摘要
1目的 探讨腭咽阻塞器对腭裂术后腭咽闭合不全 (VPI)语音功能障碍的治疗作用。2方法 应用腭咽阻塞器治疗腭裂术后 VPI病人 84例 ,分别于治疗前、治疗后 0 .5 ,1.0 ,2 .0年 ,观察 VPI病人的腭咽闭合不全率(RVPI)、腭咽闭合不全改善率 (IRVPI)、各单元音共振峰频率 (F3)以及语音效果的变化。3结果 腭咽阻塞器治疗后 ,VPI病人的 RVPI逐渐降低 ,IRVPI逐渐增高 ,且各单元音共振峰 F3逐渐增高 ,接近正常人 ,与治疗前比较差异有显著性 (F=8.6 7～ 2 6 .2 6 ,P<0 .0 1)。去除阻塞器后 ,70 .2 %病人语音正常或接近正常。4结论 腭咽阻塞器治疗腭咽闭合不全具有恢复语音功能的作用。
Objective\ To explore the effect of treatment by oral prothesis on speech disorder caused by postoperative velopharyngeal incompetence (VPI) in patients with cleft palate.\ Methods\ We used oral prothesis for 84 patients with postoperative VPI. The rate of velopharyngeal incompetence(RVPI),improving rate of velopharyngeal incompetence(IRVPI),the value of the third formant frequency(F 3) of Chinese vowels and pronunciation were observed before and 0.5,1.0 and 2.0 years after treatment.\ Results\ RVPI was lower,IRVPI and the value of the third formant frequency(F 3) were higher in patients with VPI after treatment than before( F=8.67-26.26,P <0.01). Speech of all VPI patients made great progress after the treatment. Taking out the oral prothesis, the pronunciation was normal in 30 patients,and nearly normal in 29 patients.\ Conclusion\ Oral prothesis has an effect on improving the function of pronunciation of patients with VPI.
