#arytenoid

• Arytenoid — Each of the two small, paired, pyramid-shaped cartilages situated at the posterior part of the larynx, above the cricoid cartilage. As an adjective, it describes any structure (muscle, ligament, mucosa) associated with these cartilages. They play an absolutely critical physiological role in phonation and respiration by directly controlling the tension, position, opening, and closing of the vocal cords.
• Arytenoidectomy — A high-precision surgical intervention consisting of the partial or total excision of one or both arytenoid cartilages of the larynx. This structural surgical procedure is primarily performed to treat bilateral vocal cord paralysis in abduction (median position), aiming to widen the restricted glottic space and alleviate severe respiratory insufficiency, thereby restoring a functional airway without completely compromising phonation.
• Arytenoiditis — An acute or chronic inflammatory process localized within one or both arytenoid cartilages or the mucosa covering them in the posterior region of the larynx. This structural condition, often infectious, traumatic, or induced by severe gastroesophageal reflux, manifests clinically through dysphonia (hoarseness), odynophagia (painful swallowing), and an annoying foreign body sensation in the throat.
