梯度旋转下降法修复单侧完全性唇裂的初步研究

目的探讨梯度旋转下降法修复单侧完全性唇裂的术后效果。方法分析85例单侧完全性唇腭裂患儿的术前，术后即刻以及术后一年的面部石膏模型唇部指标，同时比较这85例单侧完全性唇腭裂患儿术后一年的唇部指标与相似年龄的45例单纯不完全性腭裂患儿的唇部指标。结果在术后即刻虽然健患侧唇高、健患侧唇宽的差值减小，但其健患侧仍不协调。术后一年，健患侧唇高和健患侧唇宽都达到协调。与对照组进行比较，唇高在术后一年恢复到正常值，而唇宽在一年后无论是健侧还是患侧，仍然低于正常值。结论采用梯度旋转下降法修复单侧完全性唇裂可以达到一个很好的唇部美观效果。

A new technique of primary repair for unilateral cleft lip patients

Objective To discuss the post-operative effect of primary lip repair of unilateral complete cleft lip （UCCL） according to the theory of rotation advancement step by step. Methods Labial parameters of 85 UCCL cases pre-operation, immediately after operation and 1 year post-operation were compared. Furthermore, 1 year post-operative labial parameters of theses 85 UCCL cases were compared with labial parameters of 45 incomplete cleft palate only （CPO） patients of similar age. Results lip height and lip width are asymmetric between the cleft and non-cleft side immediately after the operation, however the differences between the two sides markedly decreased. One year later, both parameters are symmetric between the cleft and non-cleft side. In comparison with the control group, lip height is normal one year after the operation but the lip width is significantly shorter than normal on both sides. Conclusion The theory of rotation advancement step by step could achieve excellent results, making the lip appearance more nature.
