Much has been written about pathologic conditions of the larynx and the accessory organs of phonation, and especially about acute and chronic hoarseness, for which many possible etiologic factors are given. It is unnecessary to enumerate here these various disturbances, since the present paper is concerned only with "functional hoarseness."
Pryor1 remarked concerning phonatory disturbances:
To the general practitioner the larynx has always been more or less of a land of mystery. Up until a few years ago there was probably less known about this organ by ear, nose and throat specialists than any other one single phase of their work.
In 1941 these remarks still hold true in regard to the condition of functional hoarseness. In glancing through the literature on the subject one finds many promising attempts to uncover the mystery surrounding functional hoarseness, but nowhere a full explanation and statement of its treatment.
