SINCE my interest in cryogenic applications to otolaryngology began in 1963, I have gained the most experience with cryotonsillectomy.1,2 Forty-six adults underwent cryosurgery from 1964 to February 1966. In an effort to present long-term results, I have not included in this report the 120 patients treated by my colleagues and myself since that time. The patients were generally from the East Coast, but a few were from the Midwest.

Materials and Methods  The Cooper-Linde cryosurgical unit supplied by liquid nitrogen was initially used. The last patients undergoing therapy were treated with Hill-Frigitronics unit using a liquid refrigerant (Freon). There was no apparent difference in the overall clinical response between the two units.Adult volunteers had each tonsil frozen for five minutes at —196 C with the Cooper unit and for the same time at —60 C with the Hill Unit. In late 1965 two applications of five minutes each
