1-3) Cricoarytenoid joint space obliteration or clouding can be found in some cases of dislocation.
It refers to partial displacement of the arytenoid within the cricoarytenoid joint, as distinct from arytenoid dislocation, which is complete separation of the arytenoid cartilage from the joint space.
5-cm sliver of steel had become impacted in the right cricoarytenoid joint, which made the arytenoid cartilage unable to rotate.
Its proximity to the contralateral cricoarytenoid joint made the patency of the laryngeal airway after resection uncertain.
LPR has been associated with numerous laryngeal conditions, including muscle tension dysphonia, Reinke's edema, globus pharyngeus, laryngeal hyperirritability, laryngospasm, delayed wound healing, posterior laryngitis, diffuse laryngitis, laryngeal pyogenic granuloma, glottic and subglottic stenosis, cricoarytenoid joint ankylosis, carcinoma, and other conditions.
Cricoarytenoid joint involvement can lead to hoarseness, pain, dysphagia, and vocal fold fixation.
A complete disarticulation of the arytenoid from the cricoarytenoid joint was performed.
By direct laryngoscopy, the cricoarytenoid joint was passively manipulated without restriction, and the dimension of the subglottis was adequate for passage of a 4-mm Hopkins rod telescope.
Four conditions account for nearly all cases of bilateral vocal fold immobility: (1) neurogenic bilateral vocal fold paralysis, (2) cricoarytenoid joint fixation, (3) laryngeal synkinesis, and (4) interarytenoid scar/posterior glottic stenosis.
44] The aim is to pull the muscular process of the arytenoid laterally, reproducing the mechanical effects of the TA and LCA muscles and allowing physiologic motion at the cricoarytenoid joint.
57] Kirchner [56] in 1966 and Gacek and Gacek in 1996 [58] confirmed this phenomenon and showed the absence of cricoarytenoid joint ankylosis, even in protracted paralysis (17 years in one case).
Rotation" of the arytenoid does not and cannot occur physiologically due to the configuration of the cricoarytenoid joint and its ligaments.
