Redundant mucosa was removed from the post-cricoid area and the arytenoids bilaterally.
The specific imaging features of vocal cord paralysis on CT or MRI include atrophy of the thyroarytenoid muscle, anteromedial deviation of the arytenoid cartilage, enlarged laryngeal ventricle, enlarged pyriform sinus, and a paramedian or intermediate vocal cord.
The arytenoid adduction is used if needed to close the back part of the larynx.
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.
Strobovideolaryngoscopy revealed findings consistent with complex posterior arytenoid dislocation (figure 1).
Arytenoid subluxation is a rare laryngeal injury that may follow instrumentation of the airway and present as hoarseness (1), vocal fatigue (1), stridor (2), dysphagia (1), odynophagia (3) and sore throat (1).
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.
The various reasons postulated include impingement on the epiglottis, arytenoid cartilage or pyriform fossae.
Presence of a jostle sign suggests CA joint mobility (passive movement of the arytenoid associated with the paralyzed fold when contacted by the arytenoid of the normal fold during adduction).
The view of the larynx through the airway device aperture was inspected and recorded as follows: grade I = vocal cords fully visible, grade II = vocal cords partially visible, arytenoid cartilages visible, grade III = epiglottis visible, grade IV = no laryngeal structure visible.
