A series of 76 patients referred for evaluation at the Oral-Facial and Communicative Disorders Program was studied in an attempt to determine the extent to which acoustic assessments of speech, made utilizing a Kay Elemetrics Nasometer, corresponded with clinical judgments of hyponasality and aerodynamic measurements of nasal cross-sectional area. Among the 38 adults, the sensitivity of Nasometer ratings in correctly identifying adult subjects with moderate to severe nasal airway impairment was 0.38, whereas the specificity was 0.92. Comparable analyses for the group of 38 children were not possible because of the extent to which nasal airway size varies up to the age of 15 years. Among the entire group of patients, the sensitivity and specificity of nasometry in correctly identifying the presence or absence of hyponasality was 0.48 and 0.79, respectively. However, when patients with audible nasal emission were eliminated from analysis, the sensitivity rose to 1.0 and the specificity rose to 0.85. Possible reasons for the findings obtained and their clinical significance are discussed.
在口腔面部与交流障碍项目中，对76例前来接受评估的患者进行了一项研究，旨在确定使用凯伊电子鼻测量仪（Kay Elemetrics Nasometer）进行的语音声学评估与鼻腔共鸣不足的临床判断以及鼻腔横截面积的气动测量结果之间的相符程度。在38名成年人中，鼻测量仪评级正确识别出中度至重度鼻气道损伤成年受试者的敏感性为0.38，而特异性为0.92。由于15岁之前鼻气道大小变化幅度较大，因此无法对38名儿童组进行类似分析。在整个患者组中，鼻测量法正确识别鼻腔共鸣不足存在与否的敏感性和特异性分别为0.48和0.79。然而，当将有可闻鼻漏气的患者排除在分析之外时，敏感性升至1.0，特异性升至0.85。文中讨论了所得结果的可能原因及其临床意义。
