The previous summer, a singer named Androo O’Hearn, from the band Shaolin Death Squad, had taught the group’s members to tighten their throats so that their aryepiglottic folds—triangular membranes that encircle the larynx and protect it when swallowing—began to vibrate furiously.

Closure of the larynx is accomplished by the approximation of the ventricular bands, arytenoids and aryepiglottic folds, the latter having a sphincter-like action, and by the raising and tilting of the larynx.

Posterior to this the aryepiglottic folds ending posteriorly in the arytenoid eminences are seen in apposition.

Galvanopuncture for laryngeal tuberculosis has yielded excellent results in reducing the large pyriform edematous swellings of the aryepiglottic folds when ulceration has not yet developed.

The upper edges of the aryepiglottic folds are approximated, leaving a narrow chink.
