A Case of Laryngocele Marsupialized by Laryngomicrosurgery

Abstract

The case of an internal type of laryngocele in a 77-year-old woman is reported. Laryngoscopic examination showed a swelling of the right false cord, aryepiglottic fold and ventricle. CT imaging adjusted for lung examination revealed an air-filled mass in the paraglottic space. These findings led to a diagnosis of internal laryngocele. The mass had grown slightly by the next visit and the patient was admitted on the seventh day of disease. Tracheotomy was performed on the twelfth day under local anesthesia and the laryngocele was continuously marsupialized by laryngomicrosurgery under general anesthesia. On post-operative day 1, a comparatively high degree of edema of the right piriform sinus and false cord was observed. No recurrence of laryngocele has been indicated by laryngoscopic examination 18 months later, and CT imaging about 2 year after the operation showed only a small nodule in the right paraglottic space. Marsupialization of internal laryngocele by laryngomicrosurgery appears to be a low invasional and acceptable mode of treatment.
