THE LARYNGOCELE consists of a dilatation of the appendix of the laryngeal ventricle of Morgagni, which at times is already predisposed because its amplitude is greater than the average. It rises from the anterior portion of the ventricle itself. The laryngocele can bulge into the larynx as a smooth, round-shaped mass, thereby forming an internal laryngocele, or it may extend outward into the cervical region through points of minor resistance, especially through the thyrohyoid membrane, thus forming an external laryngocele. This form is usually mixed, as it is associated with the internal form.
The characteristics of the extrinsic laryngocele are determined by its air contents. These characteristics are reducibility under pressure and modification of volume during acts of respiration (Keim and Livingstone1; Richards1a).
The association of laryngocele with cancer of the larynx has been described by some authors (Bonandini,1b Caliceti,2 Torchiana,3 Zöllner,4 Schall,5
