Abstract
An 82-year-old man who underwent vertical partial laryngectomy at the age of 65 years developed aspiration lasting for 2 years. In the previous surgery, the right half of the larynx was removed and a repair was conducted with the use of the piriform sinus mucosa. A laryngeal closure by means of the modified Habal & Murray technique was carried out with failure. The failure was caused by the existence of scar tissue in the right hemilarynx. The right piriform sinus was absent, causing a narrow hypopharynx.
The purpose of treatment under this condition was to establish a good food passage without voice conservation. To do this, the scarred right hemilarynx was removed together with the whole laryngeal skeleton and the myomucosal component of the left hemilarynx was preserved. A wide hypopharyngeal lumen was constructed with the use of the laryngeal myo-mucosal flap and the mucosa of the narrow hypopharynx. Postsurgical pharyngoesophagogram demonstrated smooth passage with no stenosis nor fistula formation.
