Treatment of an oroantral fistula with chronic sinusitis: a case report.

A patient with an oroantral fistula of seventeen years' duration presented clinically complaining of symptoms suggesting recurring episodes of acute maxillary sinusitis. After control of the acute sinusitis, the defect was repaired using a buccal flap procedure and the sinus was enucleated via a Caldwell-Luc approach. The sinus contents included what appeared to be a chicken bone. The patient healed uneventfully. A discussion of the management of chronic oroantral fistulas and a case report are presented.
