目的

探讨颌外动脉瓣修复口腔颌面部肿瘤术后组织缺损的可靠性，拟为临床工作提供指导。

方法

回顾2005 年6 月至2010 年6 月期间，颌面部肿瘤切除术后应用颌外动脉瓣进行颌面软组织重建的临床病例39 例，观察其近远期临床效果。

结果

本组39 例中37 例成活，2 例出现皮瓣远心端部分坏死，经修整换药后存活，术后随访1 ～6 年，无肿瘤复发或死亡病例，皮瓣功能及外观满意。

结论

颌外动脉瓣是一种很好的口腔颌面部肿瘤手术后软组织缺损的修复方法，具有血供足、静脉回流通畅、可靠性高、皮瓣存活率高、供区瘢痕隐蔽等优点，不需额外手术切口，皮瓣皮肤颜色、质地与受区匹配；但须术前排除颈部颌下淋巴结转移可能，并作好颌外动脉的血流评估。

Objective

To analysis the reliability of facial artery flap in repairing tissue defect after neoplasm ablation in oral and maxillofacial region.

Methods

The clinical outcomes of 39 tissue defect cases repaired by facial artery flap after oral and maxillofacial region in oral maxillofacial region from June 2005 to June 2010 were observed.

Results

Among 39 cases， the facial artery flap survived in 37 cases， but partial necrosis of the distal ledge of the flap healed after pruning and changing dressings in 2 patients.All patients were followed up for 1 year to 6 years.No cancer recurrence or death cases were reported.Both function and appearance were satisfactory.

Conclusions

Facial artery flap is a good reconstruction way for soft tissue defects after cancer ablation in oral and maxillofacial， because of sufficient blood supply， venous patency， high reliability， high flap survival rate， concealed area， no additional surgery incision，moderately good skin color and texture match.However， excluding cervical lymph node metastases and the facial artery assessment before surgery were necessary.
