#airway

• ABC (Airway, Breathing, Circulation) — A fundamental medical acronym used in cardiopulmonary resuscitation (CPR) and first aid protocols, standing for the critical steps of primary assessment and intervention: A (Airway), B (Breathing), and C (Circulation). While modern cardiac arrest guidelines often use the CAB sequence, ABC remains the cornerstone for primary trauma assessment.
• 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.
