RESUMO
Introduction: Orthognathic treatment has assumed an important role in orthodontics and maxillofacial surgery in the last years; however, little has been investigated about this type of treatment. Objectives: The main purpose of this study was to identify major factors and/or predictors associated with postoperative pain (PP) and hospital length of stay (LOS) after orthognathic surgery. Materials and methods: 52 patients who underwent orthognathic surgery from 2008 to 2010 at the University Hospital of São Paulo University were investigated. Study variables such as patient characteristics, preoperative, intraoperative and postoperative data were collected. The outcome variables were PP and LOS. Descriptive and analytical statistics was computed for all variables. Results: 27.6% of patients had pain in the postoperative period. Lidocaine used in general anesthesia was an associated factor of PP. The overall mean LOS was 2 days; gender, location of procedure, type and duration of anesthesia were identified as probable predisposing factors. There was a significant correlation between anesthesia time and discharge. Anesthesia variables were more predictably related with postoperative pain and hospitalization time. Location of orthognathic procedure, however, was an important surgical variable that influenced in LOS. Conclusions: Intravenous lidocaine boluses used during general anesthesia were associated with PP. Male patients, single-jaw surgery, inhalational anesthesia and duration of anesthesia were predisposing factors that improve LOS.
Introducción: la cirurgía ortognática ha asumido un papel importante en la ortodoncia y en la cirugía maxilofacial en los últimos años. Sin embargo, se ha investigado poco sobre este tipo de tratamiento. Objetivos: el objetivo principal de este estudio fue identificar los principales factores o predictores asociados con el dolor posoperatorio (DP) y el tiempo de internación (TI) después de la cirugía ortognática. Materiales y métodos: fueron estudiados 52 pacientes que se sometieron a cirugía ortognática (2008 - 2010) en el Hospital Universitario de la Universidad de São Paulo. Se recolectaron variables de estudio tales como características de los pacientes y datos perioperatorios. Estadística descriptiva y analítica se calculó para todas las variables. Resultados: el 27,6% de los pacientes presentaron dolor en el posoperatorio. La lidocaína utilizada en la anestesia general fue un factor asociado del DP. El TI medio global fue de 2 días. El género, la localización del procedimiento, el tipo y la duración de la anestesia se identificaron como factores predisponentes probables. Hubo una correlación significativa entre el tiempo de anestesia y de descarga. Las variables de anestesia podían predecirse más cuando estaban relacionadas con el DP y el TI. La localización de la cirurgía ortognática, sin embargo, fue una variable quirúrgico importante que influyó en lo TI. Conclusiones: la lidocaína intravenosa en bolo utilizada durante la anestesia general se asoció con el DP. Los pacientes varones, la cirugía sobre una sola mandíbula, la anestesia inhalatoria y la duración de la anestesia fueron factores predisponentes que prolongaron el TI.

HumanosRESUMO
Lipoma of the tongue is an uncommon benign tumor, being even more rare when there are multiple lesions. Lipoma accounts for 1-5% of all oral neoplasms. Lipoma occurs predominantly in males over the age of forty, although, in rare cases, children can be affected. Here, we report an unusual case of a female patient with bilateral lingual lipomas that were treated through surgical excision.
RESUMO
Sialolithiasis is a disease that affects the salivary glands. It is characterized by the presence of calcified structures within the duct system or within the glandular parenchyma. Those calculi, or sialoliths, can obstruct normal salivary flow, potentially leading to infectious sialadenitis, with pain, local swelling, and purulent discharge. Treatment typically consists of the surgical removal of the calculus, often in conjunction with sialoadenectomy. The authors report an atypical case of bilateral submandibular gland sialolithiasis treated conservatively, using intra-oral access to remove the calculi.
RESUMO
The Internet has been used in oral surgery teaching mainly to deliver learning material across the World Wide Web and to make use of online interactivity resources in everyday surgical practice, such as by e-mails, discussion groups, and chats. The aim of this paper is to describe and evaluate a Web-based practical course on oral surgery principles, which was applied to undergraduate students. This course was investigated as a distance learning simulation in which the student would be performing surgical activities at home, and the teacher and the school environment would be absent. A Web site was created containing the course material. For this study, the students participated in the Web-based course in a multimedia lab equipped with computers and Internet, internal sound system and TV circuits. In the event of significant mistakes by students, the TV circuit could be used to show the correct procedure for all the participants at the same time. Microcameras were used to monitor the student's actions during the Internet use. Students' impressions were determined by a questionnaire. Computer manipulation with ease and antiergonomic postures were observed. We concluded that distance learning courses with practical modules must be considered as a special type of educational modality, with reference to the relationship between the student and the computer.
