The interarytcnoid (IA) muscle has rarely been studied in the living larynx. In this work, the role of the IA muscle in phonation was studied in three dogs by means of an in vivo phonation model. The isolated action of the IA muscle was studied by sectioning and stimulating its nerve branch. As IA activity increased, subglottic pressure increased significantly until a plateau was reached. In the absence of superior laryngeal nerve stimulation, the fundamental frequency rose with increasing IA activity. In the presence of superior laryngeal nerve stimulation, however, no significant change in fundamental frequency was observed with increasing IA activity. Measurement of adductory force demonstrated that the IA muscle adducts primarily the posterior vocal fold. In this canine model, phonation was not possible without IA stimulation, owing to a large posterior glottic chink.

Laryngologists have long recognized that assessment of the mucosal wave is an important part of laryngeal evaluation. This is the first report of a noninvasive measurement of vocal fold displacement velocity in an in vivo canine model. a newly developed calibrating endoscopic instrument capable of measuring distances on the vocal fold surface is described. Displacement velocity was determined in three dogs and compared to physiologic measures in the in vivo phonation model. The results indicate that the calculated displacement velocity is linearly proportional to traveling wave velocity and fundamental frequency. Because traveling wave velocity has been shown to reflect vocal fold stiffness, this method may advance the usefulness of stroboscopy for the study of mucosal wave abnormalities.
