Disruption of the endolaryngeal structures including the vocal cord attachments, arytenoid cartilages
and mucosal epithelial lining itself also interfere with laryngeal function.
Mucous membrane and mucoperichondrium covering the medial surface of arytenoid cartilages
and their vocal processes.
The thickening of the aryepiglottic folds and arytenoid cartilages
causes the thumb sign, rather than the epiglottis.
The right arytenoid cartilage
appeared to be in an appropriate anatomic position and at the correct vertical level.
After explanation to the patient of the procedure and airway topicalisation, flexible fibreoptic laryngoscopy was performed, showing anteromedial subluxation of the right arytenoid cartilage
associated with overlying oedema, and slight shortening of the right aryepiglottic fold.
It is assumed that the tracheal tube was impeded by arytenoid cartilage
or epiglottis and then was not passed.
In addition to signs of laryngopharyngeal reflux, strobovideolaryngoscopy revealed a mass along the medial aspect of her left arytenoid cartilage
, mild left paresis, and muscle tension dysphonia.
The anatomical sites at which impingement occurs remain uncertain, with suggested sites including the right arytenoid cartilage
(4), interarytenoid tissue (5) and epiglottis (6).
dislocation is an uncommon entity that is frequently misdiagnosed as vocal fold paresis or paralysis.
5-cm sliver of steel had become impacted in the right cricoarytenoid joint, which made the arytenoid cartilage
unable to rotate.
The edema was located at the aryepiglottic fold; it encompassed the arytenoid cartilage
and false vocal fold, and it extended into the paraglottic space.
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
