耳后皮下蒂皮瓣一期贯穿修复耳廓前部组织缺损

Postauricular Subcutaneous Pedicle Flap in One Stage Reconstruction of Retroauricula Defect

目的：观察耳后皮下蒂皮瓣一期修复耳廓前部组织缺损的效果。方法2011年9月至2013年9月，利用耳后皮下蒂皮瓣贯穿修复耳廓前部组织缺损16例，最小面积为1.0 cm×1.5 cm，最大面积为2.2 cm×2.5 cm，术后随访观察手术效果。结果术后耳后皮瓣均存活良好，随访2～12个月，耳廓外形满意，瘢痕不明显。结论耳后皮下蒂皮瓣血供可靠，形态、色泽、质地与周围正常组织一致，供瓣区隐蔽，是修复耳廓前部组织缺损的一种较好方法。

Objective To investigate the surgical efficacy of the postauricular subcutaneous pedicle flap in one stage reconstruction of retroauricula defect. Methods From September 2011 to September 2013, 16 cases with retroauricula defects were repaired by the postauricular subcutaneous pedicle flap in one stage reconstruction. The maximum size of defect was 2.2 cm×2.5 cm, and the minimum was 1.0 cm×1.5 cm. The surgical efficacy was observed after operation. Results All the postauricular flaps were survived postoperatively, and the auricular appearances of all the patients were satisfactory without visible scar during 2 to 12 months ’ follow up. Conclusion Postauricular subcutaneous pedicle flap, with reliable blood supply, similar contour, color, texture with surrounding tissue, and hidden donor site, is one of the best methods for the reconstruction of preauricular defects.
