[摘要] 股前外侧皮瓣作为口腔颌面部软组织缺损的修复皮瓣，近年来已得到临床医生的广泛应用，但其血管的解剖变异往往会给手术造成困难，甚至取皮瓣失败。本文报道1例因股前外侧皮瓣血管解剖变异而术中紧急采用股前内侧皮瓣替代股前外侧皮瓣修复颌面部贯通缺损的病例，并结合文献探讨股前内侧皮瓣的解剖及应用。

    [Abstract] Anterolateral thigh flap is perfect for reconstructing maxillofacial soft tissue defects. This tissue has been widely used by clinicians， but often causes operation difficulties because of vascular variation. In this paper， we report a case where anteromedial thigh was used as new donor site when the vascular anatomic variation of anterolateral thigh perforator flap induced a failure in the flap harvest. Moreover， this paper discusses the anatomy and application of anteromedial thigh flap.
