This study examined the reliability and cosmetic outcome of a Z-transposition flap with mucosal advancement for repairing partial thickness defects of the lower lip measuring less than 50% the lower lip length.
Eleven patients treated in 2003 and 2004 were prospectively evaluated. All patients had undergone Moh's tumor excision and were referred for reconstruction. All defects measured less than 50% the lower lip length. Wound healing problems, cosmetic outcome, and flap reliability were evaluated at greater than 3 months postoperatively.
All patients healed uneventfully with good cosmetic results and flap reliability.
The Z-transposition flap is an acceptable alternative for reconstructing partial thickness defects of the lower lip.
本研究探讨采用带黏膜推进的Z形移位皮瓣修复下唇部分厚度缺损（缺损长度小于下唇长度的50%）的可靠性及美容效果。
对2003年和2004年治疗的11例患者进行前瞻性评估。所有患者均接受了莫氏肿瘤切除术，并被转诊进行重建手术。所有缺损长度均小于下唇长度的50%。术后3个月以上评估伤口愈合问题、美容效果和皮瓣可靠性。
所有患者均顺利愈合，美容效果良好，皮瓣可靠性高。
Z形移位皮瓣是修复下唇部分厚度缺损的一种可接受的替代方法。
