We have studied the effect of increasing freeze times on the normal pig's ear and on a variety of lesions of the human ear. The clinical and laboratory data suggest that cartilage necrosis secondary to cryosurgery is a dose-related phenomenon and is uncommon with the freeze times used in clinical practice. Cryosurgery is an effective and cosmetically acceptable treatment for superficial skin lesions of the ear.
