ar·y·te·noid car·ti·lage

[TA]
one of a pair of small triangular pyramidal laryngeal cartilages that articulate with the lamina of the cricoid cartilage. It gives attachment at its anteriorly directed vocal process to the posterior part of the corresponding vocal ligament and to several muscles at its laterally directed muscular process. The base of the cartilage is hyaline but the apex is elastic.

Etymology: Gk, arytaina, ladle + eidos, form; L, cartilago

arytenoid

shaped like a jug or pitcher, as the arytenoid cartilage.

arytenoid abscess
see laryngeal chondritis.
arytenoid cartilage
one of the paired laryngeal cartilages in the dorsal part of the larynx that provides attachment for the muscles that adduct and abduct the vocal cords. The cartilages form the dorsal boundary of the rima glottis, the vocal cords the ventral boundary.
arytenoid chondritis
inflammation of the arytenoid cartilage that causes a syndrome similar to that caused by recurrent laryngeal nerve paralysis.
arytenoid lateralization
a surgical technique used to treat laryngeal paralysis in dogs. One or both arytenoid cartilages are fixed in a lateral position with sutures, thereby enlarging the diameter of the laryngeal lumen.

The cartilaginous skeleton contains the vocal cords (thyroarytenoid muscles) and comprises the thyroid, cricoid, and arytenoid cartilages.
The vocal fold was taut, not lax, and the arytenoid cartilage was more posteriorly positioned than would be expected with an anterior dislocation.
9) Their patient was a 62-year-old woman who had swallowed a fish bone, which then became stuck in her right cricoarytenoid joint and prevented rotation of her arytenoid cartilage.
Flexible laryngoscopy detected a submucosal 2-cm mass that bulged out from the left postcricoid area; the mass covered the ipsilateral piriform sinus and arytenoid cartilage (figure 1).
A 5-0 Vicryl suture was used to reapproximate the vocal process to the exposed arytenoid cartilage along its medial surface.
5) In fact, fewer than 10 cases of chondrosarcoma of the arytenoid cartilage have been reported in the literature.
However, we did make an incidental finding of a small swelling on the right arytenoid muscle adjacent to the arytenoid cartilage (figure 1).
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.
Also evident were swelling of the left true vocal fold, the stigmata of radiation laryngitis, and diffuse white patches on the false vocal folds and arytenoid cartilages bilaterally.
The arytenoid cartilages were mildly edematous and moderately erythematous.
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.
