目的探讨游离股前外侧皮瓣在修复上颌窦术后缺损中的应用。方法采用游离股前外侧皮瓣游离移植,同期修复上颌窦术后缺损17例。结果 17例患者中,2例患者出现血管危象,1例皮瓣部分坏死,5例出现早期局部并发症。术后随访3个月至4年,10例术后头颈部外形及功能基本恢复正常,受区和供区均无严重并发症;2例带瘤生存;5例分别因局部复发、颈淋巴结转移及远处转移而死亡。结论利用吻合血管的游离股前外侧皮瓣,更易于塑形修复,并减少供区并发症的发生,是修复各种头颈肿瘤术后洞穿性缺损的良好方法。

Objective To explore the clinical application of free anterolateral flaps in reconstruction of postoperative defects of maxillary sinus.Methods The postoperative defects of maxillary sinus were reconstructed using free anterolateral flaps in 17 cases.Results Among the 17 cases,2 cases occurred vascula crises,1 case occurred flap necrosis,5 cases had early local complications.After 3 months to 4 years follow-up,the appearance and functions on the head and heck area turned to be normal in 10 cases.No severe complication occurred in both donor and recipient site.2 patients survived with tumor and 7 patients died of local recurrence,cervical lymphatic metastasis and distant metastasis.Conclusion Anterolateral flap is easy to shape and has less complications of donor site.It is useful in the reconstruction of postoperative defects of head and neck tumor.
