The logic behind this idea was purely mechanical; arytenoid cartilages which were shifted medially due to the laryngectomy were contacting more medially than normal and thus preventing the neoglottis to close appropriately.
(3) In elderly patients, the perichondrium of the cricoid and arytenoid cartilages becomes thicker, as the formation of cartilaginous fibrillations can be seen on light microscopy.
After the arytenoid cartilage was separated from the cricoid cartilage in the left side, the exoeSL procedure with lower needle at lower edge of thyroid lamina 20 mm from the posterior edge of the thyroid lamina and upper needle at 22 mm from the posterior edge produced a sufficient glottic gap [Figure 3]B.
On strobovideoscopic examination, a solid mass lesion is seen on the left arytenoid cartilage with vocal fold fixation.
The cause of vocal fold immobility can be classified as two different clinical entities: neuropraxia (crush injury) and arytenoid cartilage dislocation.
The mass was hard, and it arose from the arytenoid cartilage. Pathology confirmed that it was a benign chondroma.
Arytenoid dislocations are classified based on the direction of displacement of the arytenoid cartilage. Simple and complex anterior dislocation and simple posterior dislocation have been described previously.
(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.
Vocal process granuloma, also known as contact granuloma (1) or intubation granuloma, is a benign chronic inflammatory lesion that commonly arises from the mucosa overlying the arytenoid cartilage and extending to the posterior one-third of the vocal fold.
We describe the case of a 75-year-old woman with a laryngeal schwannoma that arose from the left postcricoid area and covered the piriform sinus and arytenoid cartilage on that side.
During our evaluation, flexible nasolaryngoscopy detected a keratotic mass on the posterior one-third of the right true vocal fold; the mass extended to the right arytenoid cartilage. The vocal folds were symmetrically mobile.
