嗓音疾病患者行电子喉镜检查,观察声带运动情况,是目前耳鼻咽喉科的常规检查手段之一。通常需进行鼻腔、咽喉部黏膜表面麻醉,这种检查手段是否对声带运动产生影响,嗓音的声学分析是否发生变化;喉内镜导入后是否影响嗓音,这些均是目前研究的热点问题。本研究对嗓音疾病患者鼻腔 Conducted electronic laryngoscopy in patients with voice disease, the observation of vocal cord movement, is currently the routine examination of otolaryngology one of the means. Usually nasal and pharyngeal mucosal surface anesthesia is required. Whether this kind of examination has an influence on vocal cord movement or not, whether the acoustic analysis of the voice has changed or not, and whether the laryngeal endoscopy affects the voice, are all the hot issues in current research. This study addresses the nasal cavity of patients with voice disorders
