Acquired laryngo-pharyngeal fistula is a very rare condition. This paper reports a 65-year-old man who presented with a laryngo-pharyngeal fistula caused by trauma to the cervical vertebra. The symptom was persistent aspiration. The fistula was located between the subglottic space and the hypopharynx through the cricoid lamina. A fluoroscopic video recording was useful in demonstrating the fistula, and a fibrescopic examination confirmed its existence and exact location. The fistula was successfully treated with closure of both larynx and pharynx with a sternomastoid muscle interposition.
后天性喉咽瘘是一种非常罕见的病症。本文报告了一名65岁男性，其因颈椎外伤导致喉咽瘘。症状为持续性误吸。瘘管通过环状软骨板位于声门下间隙与下咽之间。透视视频记录有助于显示瘘管，纤维镜检查证实了其存在及确切位置。通过胸锁乳突肌置入进行喉和咽的封闭，成功治疗了该瘘管。
