摘　　要：目的设计以旋股外侧动脉降支为蒂的股部皮肤穿支血管的嵌合皮瓣，为修复口腔颌面部的大面积、复杂的洞穿性缺损提供一种新的方法。方法根据旋股外侧动脉降支的走行及分支、其在股部正面及两侧可能存在的皮肤穿支血管，设计以旋股外侧动脉降支为蒂的穿支嵌合皮瓣修复口腔颌面部软组织缺损8例。此种皮瓣可分为3种类型：股前外侧皮瓣＋股前内侧皮瓣、股前外侧皮瓣＋股直肌穿支皮瓣、股前外侧皮瓣＋股前外侧皮瓣。结果术后8例16块皮瓣均成活，无并发症，且供区均直接拉拢缝合，未行皮片移植。术后随访1—9个月，患者面部外形和功能均良好，供区畸形和功能障碍均不明显。结论以旋股外侧动脉降支为血管蒂的穿支嵌合皮瓣吻合血管数量少，较切取2个皮瓣供区损伤小，组织量大，适合口腔颌面部大型复杂的组织缺损的修复。Objective To report the application of the chimeric perforator flap pedicled with descending branch of lateral circumflex femoral artery for large and complicated oromaxillary soft tissue defect. Methods Based on the anatomic study of descending branches and cutaneous perforators of lateral circumflex femoral artery, the perforator vessels were found and used as flap pedicle. The perforator flap was made as chimeric flap for repairing the oromaxillary soft tissue defect in 8 cases. The chimeric perforator flaps were divided into three types as anterolateral thigh flaps and anteromedial thigh flaps, anterolateral thigh flaps and rectus femoris perforator flaps, and anterolateral thigh flaps and anterolateral thigh flaps. Results All the 16 flaps in 8 cases survived completely with no complication. The wounds in donor sites were all primarily closed with no skin graft. The patients were followed up for 1 - 9 months with good functional and esthetic results. There was no morbidity in donor sites. Conclusions The chimeric perforator flap has a large tissue volume for large and complicated oromaxillary defect. There is no need for extra donor site and extra blood vessel anastomasis.
