Various studies have reported that sparing both arytenoid cartilages
speeds recovery of swallowing after SCPL (3, 4, 6, 9).
In 2 cases, the cricoid and arytenoid cartilages
lacked calcification and were not visible.
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.
(1,2) Their presence there may lead to an expansion of the circumference of the laryngeal inlet, lateral displacement of the arytenoid cartilages
, and consequent glottic insufficiency.
(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
. (1,2) The most common symptoms are hoarseness, dyspnea, and dysphagia, in that order.
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.
