Partial-thickness defects involving the vermilion and mucosa of the lip are difficult to repair surgically.
The purpose of this study was to evaluate the cosmetic and functional effectiveness of second-intention healing in the repair of partial-thickness defects confined predominantly to the vermilion and mucosa of the lip.
Thirteen patients with squamous cell carcinoma of the lip underwent Mohs micrographic surgery, which resulted in partial-thickness defects predominantly confined to the vermilion and/or mucosa of the lip. All defects were allowed to heal by secondary intention.
Twelve patients had good to excellent cosmetic results, and functional impairment was not noted in any of the patients. One patient whose defect extended to the cutaneous portion of the lip had deformation of the vermilion border.
Second-intention healing yields good to excellent cosmetic and functional results for the repair of partial-thickness defects involving the vermilion and/or mucosa of the lip. Defects involving more than 2 mm of the cutaneous lip or defects extending deeper than the superficial portion of the orbicularis oris muscle may result in cosmetic or functional deformity or both if allowed to heal secondarily.
累及唇部红唇和黏膜的部分厚度缺损手术修复困难。
本研究旨在评估二期愈合修复主要局限于唇部红唇和黏膜的部分厚度缺损的美容和功能效果。
13例唇部鳞状细胞癌患者接受了莫氏显微外科手术,术后形成主要局限于唇部红唇和/或黏膜的部分厚度缺损。所有缺损均采用二期愈合。
12例患者获得了良好至极佳的美容效果,且所有患者均未出现功能障碍。1例缺损延伸至唇部皮肤部分的患者出现了红唇缘变形。
二期愈合修复累及唇部红唇和/或黏膜的部分厚度缺损可获得良好至极佳的美容和功能效果。累及超过2mm唇部皮肤的缺损或延伸至口轮匝肌浅层以下的缺损若采用二期愈合可能导致美容或功能畸形或两者皆有。
