Voice quality in patients with vocal fold paralysis can be affected by several factors, such as the position of the paralyzed vocal fold, its degree of atrophy, the configuration of its free edge, and the level differences between both vocal folds. Depending on the related vocal deficiency the patient will attempt to compensate using different maneuvers, such as increment of vocal tract and neck muscle contraction to improve glottal closure. This is probably one of the reasons why ventricular folds are frequently requested. The objective of this study is to analyze the behavior of the homolateral and contralateral vestibular folds to delineate patterns of vestibular motion during sustained phonation, in cases of unilateral vocal fold paralysis.
声带麻痹患者的嗓音质量会受到多种因素的影响，例如麻痹声带的位置、萎缩程度、游离缘形态以及双侧声带之间的水平差异。根据相关的嗓音缺陷，患者会尝试采用不同的动作进行代偿，例如增加声道长度和收缩颈部肌肉以改善声门闭合。这可能是频繁要求观察室带的原因之一。本研究的目的是分析单侧声带麻痹患者在持续发声过程中同侧和对侧前庭襞的运动情况，以描绘前庭运动模式。
