目的探讨股前外侧穿支血管皮瓣简称股前外侧皮瓣(anterolateral thigh flap,ATF),游离移植修复上颌骨切除后缺损的可行性及修复效果。方法回顾性分析18例上颌骨肿瘤患者的临床资料,上颌骨全切除术16例,上颌骨下部切除术2例。全部患者均用ATF I期修复。结果全部病例均移植成功,成功率100%,外形满意率为94%。恶性肿瘤17例,3年生存率为68.8%。结论 ATF可作为上颌骨切除术后修复材料,较好的恢复功能与外形。 Objective To investigate the feasibility and repair effect of anterolateral thigh flap (ATF), an anterolateral lateral femoral skin flap called free flap for repairing the defect after maxillary resection. Methods The clinical data of 18 patients with maxillary tumors were retrospectively analyzed. 16 cases of maxillary total resection and 2 cases of maxillary resection were performed. All patients were treated with ATF phase I repair. Results All the cases were successfully transplanted. The success rate was 100% and the satisfaction rate was 94%. 17 cases of malignant tumors, 3-year survival rate was 68.8%. Conclusion ATF can be used as a repair material after maxillary resection, which can restore function and appearance better.
