Pharyngoesophageal myotomy for vocal rehabilitation of laryngectomees. 1987

H F Mahieu, and A A Annyas, and H K Schutte, and E J van der Jagt

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.

D010609 Pharyngeal Muscles The muscles of the PHARYNX are voluntary muscles arranged in two layers. The external circular layer consists of three constrictors (superior, middle, and inferior). The internal longitudinal layer consists of the palatopharyngeus, the salpingopharyngeus, and the stylopharyngeus. During swallowing, the outer layer constricts the pharyngeal wall and the inner layer elevates pharynx and LARYNX.
