Pharyngoesophageal myotomy for vocal rehabilitation of laryngectomees.
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.
