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。
1 Objective To investigate the therapeutic effect of velopharyngeal occluder on speech dysfunction of velopharyngeal insufficiency (VPI) after cleft palate. Methods Two hundred and eight patients with VPI after cleft palate were treated with velopharyngeal occluder. The VPI patients were divided into two groups: VPI patients before and after treatment at 0.5, 1.0 and 2.0 years, and the VPI patients’ RVOP, Incomplete rate of improvement (IRVPI), per unit formant frequency (F3), and changes in speech effects. 3 Results After the palate pharyngeal occluder treatment, the RVPI of VPI patients decreased gradually and IRVPI increased gradually, and the F3 of each vowel tone increased gradually and approached to the normal level, the difference was statistically significant (F = 8.67-2.6 .2 6, P <0. 0 1). After removing the occluder, 70.2% of patients had normal or nearly normal speech. 4 Conclusion velopharyngeal occluder treatment of velopharyngeal insufficiency has the function of restoring speech function.
