唇腭裂术后鼻唇畸形修复同期行鼻中隔偏曲矫正术对鼻气道阻力的影响

目的：探讨唇腭裂患者二期鼻唇畸形修复同期行鼻中隔偏曲矫正术对鼻气道阻力的影响。方法：应用主动性前鼻测压法，测定18例唇腭裂患者二期鼻唇畸形修复时同期行鼻中隔偏曲矫正手术前后鼻气道阻力和主观鼻开放感觉的评分情况。结果：18例患者术前鼻气道阻力为（0．664±0．200）kPa／（s·L）；术后6个月为（0．304±0．180）kPa／（s·L），12个月为（0．396±0．250）kPa／（s·L），术后6个月和12个月分别与术前比较，差异均有统计学意义（均P〈0．01）。术前主观鼻开放感觉评分为7．5±1．5，术后6个月为2．1±2．0，12个月为3．0±2．4，术后6个月和12个月分别与术前比较，差异均有统计学意义（均P〈0．01）。结论：鼻中隔偏曲的矫正应视为唇腭裂鼻唇畸形整复的重要内容之一，可显著降低患者的鼻气道阻力，同时患者的鼻通气功能也得到了明显改善。

The effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty on nasal airway resistance

Objective：To assess the effect of one-stage repair of secondary nasolabial deformity and nasal septoplasty for cleft patients on nasal airway resistance（NAR）. Method：Using active anterior rhinomanometry, NAR was measured in eighteen patients with cleft lip and palate who suffered form one stage repair of secondary nasolabial deformity and septoplasty at per-and-post operation. Result： NAR was（0. 664±0. 200）kPa/（s · L）before op eration,（0.304±0.180）kPa/（s. L） six months after operation,and（0.396±0.250）kPa/（s · L） twelve months after operation respectively. The differences are statistically significant（P〈0.01）between the NAR before and af- ter operation. Subjective impression score of nasal patency was 7.5 ± 1.5 before-operation, 2. 1± 2.0 after-opera- tion for six months,3.0± 2.4 after-operation for twelve months. There are significant differences in the subjective impression score of nasal patency as well（P〈0.01）. Conclusion：Correction of septal deformities play a very impor- tant role in the operation for secondary nasolabial deformity, which can decrease NAR and improve the subjective impression of nasal patency.
