This is due to the fact that the vocal folds terminate posteriorly at the vocal processes of the arytenoid cartilages, hence any manipulation of the cartilaginous glottis is propagated to a some extent to the membranous glottis.
A thorough microscopic evaluation of the injury with a blunt ball probe revealed that the arytenoid cartilage was properly positioned within the facets.
1) Type 1 laryngomalacia was characterized by prolapse of the mucosa overlying the arytenoid cartilages, type 2 involved foreshortened aryepiglottic folds, and type 3 involved posterior displacement of the epiglottis.
Laryngeal chondrosarcoma affects the cricoid cartilage (72% of cases) more than other laryngeal cartilages and more than thyroid and arytenoid cartilages.
The tumor most commonly arises within the cricoid cartilage (specifically, the posterior lamina), although the thyroid and arytenoid cartilages are occasionally affected.
25) They include (1) the inward collapse of the aryepiglottic folds, primarily the cuneiform cartilages, (2) an elongated epiglottis curled on an abnormality, (3) anterior and medial collapsing movements of the arytenoid cartilages, (4) posterior and inferior displacement of the epiglottis, (5) short aryepiglottic folds, and (6) an overly acute angle of the epiglottis.
Significant findings on examination included the presence of white lesions on the soft palate, erythema and edema of the arytenoid cartilages, and white lesions on the vocal folds (figure).
