遵循几何原理的改良下三角瓣法修复单侧唇裂的临床研究

目的由于单侧唇裂传统方法手术效果不稳定，故应予以改进，提出遵循几何原理的改良下三角瓣法。方法通过几何原理。分析唇裂设计中鼻小柱基部与患侧鼻翼基部的定点变化规律，观察比较鼻小柱基部中点与两侧唇峰点所成三角形在正常上唇与唇裂患者中的差异，提出遵循几何原理的改良下三角瓣法，并进行临床应用。结果采用改良下三角瓣法整复158例。随访145例，139例整复效果满意，上唇三角形两侧唇部对称。结论改良下三角瓣法各个定点都较明确，有正确的理论基础，整复效果稳定、可靠。

Modification Inferior Triangular Flap Method Following Geometric Principle in Unilateral Cleft Lip Operation

Objective To investigate the modification inferior triangular flap method following geometric principle in order to advance the effect of traditional operation in unilateral Cleft lip repair. Methods The mark point systems of columella base and injured alar base were analysed with geometric principle, and compared the differences between normal people and unilateral cleft lip patients in the triangle consisting of midpoint of eolumella base and both peaks of Cupid＇s bow. Results 158 cases were repaired by this procedure, and 139 eases improved satisfactorily. The symmetry of bilateral lip in triangular upper lip recovered nice. Conclusion This technique is an available method to repair the cleft lip for its definite mark point and strict theory base.
