先天性腭咽闭合功能不全的临床分类

Classification of congenital velopharyngeal insufficiency

目的 :研究先天性腭咽闭合功能不全 (CVPI)的临床分类及其各组间在形态和功能上的差别。方法 :按有腭隐裂和无明显的腭部异常将 30例CVPI患者分为 1类、II类 ,通过口腔检查 ,头颅侧位定位片来观察各组间的形态和功能上的表现及差异。结果 :12例CVPII类患者 ,其软腭长度 ,咽腔深度及needratio与 2 0例对照组相比均有显著性差异 ,18例CVPIII类患者的咽腔深度 ,needratio同对照组相比有显著差异 (P <0 .0 5 ) ,其中 4例患者的软腭动度在 0～ 5度。结论 :I类患者除了有腭隐裂 ,X线片上也显示出软腭长度过短 ;而II类患者的口腔表现不明显 。

Objective: To study the classification of congenital velopharyngeal insufficiency(CVPⅠ).Methods:30 patients with CVPI were divided into 2 groups.The patients in group I were with submucous cleft palate,those in group Ⅱwere without noticible abnormality.A11 patients received oral examination and 1ateral cephalogram examination. ANS-PNS(1ength of hard palate),PNS-U(velar 1ength),PNS-PPW(pharyngeal depth),SPT(thickness of soft palate),need ratio, elongation and upward angle of soft palate were measured. Results:PNS-U was shorter and PNS-PPW was longer in the patients than in the health controls (P<0.05),the need ration in the patients was heigher than that in the health controls (P< 0.05).No statistic difference was found in other parameters among the groups.Conclusion:Shorter soft palate and insufficient mobility of palatopharyngeal muscle are related to the congenital velopharyngeal insufficiency.
