面动脉逆行岛状颊肌粘膜瓣的临床应用

目的：探讨应用面动脉逆行岛状颊肌粘膜瓣修复口腔、鼻腔和眶区粘膜缺损的可行性。方法：对6例口、鼻腔和眶区粘膜缺损患者应用面动脉逆行岛状颊肌粘膜瓣修复。该瓣是以面动脉的远心端为血管蒂，通过前颊支和颊肌表面及其内部的血管网供血，在动脉周围包绕适量的软组织以利静脉回流，可通过皮下隧道转移到眶区或鼻腔，通过牙槽嵴裂隙转移到腭部。结果：6例患者术后肌粘膜瓣完全成活，效果满意，无血肿、感染、腮腺导管损伤、面神经损伤和开口功能障碍等。结论：面动脉逆行岛状颊肌粘膜瓣血运好，转移灵活，可以解决常规方法难以修复的口腔前部、鼻腔、眶区粘膜缺损。

The buccal musculomucosal reversed flow arterial island flap: clinical application

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
