腭咽闭合功能不全语音清晰度评价

The evaluation of the Chinese intelligibility of patients with velopharyngeal incompetence

目的 研究腭咽闭合功能不全患者的语音清晰度。方法 10 0例腭咽闭合功能不全患者 ,其中 15例为腭裂 ,2 1例为先天性腭咽闭合不全 ,5 6例为腭裂术后腭咽闭合不全 ,8例为咽成形术后腭咽闭合不全 ,对照组为 32名健康人。 3名语音专业人员共同评价汉语语音清晰度 ,并且分析语音障碍和语音清晰度的关系。结果 健康组的语音清晰度为 99 0 % ,腭咽闭合功能不全组为35 5 % ,其中未手术腭裂组为 19 9% ,先天性腭咽闭合不全为 32 8% ,腭裂术后腭咽闭合不全为4 0 3% ,咽成形术后腭咽闭合不全为 35 2 % ,统计分析显示健康组和病例组各类型之间差异有显著性 (P <0 0 1)。结论 ①腭咽闭合功能不全异常语音的语音清晰度差 ,并伴过度鼻音 ;②腭咽闭合不全异常语音中 ,腭裂患者的语音清晰度最低 ,其余依次为先天性腭咽闭合不全。

Objective To study the Chinese intelligibility of patients with velopharyngeal incompetence(VPI) Methods 100 patients with VPI and 32 normal students were selected for this study Of 10 patients, 15 with cleft palate, 21 with congenital velopharyngeal incompetence, 56 with post palatoplasty VPI and 8 with post pharyngoplasty VPI Chinese intelligibility was measured by three speech pathologists and relation between degree of abnormal articulation and Chinese intelligibility were studied Results Chinese intelligibility of the controls was 99 0% and the patients with VPI were 35 2% Of the patients, the cleft palate was 19 9%,the congenital velopharyngeal incompetence was 32 8%, the post palatoplasty VPI was 40 3% and the post pharyngoplasty VPI was 35 2% The data showed obvious difference among the controls and sub types of VPI ( P <0 01) Conclusions ①Chinese intelligibility of VPI accompanied with hypernasality is worse ②Of misarticulation of VPI, the cleft palate is the worst, in turn the others are the congenital velopharyngeal incompetence, the post pharyngoplasty VPI and the post palatoplasty VPI
