Eagle syndrome

Common card · No. 203898

Eagle syndrome (also termed stylohyoid syndrome, styloid syndrome, stylalgia, styloid-stylohyoid syndrome, or styloid–carotid artery syndrome) is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck. First described by American otorhinolaryngologist Watt Weems Eagle in 1937, the condition is caused by an elongated or misshapen styloid process (the slender, pointed piece of bone just below the ear) and/or calcification of the stylohyoid ligament, either of which interferes with the functioning of neighboring regions in the body, such as the glossopharyngeal nerve.
