Combined palatal flap and titanium mesh for oroantral fistula closure.

The oroantral fistula (OAF) is an epithelialized communication between the oral cavity and the maxillary sinus. In most of the cases, this communication occurs after molars and premolars extractions, but other factors may be cause of the communication, such as trauma. This article demonstrates an alternative surgical technique illustrated with a case report in which we perform the surgical treatment of OAF with palatal flap rotation combined with the use of titanium mesh in a victim of gunshot projectile wound in oral cavity.
