Tapia's Syndrome after Cosmetic Malar Augmentation: a Case Report.

J Dent (Shiraz) 2019 Mar;20(1):66-69

Dept. of Oral and Maxillofacial Surgery, School of Dentistry, Shiraz University of Medical Sciences, Shiraz, Iran.

Tapia's syndrome is an infrequent complication of airway manipulation. It is usually due to an extra-cranial ipsilateral injury to the hypoglossal nerve and the recurrent laryngeal branch of the vagal nerve, which can happen after any surgery. It is usually characterized by unilateral paralysis of the muscle of the tongue and vocal cords although it can also occur bilaterally. We present a patient with postoperative unilateral hypoglossal and recurrent laryngeal nerves palsy that occurred after cosmetic malar augmentation for esthetic correction of the left cheek flatness with an uncomplicated transnasal intubation. We report the first case of Tapia's syndrome after porous polyethylene implantation for cosmetic cheek reconstruction. The patient was treated immediately after the diagnosis with 0.5mg dexamethasone for two weeks. After three months, the movements of the vocal cord and tongue movement started to improve and the patient's hoarseness fully recovered after six months.

Postoperative Pain Management after Impacted Third Molar Surgery with Preoperative Oral Lamotrigine, a Randomized, Double-blind, Placebo-Controlled Trial.

J Dent (Shiraz) 2018 Sep;19(3):189-196

Dept. of Oral and Maxillofacial Surgery, School of Dentistry, Shiraz University of Medical Sciences, Shiraz, Iran.

Statement Of The Problem: Extraction of the impacted third molar is often associated with severe postoperative pains, management of which are a big challenge. Lamotrigine is a new antiepileptic drug with pre-emptive analgesic properties, which is hypothesized to alleviate postoperative pain.

Purpose: This study aimed to evaluate the efficacy of pre-operative administration of single oral 200 mg lamotrigine in reducing the postoperative pain of impacted third molar surgery.

Materials And Method: In this randomized controlled trial, 100 adult patients were divided into two groups (n= 50) to receive either 200 mg oral lamotrigine or placebo 1 hour before the removal of impacted third molar. The patients were monitored for 4 hours in the recovery room and pain intensity was measured through visual analogue scale (VAS) for the next 12 hours at 30-minute intervals. The time and number of rescue analgesics used in 12 hours was also recorded.

Results: Two groups were not statistically significantly different regarding the severity of postoperative pain. (= 0.512).

Conclusion: Accordingly, pre-emptive administration of lamotrigine was not effective in diminishing the postoperative acute pain of impacted third molar extraction.

Efficacy and safety of premedication with single dose of oral pregabalin in children with dental anxiety: A randomized double-blind placebo-controlled crossover clinical trial.

Dent Res J (Isfahan) 2015 Nov-Dec;12(6):528-33

Department of Pediatric Dentistry, School of Dentistry, Kurdistan University of Medical Sciences, Sanandaj, Iran.

Background: Dental anxiety is a relatively frequent problem that can lead to more serious problems such as a child entering a vicious cycle as he/she becomes reluctant to accept the required dental treatments. The aim of this randomized double-blind clinical trial study was to evaluate the anxiolytic and sedative effect of pregabalin in children.

Materials And Methods: Twenty-five children were randomized to a double-blind placebo-controlled crossover clinical trial. Two visits were scheduled for each patient. At the first visit, 75 mg pregabalin or placebo was given randomly, and the alternative was administered at the next visit. Anxiolytic and sedative effects were measured using the visual analogue scale. The child's behavior was rated with the Frankl behavioral rating scale and the sedation level during the dental procedure was scored using the Ramsay sedation scale. The unpaired, two-tailed Student's t-test was used to compare the mean changes of visual analog scale (VAS) for anxiety in the pregabalin group with that of the placebo group. A repeated measures MANOVA model was used to detect differences in sedation level in the pregabalin and placebo groups regarding the interaction of 3-time measurements; sub-group analysis was performed using Student's t-test. The Mann-Whitney U-test was used to analyze the nonparametric data of the Frankl and Ramsay scales. A P < 0.05 was considered significant.

Results: The reduction of the VAS-anxiety score from 2 h post-dose was statistically significant in the pregabalin group. From 2 h to 4 h post-dose, the VAS-sedation score increased significantly in the pregabalin group. The child's behavior rating was not significantly different between the groups. The number of "successful" treatment visits was higher in the pregabalin group compared to the placebo group.

Conclusion: Significant anxiolytic and sedative effects can be anticipated 2 h after oral administration of pregabalin without serious side effects.

Comparing the Duration of Spinal Anesthesia Induced With Bupivacaine and a Bupivacaince-Lidocaine Combination in Trans-Urethral Resection of the Prostate (TURP).

Anesth Pain Med 2015 Aug 22;5(4):e25675. Epub 2015 Aug 22.

Student Research Committee, Namazi Hospital, Shiraz University of Medical Sciences, Shiraz, Iran.

Background: Spinal anesthesia is a safe anesthetic mode for transurethral prostate resection (TUPR). There are several studies assessing the effect of bupivacaine, lonely or accompanied by other drugs, on short duration operations. However, there is controversy regarding the exact combination.

Objectives: The aim of the study was to compare the effects of spinal anesthesia with bupivacaine and low dose lidocaine with bupivacaine alone on postoperative pain in those undergoing transurethral resection of prostate (TURP).

Materials And Methods: This was a randomized clinical trial performed in Shiraz university of medical sciences during one year. Eighty men scheduled for TURP were randomly assigned to receive spinal anesthesia with 1.5 mL bupivacaine 0.6% and 0.6 mL Lidocaine 1% or spinal anesthesia with 1.5 mL bupivacaine 0.5% in combination with 0.6 mL normal saline. The primary endpoint was the time lag between induction of spinal anesthesia and reaching the highest spinal block level. We also recorded the duration of spinal block declining to L1 level, operation duration and the admission duration.

Results: Both study groups were comparable regarding the baseline characteristics. We did not find any difference between the two study groups regarding the duration of anesthetic block reaching the maximum level (P = 0.433) and duration of decreasing it to L1 (P = 0.189). The course of postoperative recovery and duration of hospital admission were also comparable between the groups (P = 0.661).

Conclusions: Lidocaine does not have additive effects on duration and quality of spinal anesthesia with bupivacaine in those undergoing TURP.

Evaluation of a Single Dose Intravenous Paracetamol for Pain Relief After Maxillofacial Surgery: A Randomized Clinical Trial Study.

J Maxillofac Oral Surg 2014 Dec 6;13(4):478-82. Epub 2013 Aug 6.

Shiraz University of Medical Science, Shiraz, Iran.

Objective: The aim of this study was to evaluate, using a single dose of intravenous paracetamol, pain relief after maxillofacial surgery.

Materials And Methods: This is a controlled, randomized, uni- blind, clinical trial study to evaluate using a single dose of IV paracetamol for pain relief after maxillofacial surgery. The subjects were randomly divided into two groups with 40 subjects in each: group I received paracetamol (Apotel)* as a single dose and group II received placebo. Subjects were randomly allocated according to randomization lists. Paracetamol was used as a single dose (20 mg/kg in 100 cc of normal saline which was infused for 10 min after surgery in recovery room just before discharging). We used a visual analogue scale to investigate pain relief at various times.

Results: Analysis of the data, did not show any significant difference for age, sex and weight between the treatment group and the control group. Pain decreased 6 h after paracetamol infusion; then it increased mildly. In the control group, pain severity increased after operation, then it decreased mildly. Results showed a correlation between duration of surgery and pain severity in both the groups.

Conclusion: Paracetamol is effective on pain relief after maxillofacial surgeries. Operation time may be an important factor for induction of pain after the surgeries.

Orthognathic Surgery Patients (Maxillary Impaction and Setback plus Mandibular Advancement plus Genioplasty) Need More Intensive Care Unit (ICU) Admission after Surgery.

J Dent (Shiraz) 2015 Mar;16(1 Suppl):43-9

Postgraduate, Dept. of Craniomaxillofacial Surgery, School of Dentistry, Shiraz University of Medical Sciences, Shiraz, Iran;

Statement Of The Problem: Due to shortage of ICU beds in hospitals, knowing what kind of orthognathic surgery patients more need ICU care after surgery would be important for surgeons and hospitals to prevent unnecessary ICU bed reservation.

Purpose: The aim of the present study was to determine what kinds of orthognathic surgery patients would benefit more from ICU care after surgery.

Materials And Method: 210 patients who were admitted to Chamran Hospital, Shiraz, for bimaxillary orthognathic surgery (2008-2013) were reviewed based on whether they had been admitted to ICU or maxillofacial surgery ward. Operation time, sex, intraoperative Estimated Blood Loss (EBL), postoperative complications, ICU admission, and unwanted complications resulting from staying in ICU were assessed.

Results: Of 210 patients undergoing bimaxillary orthognathic surgery, 59 patients (28.1%) were postoperatively admitted to the ICU and 151 in the maxillofacial ward (71.9%). There was not statistically significant difference in age and sex between the two groups (p> 0.05). The groups were significantly different in terms of operation time (p< 0.001). Blood loss For ICU admitted patients was 600.00±293.621mL and for those who were hospitalized in the ward was 350.00±298.397 mL. Statistically significant differences were found between the two groups (p< 0.001). Moreover, there was a direct linear correlation between operation time and intraoperative estimated blood loss and this relationship was statistically significant (r=0.42, p< 0.001). Patients with maxillary impaction and setback plus mandibular advancement plus genioplasty were among the most ICU admitted patients (44%), while these patients were only 20% of all patients who were admitted to the ward. As a final point, the result illustrated that patients who were admitted to the ICU experienced more complication such as bleeding, postoperative nausea, and pain (p< 0.001).

Conclusion: Orthognathic surgery patients (maxillary impaction and setback plus mandibular advancement plus genioplasty) due to more intraoperative bleeding and postoperative nausea and pain would benefit from ICU admission after surgery.

Effect of tranexamic acid irrigation on perioperative blood loss during orthognathic surgery: a double-blind, randomized controlled clinical trial.

J Oral Maxillofac Surg 2015 Jan 1;73(1):129-33. Epub 2014 Aug 1.

Assistant Professor of Oral and Maxillofacial Surgery, Shahid Beheshti University of Medical Sciences, Shiraz, Iran. Electronic address:

Purpose: Perioperative hemorrhage is an important concern during orthognathic surgery. The purpose of this study was to assess the effect of tranexamic acid (TXA) irrigation on perioperative hemorrhage during orthognathic surgery.

Materials And Methods: In this double-blind, randomized controlled clinical trial, 56 participants who underwent orthognathic surgery were divided into 2 groups. The patients in the first group received TXA irrigation with normal saline (1 mg/mL), and the patients in the second group had normal saline for irrigation during orthognathic surgery. Age, gender, operation duration, the amount of irrigation solution used, and preoperative hemoglobin, hematocrit, and weight were the variables that were studied. The use of TXA solution for irrigation was the predictive factor of the study.

Results: Each group consisted of 28 patients. Group 1 consisted of 15 male patients (53.6%) and 13 female patients (46.4%) and group 2 consisted of 14 male patients (50%) and 14 female patients (50%). There was no difference in the distributions of the variables between the 2 groups, except for the duration of the operation. The mean duration of the operation was 3.94 ± 0.61 hours in group 1 and 4.17 ± 0.98 hours in group 2, and the difference in this respect between the 2 groups was statistically significant (P < .05). The mean intraoperative blood loss was 817.85 ± 261.83 mL in group 1 and 575.00 ± 286.90 mL in group 2 (P < .05). The mean volume of irrigation was 1,057.14 ± 407.04 mL in group 1 and 843.57 ± 275.48 mL in group 2 (P > .05).

Conclusions: TXA is effective in reducing intraoperative blood loss in patients for whom substantial blood loss is anticipated.

Does oral clonidine premedication decrease bleeding during open rhinoplasty?

J Craniofac Surg 2014 May;25(3):1101-3

From the *Department of Maxillofacial Surgery, Shahidbeheshti University of Medical Science, Tehran; †Department of Anesthesiology, Shiraz University of Medical Science, Shiraz; ‡Department of Maxillofacial Surgery, Shahidbeheshti University of Medical Sciences, Tehran; and §Department of Maxillofacial Surgery, Shiraz University of Medical Science, Shiraz, Iran.

This uni-blind randomized clinical trial study investigated the effect of clonidine premedication on preoperative blood loss during open rhinoplasty. The subjects were randomly divided into 2 groups. The members of the first group received oral clonidine as a single dose (0.2 mg) 2 hours before the induction of general anesthesia, whereas the members of the second group received a placebo. All subjects underwent open rhinoplasty without septoplasty. One anesthetic protocol was followed for all subjects. Variable factors include the subjects' weight, age, sex, and blood pressure during the surgery as well as blood loss during rhinoplasty. Group 1 consisted of 22 women and 11 men, whereas group 2 was composed of 16 women and 17 men. The mean for blood loss amounted to 68.03 ± 22.49 mL for group 1 and 132.12 ± 78.53 mL for group 2. An assessment demonstrated a significant difference in blood loss between the 2 groups (P < 0.001.) Oral clonidine premedication thus may decrease preoperative bleeding during open rhinoplasty.
