[202] Angiomata, if extensive and deeply seated, may require deep excision, but usually cure results from superficial removal. Usually no cauterization of the vessels at the base is necessary, either to arrest hemorrhage or to lessen the tendency to recurrence. A diffuse telangiectasis, should it require treatment, may be gently touched with a needle-pointed galvanocaustic electrode at a number of sittings. The galvanonocautery is a dangerous method to use in the larynx. Radium offers the best results in this latter form of angioma, applied either internally or to the neck. _Lymphoma, enchondroma and osteoma_, if not too extensively involving the laryngeal walls, may be excised with basket punch forceps, but lymphoma is probably better treated by radium.* _True myxomata and lipomata_ are very rare. _Amyloid tumors_ are occasionally met with, and are very resistant to treatment. _Aberrant thyroid tumors_ do not require very radical excision of normal base, but should be removed as completely as possible. In a general way, it may be stated that with benign growths in the larynx the best functional results are obtained by superficial rather than radical, deep extirpation, remembering that it is easier to remove tissue than to replace it, and that cicatrices impair or ruin the voice and may cause stenosis. * In a case reported by Delavan a complete cure with perfect restoration of voice resulted from radium after I had failed to cure by operative methods.

[203] CHAPTER XXII--BENIGN GROWTHS IN THE LARYNX (Continued) PAPILLOMATA OF THE LARYNX IN CHILDREN Of all benign growths in the larynx papilloma is the most frequent. It may occur at any age of childhood and may even be congenital. The outstanding fact which necessarily influences our treatment is the tendency to recurrences, followed eventually in practically all cases by a tendency to disappearance. In the author's opinion multiple papillomata constitute a benign, self-limited disease. There are two classes of cases. 1. Those in which the growth gets well spontaneously, or with slight treatment, surgically or otherwise; and, 2, those not readily amenable to any form of treatment, recurrences appearing persistently at the old sites, and in entirely new locations. In the author's opinion these two classes of case represent not two different kinds of growths, but stages in the disease. Those that get well after a single removal are near the end of the disease. Papillomata are of inflammatory origin and are not true neoplasms in the strictest sense.
