Abstract
目的 探讨中、重度全层唇缺损的修复方法.方法在缺损一侧或两侧(若缺损较大,一侧唇瓣不够用时)设计以唇动脉为蒂的唇瓣向缺损区推进转移修复全层唇缺损.若缺损较大,单纯用缺损两侧口唇组织仍不足以修复时,可将一侧唇瓣向外侧延伸绕过口角至另一侧上或下唇(根据缺损是在下唇或上唇),形成包括上下唇组织在内的大型唇瓣向缺损区推进修复缺损.若缺损为单纯的红唇缺损,唇瓣切口应沿唇弓设计.结果临床应用于67例,其中上唇38例,下唇29例.缺损最大水平宽度3.5 cm,最小1.6 cm.单纯红唇瓣20例,红白唇瓣47例.单侧唇瓣10例,双侧57例.所有唇瓣均全部存活,伤口Ⅰ期愈合,修复后的口唇丰满,外形满意.结论唇动脉血管恒定,唇瓣血供可靠,本法不仅能用于单纯红唇缺损的修复,还可广泛用于红、白唇同时缺损的修复,因是用同类组织修复,且组织量丰富,故术后能完全恢复口唇所特有的红、白唇结构及功能,是修复中、重度全层唇缺损的理想方法。
