A Case of Hypopharyngeal Diverticulum Developed after Total Laryn gectomy

Abstract

A case of hypopharyngeal diverticulum was reported. This patient has had repeated surgical treatinents for recurrent fistula developed after total laryngectomy with radical neck dissection.
The diverticulum was removed surgically. Histological examination revealed that the inner wall was lined with pharyngeal mucosa.
It seemed reasonable to conclude that pseudod iverticulum in the early stage was developed gradually to the genuine one due to mucosal preparation to the skin.
