A morphometric study of the laryngeal saccule and sinus.

A morphometric study of 111 larynxs from both sexes was performed with the initial intention of assessing the incidence of asymptomatic laryngeal pouches. Certain basic measurements were made also to determine the dimensions of the laryngeal saccule and sinus relative to the height and width of the larynx in the two sexes. Asymptomatic pouches were found in 2 patients, one from each sex and there was no obvious difference in the height of the saccule relative to the height of the larynx in the two sexes. However, since the male larynx was deeper in the anteroposterior plane relative to its height, the male saccule tended to be relatively shallower than the female.
