内眦动脉穿支为蒂的角形皮瓣在中面部重建中的应用

Application of horn shaped flap pedicled with the angular artery perforator for midface reconstruction

目的探讨内眦动脉穿支为蒂的角形皮瓣在中面部重建中的应用效果。方法2014年3月至2017年4月，对20例中面部因外伤或体表肿瘤、黑痣、瘢痕等切除术后的软组织缺损，设计以内眦动脉穿支为蒂的角形皮瓣，皮瓣最大宽度等于缺损宽度，长度约为缺损长度的2.5～3.0倍，旋转加推进覆盖缺损区进行修复。结果 20例患者切口均一期愈合，角形皮瓣全部成活良好，随访1个月至1年，皮瓣颜色、光泽、质地与邻近皮肤相同。结论内眦动脉穿支为蒂的角形皮瓣修复中面部软组织缺损，术后血运可靠，切口愈合后无明显瘢痕，供区可直接拉拢缝合，是修复中面部缺损的一种较好的方法。

Objective To evaluate the effect of the horn shaped flap pedicled with the angular artery perforator for midface reconstruction.Methods From March 2014 to April 2017, twenty patients underwent operations for the reconstruction of midface defect, defect due to trauma, tumors, moles, scar and other soft tissue defects after resection. Various horn shaped flap pedicled with the angular artery perforator, perforator flap was rotated and pushed to repair the defect area.The maximum width of the perforator flap was equal to the width of the defect, and the length is about 2.5 to 3.0 times the length of the defect.Results All flaps survived.After 1 month to 1 year follow up on 20 cases, the flap is significantly improved in color、shape and function.The patients were satisfied with the final aesthetic and functional results.Conclusions The flap has flexibility and simply with reliable blood supply.The donor sites could be closed directly without skin graft.it is a simple and fast method for the reconstruction of midface defect.
