We recorded impingement at the right arytenoid
, left arytenoid
, epiglottis, interarytenoid tissue and the left pyriform fossa.
The right arytenoid
cartilage appeared to be in an appropriate anatomic position and at the correct vertical level.
After the resection of the arytenoid
the surgical site is covered with neurosurgical cottonoid with 2ml of mitomycin (1mg/ml) for 2 minutes to prevent fibrosis.
The redundancy was much worse on the left, and the tissue in the arytenoids
region prolapsed into the glottis.
The first series of the falsetto register, where again the whole glottis, consisting of arytenoid
cartilages and vocal ligaments, is in action, the very fine interior edges of the ligaments, however, being alone in vibrating motion.
Physical examination showed bilateral parotid and submandibular swelling, and fiberoptic laryngoscopy showed pharyngolaryngeal edema and edema of the epiglottis, vallecula, and the right arytenoid
region (figure 1, B).
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.
shows caudo-cranial order of maturity.
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.
Strobovideolaryngoscopy revealed findings consistent with complex posterior arytenoid
dislocation (figure 1).
Indirect laryngoscopy revealed right vocal cord palsy and edema of vocal cords involving arytenoid
5-cm sliver of steel had become impacted in the right cricoarytenoid joint, which made the arytenoid
cartilage unable to rotate.
In some individuals, the placement of the endotracheal tube can result in injury to a vocal fold or even dislocation of the arytenoid
cartilage off its location on the cricoid cartilage.
The edema was located at the aryepiglottic fold; it encompassed the arytenoid
cartilage and false vocal fold, and it extended into the paraglottic space.
MTP III, also a supraglottic muscle tension, is characterized by an anteroposterior shortening of the distance between the epiglottic petiole and the arytenoid
muscles secondary to contraction of the larynx during phonation.
