Pharyngolaryngeal function during swallowing was investigated cineradiographically in 22 patients with paresis of the recurrent nerve. Nineteen of these patients (86%) had defective closure of the laryngeal vestibule: 10 patients had defective apposition of the corniculate cartilages, (paresis of the oblique cricoarytenoid muscle), 9 patients had defective apposition of the arytenoid cartilages, (paresis of the interarytenoid muscle), 13 patients had defective movement of the epiglottis (paresis of, i.a. the thyrohyoid muscle), 1 patient had defective closure of the subepiglottic portion of the vestibule (paresis of the thyroepiglottic muscle), 2 patients had defective closure of the supraglottic portion of the vestibule (paresis of the superior ventricular segment of the thyroarytenoid muscle). Five patients with immobility of the epiglottis also had paresis of the pharyngeal constrictor musculature indicating paresis of the superior laryngeal nerve. Our investigation has shown that patients with paresis of the recurrent nerve who present with dysphagia with or without aspiration should be examined cineradiographically for pharyngolaryngeal function during swallowing.
对22例喉返神经麻痹患者的吞咽过程中的咽喉功能进行了X线电影造影研究。其中19例患者（86%）存在喉前庭关闭不全：10例患者小角软骨对合不良（环杓斜肌麻痹），9例患者杓状软骨对合不良（杓间肌麻痹），13例患者会厌运动不良（包括甲状舌骨肌等麻痹），1例患者前庭会厌下部分关闭不全（甲状会厌肌麻痹），2例患者前庭声门上部分关闭不全（甲杓肌上室段麻痹）。5例会厌固定的患者同时存在咽缩肌麻痹，提示喉上神经麻痹。我们的研究表明，对于有或无误吸的吞咽困难的喉返神经麻痹患者，应进行X线电影造影检查以评估吞咽时的咽喉功能。
