Children sometimes entertain themselves with this vocal novelty, but it is put to serious use by people who have experienced laryngotomy.

C�lius Aurelianus recognized diphtheria of the pharynx and larynx, as well as the diphtheritic paralysis of the soft palate; it is to him we are indebted for the information that Asclepiades resorted to scarification of the tonsils, and even to laryngotomy.

Aret�us of Cappadocia is notably the first, if we except Asclepiades only, who is said to have performed laryngotomy.

Treatment.—If the symptoms are urgent, laryngotomy, which consists in opening the larynx below the glottis by dividing the crico-thyreoid membrane, or tracheotomy must be performed at once, and an attempt made to remove the foreign body thereafter.

If it is found impossible to remove the body through the mouth, laryngotomy or tracheotomy should be performed, and the body extracted through the wound, or pushed up into the pharynx and removed by this route.
