“…The movement of the arytenoids has been characterized as an anteroposterior rocking over the long axis of the arytenoids, a lateromedial gliding and a lesser degree of rotation [1][2][3] . It has also been characterized as a revolving or pitch-like motion.…”

Objectives: To look at the incidence of arytenoid asymmetry in a group of healthy singers and to investigate whether the asymmetry correlates with posture, neck tension and glottal attack. Materials and Method: The medical records and video recordings of 42 singers were reviewed retrospectively. Posture, neck tension and glottal attack were evaluated in relation to arytenoid asymmetry during adduction. Results: The number of singers was 42, with a male-to-female ratio of 2:1. The age range was 16–38 years, with a mean of 24 ± 4.13 years. The total prevalence of arytenoid asymmetry was 50%, with a predominance in males and on the right side. The most common asymmetry was that of the cuneiform cartilages, accounting for 40.5% of the total sample and 81% of the total asymmetries. There was no correlation between arytenoid asymmetry and either posture, neck tension or glottal attack (p = 0.343, 0.489 and 0.945, respectively). Conclusion: One out of 2 singers is likely to have arytenoid asymmetry during adduction. The presence of asymmetry does not correlate with posture, neck tension or glottal attack.

“…The joint controls abduction and adduction of the vocal cords thereby facilitating respiration, as well as protecting the airway and permitting phonation. 9,14 Any synovial articulation can potentially be affected by rheumatoid arthritis. Increased cellularity of the synovium occurs leading to synovial inflammation.…”

P Pu ur rp po os se e: : To report acute upper airway obstruction due to cricoarytenoid arthritis, a well known but uncommon complication of rheumatoid arthritis.C Cl li in ni ic ca al l f fe ea at tu ur re es s: : We report the case of a 70-yr-old female scheduled for a colostomy who had been suffering from rheumatoid arthritis for 17 years. Preoperative history and physical examination revealed no cardiopulmonary compromise. Anesthesia was induced while an assistant immobilized the cervical spine and an atraumatic intubation was performed. Surgery was uneventful.Muscle paralysis was reversed, demonstrated by normalization of the train-of-four response, and the patient was extubated awake. Shortly postextubation, the patient developed inspiratory stridor, which disappeared after a second dose of neostigmine. The patient was transported to the postanesthesia care unit. Just prior to arrival the patient once again developed inspiratory stridor, became distressed, and oxygen saturation decreased. Direct laryngoscopy followed by a nasal fibreoptic examination of the larynx was performed. Cricoarytenoid arthritis secondary to rheumatoid arthritis with airway compromise was diagnosed. An uneventful awake tracheostomy was performed. The patient was discharged on day ten with a colostomy and a tracheostomy in place. One month postdischarge the patient's trachea was decannulated. On follow-up, a normal voice and mobile cords were observed. C Co on nc cl lu us si io on n: : Cricoarytenoid arthritis is an infrequent complication of rheumatoid arthritis. A thorough history and physical examination are necessary to recognize signs and symptoms of cricoarytenoid arthritis. Prompt recognition of airway obstruction due to cricoarytenoid arthritis is essential for appropriate management. NESTHESIOLOGISTS frequently care for patients with rheumatoid disease. Any synovial surface in the body can be affected and females are in the majority. [1][2][3] Comprehensive assessment of the potential hazards facilitates careful anesthetic management. [2][3][4] We report a case of acute upper airway obstruction due to cricoarytenoid arthritis, a well-known but rare complication of rheumatoid arthritis.

“…The q axis is taken perpendicular to both the / and m axes and is directed so th a t the / m q coordinate system is right handed, th a t is, the q axis is directed from a medial, anterior, and inferior direction to a lateral, posterior, and superior direction ( Figure 5). As discussed by Sonesson [3] and by von Leden and Moore [1], the cricoarytenoid joint has two m ajor degrees of freedom which are determined by the geometry of the articular interface. These are illustrated in Figure 6 in which the cartilages are seen from two different oblique views.…”

“…For this the mechanical constraints of the laryngeal cartilage system should be considered in order to understand how the cartilage movements are manifested in the laryngoscopic view and, conversely, to understand how laryngoscopically observed changes are to be inter preted in term s of the three-dimensional movements of the cartilages. The need for such a consideration was emphasized in a study by von Leden and Moore [1] in which it was shown how an understanding of the mechanics of the cricoarytenoid joint was basic to a correct interpretation of laryugoscopically observed motions of the arytenoid cartilages. It appears th a t mechanical concepts might be employed for the laryngoscopic interpretation of the movements of a yet more extensive portion of the laryngeal cartilage system which would include not only the arytenoid cartilages, but the thyroid and cricoid cartilages as well.…”
