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.
Hoarseness after laryngeal blunt trauma: A differential diagnosis between an injury to the external branch of the superior laryngeal nerve and an arytenoid subluxation
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 prospective study suggested an incidence of one arytenoid subluxation or less for every 1000 direct laryngoscopic intubations (0.
Patients with arytenoid subluxation primarily report hoarseness upon presentation (1,8.
after a difficult intubation treated successfully with voice therapy.
Utility of helical computed tomography in the study of arytenoid dislocation and arytenoid subluxation
