[TA]
the synovial joint between the base of each arytenoid cartilage and the upper border of the lamina of the cricoid cartilage.

Upper airway manifestations include rheumatoid nodules on the vocal cords, vasculitis affecting the recurrent laryngeal or vagus nerve leading to vocal cord paralysis, or arthritis of the cricoarytenoid joint. Lower airway disease may include bronchial hyperresponsiveness, bronchiolitis or bronchiectasis.
Additional work is needed to clarify the rotational dynamics of the arytenoid cartilage and cricoarytenoid joint and to develop techniques with abilities to measure movements in this region objectively.
We conclude that CT can be useful for assessing radiologic changes in the cricoarytenoid joint in elderly patients during the workup of dysphonia and abnormal movement of the vocal folds.
proposed this procedure in 1984.[2] Endoscopic laser surgery had commonly been used but could result in the formation of granulation tissue leading to renarrowing of the airway or excessive enlargement of the glottic lumen which was irreversible.[3] Most of the laser surgery actually ablated partial arytenoid cartilage, large proportion of vocal ligament, and the thyroarytenoid (TA) muscle to achieve enlargement of the glottic lumen.[3],[4],[5] The cricoarytenoid joint (CAJ) and CAJ fixation (CAJF) were often developed after the first session of laser surgery.
Laryngeal involvement with cricoarytenoid joint alterations can be found in rheumatoid arthritis, ankylosing spondylitis, and gout.
Arthritis of the cricoarytenoid joint is rare but it deserves attention as the clinical spectrum ranges from mild dysphagia, throat pain, or dyspnea upon exertion to sudden glottic stenosis, stridor, and acute respiratory failure requiring immediate surgical treatment [13-15].
(20) This should be distinguished from cricoarytenoid joint luxations, which are characterized by displacement (anterior, medial, posterior, etc.) of the arytenoid cartilage, often with accompanying rotation or tilting of the cartilage with respect to the cricoid.
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.
Much has been learned recently about the basic but complex function of structures such as the cricoarytenoid joint, for example.
If the patient is not treated early laryngeal TB can result in subglottic stenosis, muscular involvement and vocal cord paralysis when the cricoarytenoid joint or recurrent laryngeal nerves are invaded.
Persistent vocal fold limitation in the median position with cricoarytenoid joint fixation was still noted after 1 month; however, the patient complained of neither hoarseness nor choking.
Result: Inappropriate size or location of the implant material were defined in two subjects, inappropriate management of the inner perichondrium of thyroid lamina (IPTL) were defined in 5, and cricoarytenoid joint (CAJ) fixation in one.
