Thirty-one patients with surgically repaired cleft palate who had velopharyngeal deficiency and compensatory articulatory defects in comparison to hyperrhinophony were studied. All patients were submitted to a videonasopharyngescopic and videofluoroscopic study of multiple incidence before and after speech therapy in order to correct the compensatory articulation. The movement proportions of the pharyngeal velum structures increased significantly after the correction of the compensatory articulation. Even moreso, the size of the pharyngeal velum defect decreased significantly. The results of this study support the postulate which recommends that the articulatory abnormalities associated to hyperrhinophony should be corrected before surgery for pharyngeal velum insufficiency secondary to the closure of the cleft palate.
对31例接受过腭裂手术修复、存在腭咽闭合不全以及与过度鼻音相关的代偿性发音缺陷的患者进行了研究。所有患者在言语治疗前后均接受了多次视频鼻咽喉镜和视频荧光镜检查，以纠正代偿性发音。代偿性发音纠正后，咽腭结构的运动比例显著增加。更重要的是，咽腭缺损的大小显著减小。本研究结果支持这样一种假设，即对于腭裂闭合后继发的咽腭功能不全，在手术前应纠正与过度鼻音相关的发音异常。
