An Unusual Case of Cholesterol Granuloma of the Jaws

JM. An Unusual Case of Cholesterol Granuloma of the Jaws. EC Dental Science 2017 July;12(2): 83-. 86.

EC Dental Science

Cholesterol granuloma is a granulation tissue tumor caused by foreign body reaction to the deposition and inadequate drainage of cholesterol crystals. This pathology shows an erosive and expansive growth. It is rare to find it in the maxillofacial area, but it has been reported appearing in maxillary sinuses and rarely within the jaws. We report a rare case of a cholesterol granuloma in the jaw of a 31-year-old woman.

Congenital heterotopic gastrointestinal cyst of the oral cavity: report of rare case.

Br J Oral Maxillofac Surg 2016 10 1;54(8):969-970. Epub 2016 Feb 1.

Dental School, Universidad del Zulia, Maracaibo, Venezuela.

Gastrointestinal heterotopic cyst is a rare benign lesion diagnosed mainly in young boys, but it can also occur in adults.1 It is possible that ectopic islands of endodermal cells infiltrate the primitive stomodeum during the fourth week of embryonic development, and cause multidirectional differentiation.2 Heterotopic gastric mucosa can appear almost anywhere in the gastrointestinal tract, but mostly in the mediastinum, retroperitoneum, and oral cavity, where it can be found on the tongue, floor of the mouth, and lips.

Combination of transconjunctival and lateral canthotomy with modified endaural approaches in midface osteogenic distraction.

Br J Oral Maxillofac Surg 2016 07 3;54(6):707-9. Epub 2015 Dec 3.

Senior Resident, Oral and Maxillofacial Surgery Residency Program at Universidad El Bosque, Bogotá, Colombia.

Distraction osteogenesis is widely used in the treatment of craniofacial deformities when external or internal distraction devices are placed after the corresponding osteotomies. The external system is most common as it is possible to adjust it to correct the distraction vectors. Internal devices, however, are better accepted by patients, as they minimise the psychosocial impact.

Modification of Blair Approach With a Modified Endaural Component to Access the Parotid Region.

J Craniofac Surg 2015 Sep;26(6):1972-4

*Oral and Maxillofacial Surgery Residency Program at Universidad El Bosque, Oral and Maxillofacial Surgery Department at Clínica El Bosque, Cranio-Maxillofacial Surgery Department at Hospital Simón Bolívar †Department of Oral and Maxillofacial Surgery and Publications Committee at Universidad El Bosque ‡Department of Oral and Maxillofacial Surgery, Universidad El Bosque, Bogotá, Colombia.

Objective: The aim of this study is to present our experience with a modification of the Blair approach to the parotid area, by means of a modified endaural component, which provides both excellent exposure and optimal functional and esthetic results, mainly over the preauricular area.

Patients And Methods: A retrospective case series study was performed. It included surgical cases of patients who were operated on the parotid region in which the mentioned approach was indicated. The information was collected from the database available at the Universidad El Bosque Oral and Maxillofacial Surgery Department in Bogota, Colombia from 2008 to 2013.

Results: The sample consisted of 12 patients, with ages ranging from 23 to 56 years and a mean age of 38 years. A total of 8 patients were women and 4 patients were men. Parotid pathologies included salivary gland tumor (10 patients) and cranial base tumor (2 patients). Procedures executed were: superficial lobe and total parotidectomy resection, pharynx extended and cranial base tumor resections.

Conclusions: This investigation presents our experience with a modified approach to the parotid region. This approach gives an extended and safe exposure to the region with excellent cosmetic outcomes.

Mandibular Symphyseal L-Inverted Midline Osteotomy to Correct Mild Laterognathia and Malocclusion.

J Craniofac Surg 2015 Jul;26(5):1709-11

*Department of Oral and Maxillofacial Surgery, Hogar Clínica San Rafael, Maracaibo †Oral Surgery Program, Universidad del Zulia ‡Department of Oral and Maxillofacial Surgery, Hospital Manuel Noriega Trigo, San Francisco §Department of Oral and Maxillofacial ||Department of Plastic, Maxillofacial and Reconstructive Surgery Department Hospital Universitario de Maracaibo ¶Department of Oncology Surgery, Hospital Universitario de Maracaibo #Department of Oral and Maxillofacial, Hospital General Dr. Adolfo D'Empaire, Cabimas **Oral Surgery Program, Universidad del Zulia ††Department of Oral and Maxillofacial Surgery, Hogar Clínica San Rafael, Maracaibo, Venezuela ‡‡Department of Oral and Maxillofacial Surgery §§Publications Committee, Universidad El Bosque, Bogotá, Colombia.

Objective: The aim of this study was to present the authors' experience with a new surgical technique to correct mild laterognathia and malocclusion by means of an L-inverted midline osteotomy.

Patient And Methods: The patient was a 26-year-old woman diagnosed with left laterognathia and ipsilateral posterior crossbite. She was operated by using this novel technique in November 2009 at Hogar Clínica San Rafael, Maracaibo, Venezuela. Bicortical midline symphyseal vertical osteotomy was executed, followed by block removal of the central right inferior incisor and its surrounding alveolar bone. The mandibular segmentation was completed by means of a right hemimentoplasty. After this, a 4-mm right mandibular rotation was made, and titanium plates and monocortical screws of the 2.0 system were used to achieve the rigid fixation.

Results: The patient showed outstanding aesthetic and functional results after 5 years.

Conclusions: This technique provides a new treatment option for the correction of mild laterognathia cases associated with dental malocclusion.

Conversion of aneurysmal bone cyst into fibrous dysplasia: A rare pediatric case report

DOI: 10.1007/s12663-016-0899-1

Journal of Maxillofacial and Oral Surgery

Aneurysmal bone cyst (ABC) is an uncommon, non-neoplastic, expansive and erosive bone lesion. Considered as a pseudocyst due the lack of epithelial lining, the presence of giant cells and similarity to other lesions can difficult preoperative diagnosis; biopsy findings must be co-related to complete clinical and radiological assessment. ABC´s controversial etiopathogenesis and variable clinicopathological presentations have been widely described, but to date, there are just a few reports in literature describing the development of fibrous dysplasia (FD) from an ABC, and even less cases occurring in the jaws. We describe the case of an ABC in a 8 year-old male patient, affecting the body of the mandible, which showed accelerated growth associated to thinning of the buccal, lingual and lower cortical plates. The treatment consisted of repetitive surgical resection, curettage of the lesion and mandibular reinforcement with osteosynthesis reconstruction plates. A 16-month follow-up showed self-limitation of the overgrowth. The final histopathological and radiological analysis confirmed the FD diagnosis.

Razones para la extracción de piezas de dentales en la Facultad de Odontología, Universidad de Costa Rica

Odovtos Int J Dent Sc 2011;13:36-41

Odovtos - International Journal of Dental Sciences

Dental caries and periodontal disease are described as the main etiologic factors for tooth loss worldwide. This is the first epidemiologic study evaluating the reasons for tooth extraction in Costa Rica. Objectives: to determine the main reasons and to report the patterns for tooth extraction in the population under study. Materials and methods: all patients who where attended at the School of Dentistry at the University of Costa Rica between the years 2007 and the 2009 and that had the required information in their personal files were included. Each tooth extraction was classified in one of eight categories according to the reason for extraction and variables such as dental piece, sex and age of the patient were analyzed. Results: Women represented 52% of the total 2618 tooth extractions included. The average age was 36, 29±16,1. Dental caries was the main reason in 50% of the cases, periodontal disease in 17.8% and third molars in 17%. Women had their teeth extracted for elective treatments more than men, whereas men’s extractions were more related with disease reasons. For subjects over 50 years of age, periodontal disease became the main reason for extraction. Conclusion: Efforts directed at reducing the rate of dental extractions by disease must focus on further educating the Costa Rican population on dental caries and periodontal disease, and future studies should monitor the effect of these interventions through time.
