Judging the movements of vocal cords in larynx paralysis

Abstract

In paresis of the recurrent laryngeal nerve the homolateral vocal cord cannot adduct or abduct, but some of the phonatory movements can still be seen in stro—boscopic light or on the high—speedfilm. A discussion of the conclusion which can, and also of those which cannot, be drawn from the return of the missing phonatory movement of the paretic vocal cord, the glottic wave, is presented.
