Effect of freezing the helix and the rim or edge of the human and pig ear.
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.
