title: Superior laryngeal nerve paralysis an often overlooked entity.
abstract: The anatomy and physiology of the larynx are discussed. The larynx is a dynamic structure, and motion pictures are helping to document and to clarify its dynamic behavior in the presence of diseases such as paresis and paralysis. The recognizable distinguishing features of unilateral and bilateral superior nerve paralysis are discussed in detail. These lesions often have gone unrecognized in the past and the patients mistakenly have been referred to the speech therapist with an incorrect diagnosis of "functional voice disorder."
