Uso do enxerto ósseo de parede anterior do seio maxilar para fechamento de fístula buco-sinusal.

Abstract

The oro-antral fistula (OAF) consists of a persistent communication between the maxillary sinus and the oral cavity, and it is a complication resulting from traumas, pathologies or dental extractions, occurring more frequently after the extraction of the superior molars due to their proximity to the maxillary sinus. Headache, maxillary sinusitis, pain, deglutition disorders and nocturnal cough are some of the reported signs and symptoms. The communication oro-antral smaller than 2mm of diameter, tend to close spontaneously, in the majority of cases without the need of a surgical approach. Cases of OAF larger than 3mm need surgical intervention. Surgical techniques which use flaps (palatine, vestibular or combined), bone graft and the pedicled buccal fat pad graft have been used for this purpose. This work aimed to describe a clinical case of OAF using the bone graft technique of the anterior sinus wall and discuss the advantages and limitations in relation to the most used techniques. The technique described is relatively simple, offering a satisfactory result, with minimum discomfort for the patient and reduced surgical time.
