Common flap techniques for reconstructing large defects in the lower lip are often destructive and complex and result in unsatisfactory function and appearance. This article describes a modified technique that uses sliding labial tissue flaps to avoid these problems.
Eight patients with lower lip carcinomas had defects ranging from one third to four fifths of the length of the lower lip after tumor resection. The defects were closed with sliding labial tissue flaps, taking advantage of the elasticity of soft tissue to reduce the loss of normal tissue. Patients were followed for 2 to 12 years.
The functional and cosmetic results were good, and there were no intra- or postoperative complications. Some patients experienced tightness of the lower lip that disappeared within 6 months. Carcinoma did not recur in any patient after a median follow-up period of more than 5 years.
This modified labial tissue sliding flap technique is simple, safe, functionally and aesthetically satisfactory, sacrifices little healthy tissue, heals rapidly, and requires no further revision. The technique is effective for repairing defects covering one third to four fifths of the lower lip.
用于重建下唇大缺损的常见皮瓣技术通常具有破坏性且复杂，会导致功能和外观不尽人意。本文介绍一种改良技术，该技术使用滑动唇组织瓣来避免这些问题。
8例下唇癌患者在肿瘤切除后下唇缺损长度占下唇长度的三分之一至五分之四。利用软组织的弹性，采用滑动唇组织瓣闭合缺损，以减少正常组织的丢失。对患者进行了2至12年的随访。
功能和美观效果良好，术中及术后均无并发症。部分患者下唇出现紧绷感，6个月内消失。中位随访期超过5年后，所有患者均未复发癌症。
这种改良的唇组织滑动瓣技术简单、安全，在功能和美学上令人满意，牺牲的健康组织少，愈合快，无需进一步修复。该技术对于修复占下唇三分之一至五分之四的缺损有效。
