Resumo:
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.
