应用矩形皮瓣法修复先天性隐耳畸形

目的 探讨应用矩形皮瓣法修复先天性隐耳畸形的可行性.方法 2001至2004年,对9例共15侧行矩形皮瓣法隐耳整复术,其中双侧6例,单侧3例.将患耳的上半部从头皮中牵出,参照:Hyakusoku矩形皮瓣法,在耳廓上后方设计由2个三角形皮瓣和1个矩形皮瓣组成的"三瓣"(故也可称为三瓣法).按设计切口切开皮肤,游离皮瓣,对耳横肌、耳斜肌的短缩切开分离松解,并切开松解耳上肌纤维组织,最后转移皮瓣,缝合皮肤.结果 所有皮瓣均未出现血运障碍,手术切口愈合良好.随访3个月至2年,患耳功能和外形均较满意.结论 矩形皮瓣法适用于轻、中度隐耳畸形,可给患耳上后部提供足够的皮肤组织,颅耳沟成形好,供区损伤轻.

Correction of cryptotia with the square skin flap

OBJECTIVE: To investigate the feasibility of square skin flap for the correction of cryptotia. METHODS: From 2001 to 2004, 9 cases (15 sides) with cryptotia were treated with square skin flaps. The upper part of the auricle was distracted from behind the scalp. Based on the Hyakusoku square flap method, 2 triangle flaps and one square flap were designed on the upper part behind the auricle. The flaps were elevated and auricular muscles were released. Then the flaps were transferred. RESULTS: All the flaps survived completely with good wound healing. The patients were followed up for 3 months to 2 years with satisfactory aesthetic and functional results. CONCLUSIONS: The square flap is suitable for mild and moderate cryptotia, which provides enough tissue for reconstruction of auriculocephalic sulcus. The method is easily performed with good result and minor donor stie morbidity.
