【摘要】 目的检测利用鼻咽纤维镜（ＮＰＦ）评价腭咽闭合功能的可靠性。方法对１６名发音无异常的成年男性进行了不同深度以及不同时间的ＮＰＦ检测。结果显示腭咽闭合不全率（ＲＶＰＩ）相对稳定。结论ＲＶＰＩ可作为评价腭咽闭合功能的指标，并具有良好的重复性和可靠性更多还原

【Abstract】 Objective To estimate the reliability of the nasopharyngeal fibroscope (NPF) for assessing velopharyngeal function. Methods 16 well pronounced males were examined by NPF which was positioned in different depth. Same procedures were repeated after a week. Results The results indicated that the rate of velopharyngeal incomptence (RVPI) of NPF had no significant difference when checked in different time and various depths. Conclusion RVPI can be used as a parameter of quantitative analysis for velopharyngeal function, and our results suggested that it is reliable and reproduciable.更多还原
