Aspiration has been frequently noted among patients suffering from vocal-fold paralysis. The association between a defect of glottal closure and aspiration in patients with unilateral vocal paralysis appears to have been rarely reported. The current study reviews collected data consisting of videotaped flexible nasoendoscopy and stroboscopy for patients with a unilateral vocal-fold paralysis. Mean normalized glottal gap areas for patients suffering vocal paralysis with associated aspiration are significant greater than that for the non-aspiration group. Subsequent to the surgical correction of the glottal gap, all patients recovered well from their earlier aspiration. The investigation of objectively derived data revealed that poor airway protection due to incomplete closure of the vocal fold was the major cause of aspiration for patients suffering unilateral vocal-fold paralysis. Intracordal autologous fat injection can successfully improve the breath control and eliminate aspiration in patients with vocal-fold paralysis.
在声带麻痹患者中，误吸现象屡见不鲜。单侧声带麻痹患者声门关闭缺陷与误吸之间的关联似乎鲜有报道。本研究回顾了收集到的单侧声带麻痹患者的视频柔性鼻内镜检查和频闪喉镜检查数据。伴有误吸的声带麻痹患者的平均标准化声门裂面积显著大于无误吸组。在对声门裂进行手术矫正后，所有患者的早期误吸症状均恢复良好。对客观获取的数据进行调查发现，声带闭合不全导致气道保护不佳是单侧声带麻痹患者误吸的主要原因。声带内自体脂肪注射可成功改善单侧声带麻痹患者的呼吸控制并消除误吸。
