Abstract
Pharyngoesophageal myotomy, performed in 16 laryngectomees to improve vocal rehabilitation, proved to have some negative side effects. Although no failures of speech rehabilitation using a button were consequently found, a considerable number of button assisted esophageal speakers had a breathy voice. Also, the number of poor injection-esophageal speakers was much higher than in the group of nonmyotomized laryngectomees. A "normal" pseudoglottis could only rarely be identified by fluoroscopy in the myotomized group. A significantly lower intratracheal pressure appeared to be required for tracheo-esophageal phonation after myotomy. To improve the slightly disappointing voice rehabilitation results of the myotomized laryngectomees, a modified myotomy is proposed.
