Laryngocoele is a rare entity, defined as an abnormal cystic dilatation of saccule of the laryngeal ventricle. Three types of laryngocele have been described, based on their relation to the thyrohyoid membrane: internal, external or mixed type. Symptoms are variable, including neck swelling, shortness of breath, dysphonia and fever, if the laryngocoele becomes infected. Patients may also present in extremis with airway obstruction. We present the case of a healthy 34-year-old gentleman with acute airway obstruction due to a mixed infected laryngocoele. Flexible nasoendoscopy showed a large cystic swelling arising from the laryngeal ventricle. Computed tomography of neck confirmed a right paraglottic collection extending into the ventricle and glottis, causing significant airway compromise. The patient was managed with microlaryngoscopy and cystic decompression. At outpatient follow up, he was completely asymptomatic and is currently under surveillance. Endoscopic decompression is a safe and effective initial management for mixed laryngocoele.
喉气囊肿是一种罕见的病症，定义为喉室囊的异常囊性扩张。根据其与甲状舌骨膜的关系，喉气囊肿已被描述为三种类型：内部型、外部型或混合型。症状各不相同，包括颈部肿胀、呼吸急促、发音困难，如果喉气囊肿感染还会出现发热。患者也可能在极端情况下出现气道梗阻。我们报告一例34岁健康男性因混合型感染性喉气囊肿导致急性气道梗阻的病例。软性鼻内镜检查显示喉室有一个巨大的囊性肿物。颈部计算机断层扫描证实右侧声门旁肿物延伸至喉室和声门，导致严重气道受压。该患者接受了显微喉镜检查和囊肿减压治疗。门诊随访时，他完全无症状，目前正在接受监测。内镜减压是混合型喉气囊肿安全有效的初始治疗方法。
