Abstract:

The lateral femoral circumflex artery system perforator flaps include anterolateral thigh perforator flap supplied by the lateral descending branch and oblique branch of lateral femoral circumflex artery，anteromedial thigh perforator flap supplied by the medial descending branch of lateral femoral circumflex artery，and tensor fascia lata perforator flap by the ascending branch of lateral femoral circumflex artery. The advantages of these flaps include the low donor site morbidity， the convenient donor site，the good vascular quality，the large soft tissue volume，the ability to be harvested as a chimeric flap with multiple various tissue components，and being far from the head and neck region which is fit for two-team approach. The lateral femoral circumflex artery system perforator flaps can be flexibly chosen according to the different defects，so as to obtain the best effect in oral and maxillofacial reconstruction.

Key words: anterolateral thigh perforator flap, anteromedial thigh perforator flap, tensor fascia lata perforator flap, oral and maxillofacial defect, reconstruction

摘要：

旋股外侧动脉系统穿支皮瓣主要包括以旋股外侧动脉外侧降支和斜支为源动脉的股前外侧穿支皮瓣、以旋股外侧动脉内侧降支为源动脉的股前内侧穿支皮瓣和以旋股外侧动脉升支为源动脉的阔筋膜张肌穿支皮瓣，具有供区隐蔽而并发症少、血管质量好、可切取组织量多、能够制备成携带多种组织的嵌合皮瓣、术区远离头颈部适合两组同时手术等优点，在口腔颌面部缺损的修复重建中可根据缺损的不同情况灵活选用，以获得最佳效果。
