Objective: To provide experience in using the buccal musculomucosal reversed flow arterial island flap in oral, nasal and orbital mucosal defects repair.
Methods: Six patients were operated by using the method. This flap supplied by the distal portion of the facial artery through the anterior buccal branches can be passed through the tunnel of the subcutaneous plane to repair the orbital mucosal defect or the nasal mucosal defect or septal perforation, or through the alveolar ridge cleft to close alveolar ridge cleft and oroantral fistula, or the cleft of the anterior hard palate or palatal fistula.
Results: The postoperative course was uneventful.
Conclusions: Flap was viable without the occurrence of hematomas, infections, parotid duct injury or obstruction, or facial nerve injury, or oral function loss.
