Three methods of pharyngeal flap surgery were analyzed with multiview videofluoroscopy and nasopharyngoscopy at least six months post-operatively. It was found that, by varying the type of insertion of the flap into the palate, post-operative flap width could be "tailored" to the size of the gap in the velopharyngeal sphincter. The value of varying flap width according to gap size was assessed by analyzing speech results in 60 patients specifically assigned for narrow, moderate, or wide flaps. Results show a marked improvement in the effectiveness of pharyngeal flap surgery when operations are prescribed according to the degree of lateral pharyngeal wall motion seen pre-operatively.
在术后至少六个月时，采用多视角电视荧光吞咽造影检查和鼻咽喉镜检查对三种咽瓣手术方法进行了分析。研究发现，通过改变咽瓣在腭部的植入方式，术后咽瓣宽度可根据腭咽括约肌间隙大小进行“定制”。通过分析专门接受窄、中、宽咽瓣手术的60例患者的语音结果，评估了根据间隙大小改变咽瓣宽度的价值。结果显示，根据术前观察到的咽侧壁运动程度来安排手术时，咽瓣手术的有效性有显著提高。
