应用鼻咽镜对74例腭裂术后患者腭咽闭合功能的评价

The Evaluation of Velopharyngeal Function in 74 Patients with Operated Cleft Palate Using NPF

应用鼻咽镜(NPF)对74例完全性腭裂术后患者进行了随访,术式均为二大瓣术。48例术后腭咽闭合功能良好,手术成功率为64.86%(48/74)。术后腭咽闭合不全(VPI)发生率有随手术年龄增大而增高的趋势,且 VPI 病员半环状和环状关闭类型比例明显高于手术后腭咽闭合完全的病员(X^2=6.39,P<0.05)。作者分析了其原因并提出预防和改进措施。对需要行咽成形术者,作者建议先作NPF检查,根据咽侧壁的不同活动度来设计手术方法,可提高手术成功率。

This paper followed-up 74 cases of completed cleft palate repaired with two flapspalatoplasty(or plus vomer flap).All cases were examined using NPF.The extentsof VPI were quantitatively analysed.The VPF of 48 cases were normal,so the success rateof operation was 64.86%(48/74).The incidence of VPI in the post-operativepatients had a tendency that the older the operative age was,the higher the rate was,but no significant difference was found in statistical analysis(x^2=4.41,P>0.05).Thepercentage of semi-circular and circular closure patterns was distinct higher in VPI gro-up than in velopharyngeal competence group(x^2=6.39,P<0.05).The authors analysed thereason of this difference and suggested,for patients need pharyngoplasty to treat VPI,theevaluation of VPF prior to operation using NPF be necessary,it can help doctors to designa more exact pharyngoplasty regime according to the extent of lateral pharyngeal wallmotion.
