DISEASES OF THE VENTRICLE OF MORGAGNI: WITH SPECIAL REFERENCE TO PYOCELE OF A CONGENITAL AIR SAC OF THE VENTRICLE

Abstract

To the average laryngologist the ventricle of the larynx is merely a slit between the true and false vocal cords, as it was to Galen in 300 A. D. It was Morgagni, in 1741, who described it more fully and after whom it is named. John Hilton¹ in 1837 gave a most accurate and detailed description of a series of fine dissections which he made of this space. It was he who drew attention to the anterior upward projection of the horizontal slit of Morgagni to form the anterior vertical blind pouch, known as the sacculus ventriculi laryngis (fig. 1). Irwin Moore² said: This sacculus lies between the ventricular band and the inner surface of the thyroid cartilage. It extends directly upwards from the anterior part of the ventricle and represents the air-sacs which in anthropoid apes are connected with the ventricle. The sacculus varies greatly in size and shape;
