Accurate mapping of the defect of velopharyngeal closure in patients with velopharyngeal incompetence is paramount to the planning of an operative procedure that will have a successful outcome. Nasoendoscopy and videonasoendoscopy are valuable tools for examination of the abnormal pattern of velopharyngeal movement in patients with velopharyngeal incompetence. On the basis of the knowledge of the observed defect in velopharyngeal closure for the particular patient, a pharyngeal flap operation is planned. The flap width, level of placement of the flap base, and control of the lateral port size vary to suit each individual velopharyngeal closure defect. Postoperative speech results in 86 patients are reported.
准确描绘腭咽闭合不全患者的腭咽闭合缺陷，对于规划能够取得成功结果的手术程序至关重要。鼻内镜检查和视频鼻内镜检查是检查腭咽闭合不全患者腭咽运动异常模式的宝贵工具。根据对特定患者观察到的腭咽闭合缺陷的了解，计划进行咽瓣手术。瓣的宽度、瓣基底部的放置水平以及侧孔大小的控制会有所不同，以适应每个个体的腭咽闭合缺陷。报告了86例患者的术后语音结果。
