Abstract
Chronic tonsillitis and benign tumors of the tongue were treated with a Keeler's ENT Cryosurgical Unit utilizing compressed N2O gas. Papilloma and hemangioma in the dorsum of the tongue were frozen in each two cases. The tumors almost disappeared after few months without restriction in movement of the tongue. Four adults with chronic tonsillitis were also treated with cryogenic surgery. Two of them were suffered from purpura and rheumatic heart disease. There was no severe difficulty in oral feeding following the cryosurgery, although a marked edema occurred in the soft palate. The tonsil became atrophic, but some remnants were observed. The hypertrophic tonsil was not indication of the cryosurgery. Cryogenic effects appeared to be limited in the deep tissues. Biopsies after several days of the cryosurgery revealed granulative tissues with hyaline degeneration and fibrin thrombosis.
