项目摘要

The purpose of this study is to establish a strategy to stimulate velopharyngeal function using speech bulb reduction. To determine an adequate reduction volume of the bulb, levator muscle activity associated with changes in nasal air flow rate and oral air pressure was monitored when respiratory air was allowed into the nasal cavity through the opening drilled in the vertical center of the bulb of a speech appliance. The opening area was varied from 0 (occluded condition) to 38.5mm^2 through 12.6mm^2. Multiple regression analyzes showed that levator muscle activity correlated with nasal air flow rate and oral air pressure, while nasal air flow rate contributed to the changes in levator muscle activity more significantly than oral air pressure did. Based on the results, prototype strategy of bulb reduction therapy was designed and applied to 5 repaired cleft palate patients who were routinely wearing a speech appliance. That is, bulb reduction was performed so that decrease in the bulb volume could be equal to the circular area ranged from 12.6mm^2 to 38.5mm^2 in horizontal projection. The reduction was carried out monthly for 3 months. Nasopharyngeal fiberscopic and perceptual evaluations were carried out onemonth after each reduction. As results, four out of five subjects showed complete closure of the velopharynx and no nasal emission during obstruent speech, and the improved veloharyngeal function was observed in each evaluation. However, another subject showed complete closure in first and second evaluation, while third evaluation did not show any improvement. The results suggested that this prototype of bulb reduction strategy might be effective for the improvement of velopharyngeal function, while the process towards improved velopharyngeal function might be variable across subjects. A maintenance of the reduction effect warrants future study.

这项研究的目的是建立一种使用言语鳞茎降低刺激咽咽功能的策略。为了确定灯泡的足够减小的体积，当允许呼吸空气允许呼吸空气进入鼻腔中，通过在语音的垂直中心钻进鼻腔时，监测与鼻气流和口服气压变化相关的悬浮肌活动。器具。开放区域从0（遮挡条件）到38.5mm^2至12.6mm^2。多次回归分析表明，悬臂肌肉活性与鼻气流和口服气压相关，而鼻气流速度与口服气压相比，鼻腔流速更大。根据结果，设计并应用了5名经常戴上语音设备的修复后的left裂患者的原型策略。也就是说，进行灯泡的减小，因此灯泡体积的减小可以等于水平投影中12.6mm^2至38.5mm^2的圆形面积。减少每月进行3个月进行。每次还原后，进行鼻咽纤维纤维和感知评估。结果，五分之四的受试者显示了尾咽部的完全关闭，并且在optrut语音期间没有鼻发射，并且在每次评估中都观察到了改善的Veloharyngeal功能。但是，另一个受试者在第一次和第二次评估中显示出完全关闭，而第三次评估没有显示出任何进步。结果表明，这种灯泡还原策略的原型可能有效地改善咽咽功能，而改善静脉咽咽功能的过程可能会在受试者之间变化。减少效应的维护需要未来的研究。
