In particular, the use of multiplanar reformats and 3D volume renderings, with or without virtual endoscopy, can improve assessment of laryngeal framework fractures, arytenoid subluxation, and laryngotracheal narrowing, thereby providing helpful information for optimal management.
Arytenoid subluxation was seen in 2 males and 1 female.
In our study, among the patients who underwent 10-15 days intubation, 3 had epiglottis ulcer, vocal cord scar, arytenoid subluxation and arytenoid granulation are seen in 2 patients each.
Above data shows 5 patients had vocal cord granulomas, which is the most frequent lesion encountered; 4 patients had interarytenoid adhesion which is the next common lesion followed by vocal cord scarring, web formation, arytenoid subluxation and epiglottic ulceration in 3 patients each.

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).
A differential diagnosis of airway oedema, laryngospasm, vocal cord paresis and arytenoid subluxation was entertained.
A MeDLINe search of all cases to date using the search terms "arytenoid subluxation" and "arytenoid dislocation" identified fewer than 80 cases, although the true incidence is probably under-reported owing to misdiagnosis as vocal cord paresis.
Patients with arytenoid subluxation primarily report hoarseness upon presentation (1,8.) Vocal fatigue, inability to project the voice and stridor are also common symptoms.
