Alaryngeal voice is usually accompanied by esophageal speech; however, about 40% of laryngectomy patients are unable to achieve adequate esophageal speech and must rely on mechanical devices for communication. A technique was developed for performing double-contrast studies of the hypopharynx, cervical esophagus, and pharyngo-esophageal segment using thick barium and the air normally injected for speech. Simultaneous audio and video recordings obtained during esophageal speech allowed correlation of the quality of speech with the motion of the pharyngo-esophageal segment. In 35 patients with various degrees of fluency in esophageal speech, normal and abnormal function of the pharyngo-esophageal segment was documented. Inadequate esophageal speech can be related to abnormal motion of the pharyngo-esophageal segment.
无喉语音通常伴有食管言语;然而,约40%的喉切除患者无法获得足够的食管言语,必须依靠机械装置进行交流。已开发出一种技术,使用浓稠钡剂和通常用于言语的注入空气,对下咽、颈段食管和咽食管段进行双重对比研究。在食管言语过程中获得的同步音频和视频记录,使言语质量与咽食管段的运动相关联。在35例食管言语流利程度各异的患者中,记录了咽食管段的正常和异常功能。食管言语不足可能与咽食管段的异常运动有关。
