The objective of this study was to describe a case of epiglottic entrapment in a cat.
A 5-month-old male neutered Russian Blue cat was evaluated for progressive stertorous upper airway sounds, acute onset vestibulopathy and abnormal laryngeal anatomy. Endotracheal intubation was only able to be achieved using videoscopic guidance and identified concern for severe nasopharyngeal stenosis. A computerized tomography scan revealed otitis interna, narrowed nasopharynx and no definitive cause for the stertorous breathing. The cat recovered very slowly from anaesthesia due to concern for airway obstruction following extubation. It was discharged the following day and then passed away at home 2 weeks later. Necropsy revealed that the epiglottis was obscured by 2 cm of redundant mucosal tissue extending from the base of the tongue to the larynx resulting in epiglottic entrapment. Also noted was chronic, severe otitis interna and externa. Upper airway obstruction is suspected to be the cause of sudden death.
To the authors' knowledge, this is the first report of these oropharyngeal anatomic abnormalities in a cat.
本研究旨在描述一例猫的会厌嵌顿病例。
一只 5 月龄雄性去势俄罗斯蓝猫因进行性喘鸣性上呼吸道杂音、急性前庭病和异常喉解剖结构而接受评估。仅使用视频镜引导才能进行气管内插管，并发现严重的鼻咽狭窄。计算机断层扫描显示中耳炎、鼻咽狭窄，无明确导致喘鸣呼吸的原因。由于担心拔管后气道阻塞，猫在麻醉后恢复非常缓慢。第二天出院，2 周后在家中死亡。尸检显示，会厌被 2 厘米长的多余黏膜组织从舌根部延伸至喉部遮挡，导致会厌嵌顿。还注意到慢性、严重的中耳炎和外耳炎。上呼吸道阻塞疑为导致其突然死亡的原因。
据作者所知，这是猫的这些口咽解剖异常的首次报道。
