The larynx of old persons has frequently been examined. However, a perusal of the literature reveals that no two physicians agree in their findings as far as the muscles of this organ are concerned. Kofler1 mentioned slight atrophy of the muscles, without giving further details, and Imhofer2 found that the lipoid pigment usually situated around the nuclei of the sarcolemma increased in amount in old persons. Segre3 found simple atrophy of the adductor and the abductor muscles, characterized by an increase of the nuclei of the sarcolemma and an increase in both the collagenous and the elastic fibers. This atrophy was least marked in the interarytenoid and the vocal muscles. In contrast, Imhofer4 did not observe an increase in elastic fibers. The cricothyroid muscles showed hypertrophy in the cases of Segre,3 which was considered compensatory, because of the atrophy of the adductor muscles. Carnevale Ricci5 described essentially the same conditions
