A Case of Large Oroantral Fistula Repair Using Iliac Bone Plug / 대한이비인후과학회지

An oroantral fistula causes chronic sinusitis, whose signs and symptoms include facial pain, swelling, tenderness and nasal and oral discharge. The clinical diagnosis of oroantral fistula canbe confirmed by radiographic findings, and treated surgically by antrostomy alone or in combination with Caldwell-Luc's operation. The fistula is then repaired with mucosal flap or bone plug. We experienced one case of chronic sinusitis caused by oroantral fistula that was repaired with mucosal flaps (buccal and palatal region) with bone plug (taken from ilium) and produced good results. So we report it with the review of the literature.
