正常人腭咽闭合不全参数—X线头影测量研究

目的　建立正常人生理性腭咽闭合不全参数,为评价腭裂患者腭咽闭合功能和软腭活动提供一种客观的方法。方法　采用 Ｘ 线头影定位测量分析技术对 ２２２ 名腭咽闭合不全（ｖｅｌｏｐｈａｒｙｎｇｅａｌｉｎｃｏｍ ｐｅｔｅｎｃｅ, Ｖ Ｐ Ｉ）的正常人群进行分析研究,建立了正常人 Ｘ线头颅定位测量腭咽闭合功能参数。结果　 Ｘ 线的腭咽闭合矢状收缩不全率（ Ｒ Ｖ Ｓ Ｒ）与鼻咽内窥镜检查的腭咽闭合不全率（ Ｒ Ｖ Ｐ Ｉ）呈显著的相关关系。结论　 Ｘ 线头影测量方法是评价腭咽闭合功能和软腭活动的一种有效方法。

The normal people's parameters of the velopharyngeal incompetence(VPI) by cephalometric analysis

Objective To estimate velopharyngeal incompetence(VPI)in patients with cleft lip and palate,we seek for the normal people's parameters of VPI. Methods Studying on 222 normal people with VPI by cephalometric analysis,the parameters of the normal people have been set up. Results There was remarkable correlationship between the rate of velopharyngeal sagital restriction by cephalometric analysis and the rate of VPI by nasopharyngeal endoscope. Conclusion Cephalometric analysis is useful to estimate the function of velopharyngeal closure and mobility of the soft palate.
