Paralysis of the lateral cricoarytenoid muscle: a case report as a contribution to the understanding of the functional anatomy of the larynx

In the last few years electromyography of the larynx (EMG) has become helpful in the evaluation of vocal fold immobility, especially to differentiate paralysis from fixation, and providing data for diagnosis, site of lesion and prognosis. Based on a case of selective paralysis of lateral cricoarytenoid muscle in a woman who had paralyzed vocal fold at lateral position, confirmed by electromyography study, we conducted an analysis in order to understand the role of intrinsic laryngeal muscles.
