It is suggested that sparing both of the arytenoid cartilages
is beneficial for the rapid recovery of the swallowing function after SCPL (3, 4).
These diarthrodial joints are formed by the articular facets of both the cricoid and arytenoid cartilages
apposed in a multiaxial form.
Then, the CAJ is identified, and the arytenoid cartilage
is separated from the cricoid cartilage or totally removed.
Disruption of the endolaryngeal structures including the vocal cord attachments, arytenoid cartilages
and mucosal epithelial lining itself also interfere with laryngeal function.
Microsuspension laryngoscopy was performed, and a punch biopsy was obtained from the mass on the left arytenoid cartilage
. Pathology was reported as chronic inflammation with no findings of malignancy.
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.
The right arytenoid cartilage
appeared to be in an appropriate anatomic position and at the correct vertical level.
It is assumed that the tracheal tube was impeded by arytenoid cartilage
or epiglottis and then was not passed.
Because all of the muscles that are involved in voice production except one (the cricothyroid muscle) attach to the arytenoid cartilage
, it is important that the arytenoid is mobile within its joint capsule on the cricoid cartilage.
Computed tomography showed that the tumor had encased and distorted the left arytenoid cartilage
and part of the cricoid cartilage and extended to the subglottis.
The anatomical sites at which impingement occurs remain uncertain, with suggested sites including the right arytenoid cartilage
(4), interarytenoid tissue (5) and epiglottis (6).
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.
dislocation is an uncommon entity that is frequently misdiagnosed as vocal fold paresis or paralysis.
Computed tomography revealed that a 2.5-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.
