A new experimental method for assessment of velopharyngeal adequacy/inadequacy, using nasal manometric pressure readings for three types of speech conditions under controlled incremental bleed conditions, is described. Cleft palate speakers (N = 30) tended to have higher nasal pressure readings than non-flect palate speakers (N = 56), with or without bleed conditions. Reduction in nasal pressure under controlled incremental bleed for non-cleft palate speakers and cleft palate adequate (CPA) speakers is compatible with an aerodynamic quadratic equation. Unlike cleft palate inadequate (CPI) speakers, non-cleft palate speakers and CPA speakers exhibit similar ability to achieve 0 cm nasal monometric pressure under a bleed bore diameter of 4 mm for a circular bleed orifice. Results for cleft palate marginal (CPM) speakers are less conclusive. Reliability of nasal manometric bleed testing was limitedly tested but not conclusively established in the present report. Further study of reliability and validity is necessary.
本文描述了一种新的实验方法，用于评估腭咽功能正常/异常，该方法是在可控的渐进性出血条件下，针对三种语音条件使用鼻测压读数。腭裂患者（N = 30）无论有无出血情况，其鼻压读数往往高于非腭裂患者（N = 56）。对于非腭裂患者和腭咽功能正常（CPA）的腭裂患者，在可控的渐进性出血情况下鼻压降低符合空气动力学二次方程。与腭咽功能不全（CPI）的腭裂患者不同，非腭裂患者和CPA患者在圆形出血孔直径为4 mm的出血情况下，具有相似的能力将鼻测压压力降至0 cm。腭咽功能临界（CPM）的腭裂患者的结果不太明确。本报告中对鼻测压出血测试的可靠性进行了有限的测试，但尚未最终确定。有必要进一步研究其可靠性和有效性。
