摘　　要：目的　对先天性腭咽闭合功能不全 (congenitalvelopharyngealinsuffence ,CVPI)定量研究。方法　应用气流、气压测定仪对 2 7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 0 7)。结论　诊断CVPI仅用传统的 0 2 0cm2 这一标准不能真实反映腭咽闭合功能 。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
