會厭之巨大扁桃囊腫－病例報告
Huge Tonsillar Cyst of the Epiglottis - Case Report
摘要
喉部囊腫為良性非贅生性疾病，約占喉部良性腫瘤的6%。喉部囊腫發生的部位以會厭及真聲帶最多，其中又以會厭的舌表面為多。會厭囊腫的症狀依病人的年齡以及腫的大小而有所不同。在小孩常以呼吸道症狀為主，而大人則以無症狀、咽喉異物感或吞嚥困難來呈現。本科於1995年1月及6月先後經歷了兩個巨大會厭囊腫的病例，病人皆乏自覺症狀，一個是在麻醉插管時、另一個是因為感冒做喉鏡檢查時意外發現的。兩例皆在全身麻醉下，一以經舌骨上型咽切開術、另一以直接喉鏡術摘除囊腫。囊腫直徑皆約3 cm。術後病理報告同為扁桃囊腫。因為如此巨大的會厭囊腫並不常見，特提出報告，並就喉部囊腫的臨床症狀、治療方法、分類及發生原因加以討論。
並列摘要
Laryngeal cyst, an uncommon benign non-neoplastic disease, comprises approximately 6% of benign laryngeal tumors. The majority of laryngeal cysts occur at the epiglottis and true vocal cords, especially in the lingual surface of the epiglottis. The symptoms of laryngeal cysts vary with the age of patients and the size of the cyst. Children usually present with air-way symptoms, whereas adults may remain asymptomatic or present with foreign body sensation in the throat and/or dysphagia. We encountered two cases of epiglottic cyst in January and June 1995 respectively. Both had no subjective complains. Case 1 was discovered incidentally when undergoing anaesthetic intubation. Case 2 was detected unexpectedly on laryngoscopy for a common cold. Under general anesthesia, case 1 underwent cyst removal through suprahyoid pharyngotomy and case 2 via direct laryngoscopy. Both cysts were approximately 3 cm in diameter. On pathological examination, both of the cysts showed the histological characteristics of tonsillar cyst. The cases are presented because such cysts of such size are uncommon. The symptoms, treatment and classification as well as etiology of laryngeal cysts are also reviewed and discussed.
