RESUMO
The present study aimed to establish the profile of patients who underwent orthognathic surgery in a private clinic by evaluating their demographic characteristics, their facial types, and aspects related to the surgical procedures that were performed. The sample consisted of 419 medical records from male and female patients aged 15 to 62 years who underwent orthognathic surgery between 2001 and 2011. A single examiner collected data by evaluating a database of information extracted from medical records, particularly radiographic and photographic analyses. The following criteria were evaluated: gender, age, skin color, type of orthognathic surgery, type of associated temporomandibular joint (TMJ) surgery, complications, and recurrences. Seventeen patients were rejected because they had incomplete records. The average age of the patients was 28.5 years old; most were females (255 patients) and faioderm (295 patients). The most prevalent facial pattern was Pattern III (n = 166, 41.3%). Orthognathic surgery that affected the maxilla, jaw, and chin was the most prevalent type (n = 199, 49.5% of cases). A genioplasty was performed concurrently with combined surgeries and single-jaw surgery in 76.86% of patients (n = 309). TMJ surgery was performed concomitantly with orthognathic surgery in 4% of cases (n = 16). The most common postoperative complication was infection/inflammation (n = 12). We concluded that there was a higher frequency of orthognathic surgery among women and young people, the brunette skin phenotype was prevalent, and most patients had a combination of maxillary and mandibular problems.

Objetivo: A proposição do presente trabalho foi analisar a frequência relativa dos vários tipos histológicos de cistos e tumores odontogênicos benignos. Metodologia: por meio do estudo retrospectivo de prontuários dos pacientes submetidos a tratamento no Hospital Santo Antônio - obras Sociais Irmã Dulce, Salvador-BA, Brasil, sob anestesia geral, durante o período de 2004-2010. Foram avaliados: idade, gênero, tipo histológico, sítio anatômico, tratamento realizado e recorrência. Resultados: observaram-se 34 pacientes do gênero feminino e 24 do gênero masculino. o ameloblastoma (43%) foi o tipo histológico mais frequente, seguido do tumor odontogênico ceratocístico (26%), mixoma odontogênico (10%) e odontoma (9%). entre os cistos, o maior percentual foi de cisto paradentário (60%). A média de idade foi de 28,1 anos. A principal localização anatômica foi a mandíbula em região posterior.
Purpose: The purpose of this study was to analyze the relative frequency of the various histologic types of odontogenic cysts and tumors. Methodology: A retrospective study was conducted based on the medical records of patients undergoing treatment at Hospital Santo Antônio - obras Sociais Irmã Dulce, Salvador-BA, Brazil, under general anesthesia during the period 2004-2010. Age, gender, histological type, anatomic site, treatment performed and recurrence were evaluated. Results: The study comprised 58 patients (34 females and 24 males). Ameloblastoma (43%) was the most common histological type, followed by the keratocystic odontogenic tumor (26%), odontogenic myxoma (10%) and odontoma (9%). Among the cysts, the paradental cyst showed the highest percentage (60%). The mean age was 28.1 years. The main anatomical location was the posterior region of the mandible.
RESUMO
PURPOSE: The aim of this study was to determine the thickness of the parietal bone in bone graft donor sites and to study the relationship between parietal bone thickness and gender or cephalic index. MATERIALS AND METHODS: We studied 300 parietal bones from 150 human skulls (84 male and 66 female) from individuals aged 18 to 60 years at the time of death. On each parietal bone, 9 areas were drawn by use of reference anatomic landmarks (bregma, lambda, asterion, and pterion), and bone thickness was determined in the areas adjoining the sagittal suture--superior-anterior (Sa), superior-medial (Sm), and superior-posterior (Sp). RESULTS: Mean thickness measurements ranged from 2.30 to 11.25 mm in the Sa area, from 3.08 to 13.32 mm in the Sm area, and from 2.88 to 12.26 in the Sp area. Smaller mean measurements were observed in the Sa area, with the smallest mean thickness being found in brachycephalic female specimens. The largest mean thickness was also found in female specimens in the Sm area. Statistically significant differences between genders were found only in the Sa area in dolichocephalic and mesocephalic specimens. CONCLUSION: Although the best bone graft donor site surgically is different in individuals of different genders and with different cephalic indexes, our findings suggest that harvesting from the anterosuperior area of the parietal bone should not be performed.
