The aim of this investigation was to study a wide range of dysphonic patients and determine the best matches among the laryngeal configurations on phonation for each patient and those previously established for control data, which were obtained from a professional voice user producing the whole range of voice qualities. Ninety-nine patients were selected and laryngeal photographs were produced for each patient. Fifteen laryngeal parameters were quantified and normalized. The data were sorted, scalar values assigned and a measure of similarity between configurations applied. The best, second-best, third-best and worst matches between each patient separately and the control data were then examined. Although 41% of the patients did not have particularly unusual configurations, 59% exhibited a narrowing of the laryngeal vestibule caused by epiglottic retraction, cuneiform fronting and/or false fold adduction. This suggests that clinical reports for patients with dysphonia should contain information not only on any lesions present but also on laryngeal configurations and, in particular, vestibular narrowing.
本研究的目的是对广泛的发声障碍患者进行研究，确定每位患者发声时的喉部结构与之前从能发出全范围音质的专业嗓音使用者获得的对照数据所确定的喉部结构之间的最佳匹配。选取了99名患者，并为每位患者拍摄了喉部照片。对15个喉部参数进行了量化和归一化处理。对数据进行分类，赋予标量值，并应用了一种喉部结构之间的相似性度量方法。然后分别检查了每位患者与对照数据之间的最佳、次佳、第三佳和最差匹配情况。虽然41%的患者没有特别异常的结构，但59%的患者表现出会厌后缩、楔状软骨前移和/或假声带内收导致的喉前庭狭窄。这表明，发声障碍患者的临床报告不仅应包含有关任何现存病变的信息，还应包含有关喉部结构，特别是前庭狭窄的信息。
