruding from the anal canal was removed by transanal excision under the emergency conditions. Clean surgical margins were obtained. No postoperative complications occurred. The histological diagnosis of high-risk GIST was made. Imatinib mesylate treatment was started postoperatively. The colorectum are the less common primary sites in adult GISTs (5%). Giant GISTs of the anorectum represent a real potential for anorectal emergency. They may be involved in rectal bleeding, obstruction, prolapse or incarceration. Prolapse of the tumor is an extremely rare clinical presentation in cases of rectal GISTs, and only a few cases have been reported in the medical literature so far. Complete surgical resection with en bloc excision of the tumor is the treatment of choice. Lower rectal GISTs are a rare entity that requires multidisciplinary management and long-term surveillance. We recommend, in case of lower rectal GIST, to perform an initial transanal local excision that achieves the essential R0 resection and define the risk of aggressive behavior and the involvement of the resection margins. Patients' close follow-up is mandatory to disclose as soon as possible local recurrences or metastases. Preoperative imatinib mesylate therapy and downstaging of the tumor may play an important role.

Primary mesenteric fibromatosis: A single Center experience.

Ann Ital Chir 2020 ;91:283-290

Aim: Primary mesenteric fibromatosis is a rare, locally invasive, non-metastasizing type of intra-abdominal fibromatoses with a very high rate of recurrence. In this study, we aimed to present our surgical approach, tumor characteristics, clinical presentation and long-term follow-up results in cases of primary mesenteric fibromatosis.

Material And Metods: The data collected from 11 patients who underwent surgery due to primary mesenteric fibromatosis in our clinic between 2010 and 2019 were analyzed retrospectively.

Results: Abdominal ipain, abdominal distention, and two patients (18.2%) were operated on with a diagnosis of acute abdomen in the emergency setting due to mechanical bowel obstruction in one patient There were 11 patients in our study. Six patients were female and 5 were male. The mean age was 44.2±15.8 years. Abdominal mass was detected in 5 patients (45.5%) who had complaints of mechanical bowel obstruction such as nausea and vomitingand gastrointestinal perforation in other patient. Mesenteric mass was detected in 3 patients (27.3%) with vague abdominal pain. One patient (9.1%) presented with abdominal pain and swelling of the right leg. After a mean follow-up period of 43.4±28.4 months, only 1 patient (9.1%) had recurrence and required reoperation approximately 80 months after the first operation. One patient (9.1%) died of anastomotic leakage and sepsis in the first 30 days postoperatively, and other patient (9.1%) idied of other reasons 1 year later postoperatively.

Conclusions: Although mesenteric fibromatosis is a benign tumor pathologically, the main principle in the treatment of this tumor which is clinically aggressive and has high recurrence rate is wide surgical resection. Mesenteric fibromatoses have a varied clinical presentation. Radiological imaging methods helps diagnosis and planning the surgical treatment. Immunohistochemical characteristics confirms the diagnosis and differentiates from other similar tumors.

Intractable external pancreatic fistula post-necrosectomy treated successfully with a fistulojejunostomy.

Ann Ital Chir 2020 Mar 9;9. Epub 2020 Mar 9.

Pancreatic fistula formation is a known complication of pancreatic surgery, pancreatitis, and pancreatic injury. We here report a case of a 65-year-old man who was diagnosed with gallstone-induced acute pancreatitis with walledoff pancreatic necrosis. The patient initially underwent medical treatment and percutaneous drainage at 4 weeks. After a four-week period, a formal laparotomy with necrosectomy, and the catheter drainage of the cavity were performed. Having postoperatively developed a pancreatic fistula, the patient was managed conservatively. After 6 weeks of medical treatment, patient underwent an endoscopic retrograde pancreatography and was diagnosed with disconnected duct syndrome. The conservative management was continued for 3 more months. Pancreatic duct stenting was attempted but was not successful in cannulating the disconnected duct, and he was finally planned for a Roux-en-Y fistulojejnuostomy. The fistulojejunostomy was performed on an average of 6 months after placement of peri-pancreatic drain. The patient recovered uneventfully and is doing well at a 12-month follow-up. Refractory external pancreatic fistula is defined as an external pancreatic fistula not resolving with these measures for longer than 6 weeks. Most fistulas developing after acute pancreatitis are related directly to the need for necrosectomy to treat infected necrosis. Patients are initially approached conservatively. When patients fail to respond to either percutaneous drainage, endoscopic interventions, or novel techniques, operative intervention is the most viable approach to treat the fistula. Fistulojejunostomy is a safe and effective treatment for intractable pancreatic fistula having the benefit of avoiding a difficult major pancreatic resectional surgery, along with low postoperative morbidity and mortality.

Quantitative Analysis of the Vascular and Neural Compartments of the Jugular Foramen in Dry Skulls.

Turk Neurosurg 2020 ;30(6):832-840

Mersin University, Faculty of Medicine, Department of Neurosurgery, Mersin, Turkey.

Aim: To compare the right and left sides and the endo?exocranial orifices of the jugular foramen (JF) considering the vascular compartment (VC) and the neural compartment (NC).

Material And Methods: A total of 20 human dry skulls belonging to the inventory of Medical Faculty, Department of Anatomy, were included in this study. Numerical values were obtained using direct anatomical and also computed tomography measurements.

Results: The endocranial and exocranial VC occupied wider areas on the right side than on the left side (p < 0.05). However, there was no statistically significant difference between the surface area of the endocranial and exocranial NC in terms of the sides (p > 0.05). The length of the endocranial VC was greater on the right than on the left side. The right exocranial VC was wider than the left exocranial VC. However, the widths and lengths of the endocranial and exocranial NC showed no statistically significant difference between the sides (p > 0.05).

Conclusion: The right-sided dominance of JF observed in this study was attributed to the length of endocranial VC and the width of exocranial VC.

Growth dynamic of the geniculate ganglion in children: a retrospective computed tomography study.

Surg Radiol Anat 2020 Mar 25;42(3):307-314. Epub 2019 Nov 25.

Department of Otorhinolaryngology, Mersin University Faculty of Medicine, Mersin, Turkey.

Purpose: The main aim of this retrospective computed tomography (CT) study was to examine the morphometric development of the geniculate ganglion (GG) in children aged between 1 and 18 years for surgical approaches.

Methods: This study was placed on 41 patients (20 females and 21 males) including cochlear implantation cases aged from one to 18 (at mean, 6.44 ± 5.79) years. All the measurements belonging to the length, width and area of GG were performed with a CT scanner.

Results: The morphometric values of GG were not different in terms of sex or side, statistically (p > 0.05). The length (p = 0.155) of GG was not correlated with the increasing ages from one to 18 years; however, its area (p < 0.001) and width (p = 0.003) were found to be increased in the childhood period. Linear functions for the length, width and area of GG were calculated as y = 2.028 + 0.011 × age (years), y = 1.496 + 0.014 × age (years), and y = 3.239 + 0.035 × Age (years), respectively. The dehiscence of GG was found in 22 (26.8%) out of 82 temporal bones.

Conclusion: Our data suggested that the area and width of GG were progressively increasing with age in the childhood period. The calculated formula representing the growth dynamic of GG in children and the incidence of the presence of the dehiscent GG can be useful for radiologists and otologists to estimate its size and to avoid iatrogenic injury during early childhood surgeries.

Radioanatomic Assessment of the Geniculate Ganglion Dehiscence and Dimension: A Cadaveric Study.

World Neurosurg 2020 Feb 13;134:e913-e919. Epub 2019 Nov 13.

Mersin University Faculty of Medicine, Department of Otorhinolaryngology, Mersin, Turkey.

Objective: The main aim of this study placed on cadavers was to compare the data related to geniculate ganglion (GG) dehiscence and dimension obtained from computed tomography (CT) with dissection values.

Methods: This study was conducted on 20 temporal bones obtained from 10 cadavers (4 female, 6 male) aged between 45 and 92 (71.50 ± 15.98) years. All the measurements related to GG dimension were performed with a CT scanner and microdissection.

Results: The size of GG including its area, length, and width did not show statistically significant differences in terms of sex, side, and assessment method (CT and cadaveric dissections). The dehiscent GG was observed in 6 (30%) and 5 (25%) out of 20 temporal bones in CT and cadaveric dissections, respectively. The presence and absence of GG dehiscence in CT and dissection were similar in 75%.

Conclusions: Our findings based on dissection data suggest that radiologic evaluation of dehiscent GG detection might be erroneous by 25%, which highlights that surgeons should be careful when lifting the dura to prevent GG injury during middle cranial fossa surgical approaches. On the other hand, there was no statistical difference between CT and dissection measurements related to GG dimension.

Morphometric Assessment of the Carotid Foramen for Lateral Surgical Approach.

J Int Adv Otol 2019 Aug;15(2):222-228

Department of Otorhinolaryngology, Mersin University School of Medicine, Mersin, Turkey.

Objectives: This study aimed to compare the right and left sides of the carotid foramen (CF) to determine its precise location according to certain anatomical landmarks.

Materials And Methods: Twenty human dry skulls were included in the study. A digital caliper and a digital image analysis software were used to obtain direct anatomical numerical values. Then, the same parameters on dry skulls were assessed with computed tomography (CT).

Results: CF was found to be round shaped (62.5%), oval shaped (32.5%), and tear-drop shaped (5%). In all cases, the position of CF was seen as just postero-laterally of the foramen lacerum. According to the jugular foramen, CF was seen to be anterior in 85% and antero-medial in 15% of the cases. Regarding the morphometric values of the surface area, the length and width of CF were observed to be 37.86±11.24 mm2, 8.02±1.09 mm, and 6.86±0.90 mm at direct anatomical measurements and 39.69±10.07 mm2, 7.89±1.14 mm, and 6.41±0.90 mm at CT, respectively. The angles between the supramastoid crest-CF-zygoma root and the supramastoid crest-CF-mastoid process were determined as 37.11±6.87º and 42.22±6.40º at direct anatomical measurements and 36.59±4.94º and 43.71±4.55º at CT, respectively.

Conclusion: A significant difference in sides was not observed in relation with the numerical data of CF obtained from CT or from direct anatomical measurements of dry skulls. Moreover, a significant difference was not found between radiological and direct anatomical measurements. Therefore, precise radiological assessment of this region by an experienced neuroradiologist may be assumed as a fundamental need for successful surgeries of the skull base, in addition to thorough anatomical knowledge of neurootologists and neurosurgeons.

Evaluation of the Foramen Magnum Area Calculated by Different Methods: A Radioanatomic Study.

J Craniofac Surg 2019 Oct;30(7):e665-e667

Department of Otorhinolaryngology.

Purpose: The main objective of the study was to evaluate the probable diversity in the area of the foramen magnum (FM) calculated by different measuring methods.

Methods: The study was conducted on 24 dry skulls, present in the collection of the Anatomy Department, Faculty of Medicine, Mersin University. The area of FM was calculated by different measurement methods including automatic field setting, Teixeria and Radinsky formulas obtained from anatomic (ASM), photographic (PSM) and radiologic (RSM) skull measurements.

Results: The areas of FMs calculated by Teixeria formula in RSM, PSM, and ASM were as follows: 857.96 ± 99.97 mm, 796.68 ± 105.08 mm, and 820.86 ± 96.40 mm, respectively. The areas calculated by Radinsky formula in RSM, PSM, and ASM were as follows: 851.37 ± 99.68 mm, 792.63 ± 104.18 mm, and 814.85 ± 94.99 mm, respectively. Lastly, the areas calculated by the automatic field setting of RSM and PSM software were as follows: 799.75 ± 103.38 mm and 752.83 ± 105.60 mm, respectively.

Conclusion: Statistical significance was observed between the areas of FM obtained from RSM, ASM, and PSM when calculated by the automatic field setting, Teixeria formula, and Radinsky formula. The authors think that considering the amorphous shape of FM, the automatic field setting of the software should be used to obtain the most accurate numerical data related to the area of FM.

Morphometric properties of the facial canal in children: A retrospective computed tomography study.

Int J Pediatr Otorhinolaryngol 2019 Sep 29;124:59-67. Epub 2019 May 29.

Mersin University Faculty of Medicine, Department of Otorhinolaryngology, Mersin, Turkey.

Purpose: The main objective of the study was to examine the morphometric development of the facial canal in temporal bones aged from one to 18 years for pediatric otosurgeons and neurosurgeons.

Methods: The study was performed on 41 patients including cochlear implantation cases (20 females and 21 males) with a mean age of 6.44 ± 5.79 years. All the measurements belonging to the facial canal including the length, width and angles of its segments were performed using the data of computed tomography assessment.

Results: The numerical data of the facial canal segments were not different in terms of sexes or sides, statistically (p > 0.05). The width of the labyrinthine segment (p = 0.145), the length of the tympanic segment (p = 0.555), the first (p = 0.067) and second (p = 0.060) genu angles seemed to reach adult size at two years of age. In addition, the length of the labyrinthine segment (p = 0.064) and the width of the mastoid segment (p = 0.264) seemed to attain adult size at four years, while the width of the meatal foramen (p = 0.264) seemed to arrive adult size at seven years. However, the length of the mastoid segment and the width of the tympanic segment were developing independently of increasing age between 1 and 18 years.

Conclusion: Our data suggested that, contrary to the general acceptance in the literature, the dimension of the facial canal segments show remarkable changes during the transition from intrauterine life to adult life. The regression equations representing the facial canal growth dynamic in children may be useful for otosurgeons to estimate the size of its segments and to prevent iatrogenic injury during early childhood surgeries such as cochlear implantation.

False-Positive Laryngeal FDG Uptake During PET/CT Imaging: Reinke's Edema.

Turk Arch Otorhinolaryngol 2018 Jun 1;56(2):114-116. Epub 2018 Jun 1.

Department of Otorhinolaryngology, Mersin University School of Medicine, Mersin, Turkey.

Positron emission tomography/computed tomography (PET/CT) is frequently used for diagnosing, staging, and following-up various malignancy types because it provides information on the site and metabolic activity of the tumor. Fluorodeoxyglucose (FDG) uptake by the normal laryngeal tissue is symmetric and low, whereas that under some non-malignant conditions of the larynx, such as vocal cord paralysis and Teflon granuloma, is asymmetrically increased. We reported the first case of histologically proven Reinke's edema causing false-positive laryngeal FDG uptake on PET/CT imaging. A clinician must be aware of these rare benign lesions in the case of increased FDG uptake, and histopathological investigation is mandatory to rule out malignancy for suspicious cases.

Does stapes surgery improve tinnitus in patients with otosclerosis?

Braz J Otorhinolaryngol 2017 Sep - Oct;83(5):568-573. Epub 2016 Aug 2.

University of Mersin, Faculty of Medicine, Department of Otorhinolaryngology, Mersin, Turkey.

Introduction: Otosclerosis (OS) is the primary disease of the human temporal bone characterized by conductive hearing loss and tinnitus. The exact pathogenesis of tinnitus in otosclerosis patients is not known and factors affecting the tinnitus outcome in otosclerosis patients are still controversial.

Objectives: To find the effect of stapedotomy on tinnitus for otosclerosis patients.

Methods: Fifty-six otosclerosis patients with preoperative tinnitus were enrolled to the study. Pure tone average Air-Bone Gap values, preoperative tinnitus pitch, Air-Bone Gap closure at tinnitus frequencies were evaluated for their effect on the postoperative outcome.

Results: Low pitch tinnitus had more favorable outcome compared to high pitch tinnitus (p=0.002). Postoperative average pure tone thresholds Air-Bone Gap values were not related to the postoperative tinnitus (p=0.213). There was no statistically significant difference between postoperative Air-Bone Gap closure at tinnitus frequency and improvement of high pitch tinnitus (p=0.427). There was a statistically significant difference between Air-Bone Gap improvement in tinnitus frequency and low pitch tinnitus recovery (p=0.026).

Conclusion: Low pitch tinnitus is more likely to be resolved after stapedotomy for patients with otosclerosis. High pitch tinnitus may not resolve even after closure of the Air-Bone Gap at tinnitus frequencies.

An Unusual Cause of Dysphagia: Live Leech in the Tongue Base.

Turk Arch Otorhinolaryngol 2015 Dec 1;53(4):192-194. Epub 2015 Dec 1.

Department of Otorhinolaryngology, Mersin University Faculty of Medicine, Mersin, Turkey.

Inhaled or ingested foreign bodies are relatively common causes of airway obstructions. They can be associated with significant morbidity and even mortality. Although various foreign bodies are aspirated or ingested, live leeches are rarely encountered. We reported a case of a live leech at the base of the tongue in an 18-year-old female patient with a history of unfiltered spring water drinking. We discussed the surgical technique and importance of anesthesia with this brief study.

Are new generations getting bigger in size? Anthropometric measurements in erzurum.

Eurasian J Med 2014 Oct;46(3):192-7

Department of Pediatrics, Ataturk University Faculty of Medicine, Erzurum, Turkey.

Objective: When the dimensional measurements of the students who spend most of their time at school are taken into consideration, inappropriate dimensions of school equipment may affect their body and psychological improvements negatively. Anthropometric measurements are necessary for designing the educational equipment of the children at school. It is emphasized that anthropometric measurements of the people living in different climate and altitude conditions will be different. It is mentioned that anthropometric data available for a certain region will be able to change as a result of changing socio-economical conditions and therefore, anthropometric data update is necessary at certain periods.

Materials And Methods: In 2000 anthropometric data obtained from the children between the age of seven and fifteen, who were in sitting and standing positions, were measured with a repeated measurement in the same schools in 2007.

Results: Mean values of the heights of elbow at standing position of the female students, 8 years old, increased from 72.38 cm in 2000 to 74.67 cm in 2007 (p<0.001). Most of the other measurements in 2007 were larger than those in 2000, giving the impression that new generation children are getting larger in size.

Conclusion: As reported in the literature, anthropometric data should be updated at certain period of times.

The effect of plasmakinetic cautery on wound healing and complications in mastectomy.

J Breast Cancer 2013 Jun 28;16(2):198-201. Epub 2013 Jun 28.

Department of General Surgery, Ankara Oncology Training and Education Hospital, Ankara, Turkey.

Purpose: Surgical equipment used in breast cancer surgery that affects wound healing and minimizes complications seems to be a popular investigation topic. The aim of this study is to evaluate the effect of plasmakinetic cautery on wound healing in patients receiving mastectomy.

Methods: Forty-six consecutive breast cancer patients receiving modified radical mastectomy were evaluated prospectively. Plasmakinetic cautery was used in 24 operations and electrocautery was used in 22 operations in random order to manage skin flaps and excise breast tissue. In the postoperative period, vacuum drainage amount and duration time as well as the start time of arm exercises were recorded. Complications like seroma, surgical site infection, hematoma, and flap necrosis were determined.

Results: Age, body mass index, breast volume and flap area parameters were similar in each group. Mean drainage duration was found to be 5.5 days in the plasmacautery group and 7.9 days in the electrocautery group (p=0.020). In the plasmacautery and electrocautery groups, mean drainage volume was 707 and 1,093 mL, respectively (p=0.025). There was no statistical significance between the groups when operation duration, amount of blood loss, time to start arm exercises, seroma, hematoma, surgical site infection, and flap necrosis were considered.

Conclusion: Plasmakinetic cautery is a promising new surgical instrument that provides atraumatic, scalpel-like cutting precision and electrosurgical-like hemostasis, resulting in minimal tissue injury. So, plasmacautery shortens the drainage amount and duration time compared to electrocautery without elongating operation duration or increasing the amount of blood loss.
