Prevalência de comunicação buco sinusal em exodontias de terceiros molares superiores realizadas na liga acadêmica de cirurgia da Universidade Federal de Campina Grande.

Abstract

Surgical removal of the third molars is one of the most routine minor oral surgery procedures in the clinic. Most third molar surgeries are performed uneventfully. However, such procedure may cause serious complications to the patient, such as the continuity solution of the maxillary sinus forming a sinus buccal communication. Sinus buccal communication (CBS) is an open connection between the oral cavity and the maxillary sinus. The aim of this study was to evaluate the prevalence of oral sinus communications in upper third molar surgeries performed by the Academic League of Surgery of the Federal University of Campina Grande. The universe consisted of all medical records of patients treated by the Academic League of Surgery and submitted to upper third molar extraction from April 2018 to August 2019 at the Federal University of Campina Grande, Patos, Paraíba. Of the 249 medical records evaluated, (71.9%) were female, with an average age of (25.92) years, with caries disease (24.8%) being the main indication factor for extraction. The most used image exam for evaluation of the dental element was the panoramic radiography (95.9%). In Winter's classification both dental elements 18 and 28 were most commonly upright (74.4% and 65.9% respectively). The most commonly used preoperative medications were corticosteroids (44.1%) and postoperative medications were analgesics associated with anti-inflammatory drugs (58.5%) and no statistically significant association was found between sinus or oral communication ( 0.8%), sex (p = 0.484), age (p = 0.416) and extracted teeth (p = 0.737). CBS is a rare complication associated with removal of the upper third molars.
