| 摘 要： | 目的 对先天性腭咽闭合功能不合（ｃｏｎｇｅｎｉｔａｌ ｖｅｌｏｐｈａｒｙｎｇｅａｌ ｉｎｓｕｆｆｅｎｃｅ,ＣＶＰＩ）定量研究。方法 应用气流、气压测定仪对２７例ＣＶＰＩ患者测量口腔压力、鼻腔气流及腭咽闭合面积,比较ＣＶＰＩ患者在发ｈｅｍｐｅｒ和ｐａｐａ音时与正常语音者之间的变化值。结果 ＣＶＰＩ和正常语音两组间在口腔压力和腭咽闭合面积差异无显著性,但两组间的鼻腔气流量差异有显著性（Ｐ〈０．０７）。

| Abstract: | Objective To evaluate 27 congenital veloparyngeal insufficiency(CVPI) subjects and 6 normal articulation subjects with airflow pressure techniques Methods A compare analysis was performed in two groups (CVPI subjects and normal articulation subjects) during speech production of /hemper/ and /papa/ Results There wasn't statistical significance between two groups in oral air pressure and velopharyngeal orifice areas, however, CVPI group differed significanth in nasal airflow on the articulation of /hemper/ and /papa/ Conclusions When the degree of CVPI subject's VP opening was small, hypernasality appeared to be related to duration of the opening closing movements |
