Abstract
|
|
|
Laryngeal cyst, particularly epiglottic cyst, was usually benign. This was uncommon and constituted approximately
5% of benign laryngeal lesions. There was usually asymptomatic in adult, but might be symptoms, such as hoarseness,
foreign-body sensation, pain, or dysphagia. Although a laryngeal cyst was harmless to the patient, the discovery
of this in the intubation of anesthesia was a potentially life-threatening problem. We experienced a case of
the large asymptomatic laryngeal cyst which caused the unanticipated difficult intubation. A 70-year-old man had
a lumbar herniation of nucleus pulposus. At the elective discectomy of neurosurgical department, the anesthetist
noted a large mass at epiglottis and had difficulty with the oropharyngeal intubation. This patient had transferred
to oto-rhino-laryngologic department. Direct laryngoscopy revealed about 5 cm sized cystic mass on the lingual
surface of epiglottis occupying vallecular area. Despite its size, the patient had remained asymptomatic. After some
days, we performed the awake needle aspiration of epiglottic cyst, and then this was excised by CO2 laser under
microscopic laryngoscopy. Histologically, this cyst was the tonsillar cyst lined by the squamous epithelium with
underlying lymphoid follicles according to modified working classification.7) Eighth months later, there was no
recurrence.
