She subsequently reported to an emergency department, where computed tomography (CT) demonstrated soft-tissue edema without laryngeal pathology or arytenoid cartilage dislocation.
Procedures on arytenoid included extralaryngealarytenoidectomy (4) in which arytenoid cartilage was freed from all its muscular and laryngeal attachments except the vocal muscle.
Furthermore, depending on the length of intubation and other factors, more serious and lasting trauma can result from hematomas, lacerations of the vocal folds, false vocal folds and epiglottis, arytenoid dislocation, granulomas, ulcer, and paralysis of vocal folds.
In patient 4, endoscopic examination revealed a submucosal mass bulging from the posterior wall of the hypopharynx and pushing the right arytenoid cartilage forward without impairing vocal fold mobility (figure 3, A).
These muscles contract to bring the vocal folds together at the midline of the glottis, create medial compression between the vocal folds, and when functioning optimally close the small gap or "chink" that can occur between the arytenoid cartilages in the posterior part of the glottis.
At the 2-week follow-up, the patient reported improved symptoms; however, repeat stroboscopy exhibited persistent, severe redundancy of the posterior arytenoid tissue.
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 first series of tones of the chest register, in which the whole glottis is moved by large, loose vibrations, and the arytenoid cartilages with the vocal ligaments are in action.
If necessary, a variety of surgical corrective options are available, ranging from vocal fold augmentation with injectable fillers or thyroplasty to arytenoid repositioning procedures for selected patients with vocal fold paralysis.
Arytenoid swellings form at the laryngeal inlet, narrowing the slit like aperture.
Physical examination showed bilateral parotid and submandibular swelling, and fiberoptic laryngoscopy showed bilateral swelling of the arytenoid region (figure 1, A).
