[The effect of cryoapplication time using liquid nitrogen for effectiveness of basocellular epithelioma treatment].

Cryosurgery is well suited to treat skin tumors. A cure rate of high percentage is achieved paying attention to freeze time. The course of treatment of 217 basaliomas was analysed. The duration of follow-up after treatment was from 6 to 14 months. 147 lesions were treated with one-cycle cryosurgery. In 64 (45.5%) cases cure was achieved after the first cycle of treatment and in 83 (56.5%) cases the second cycle brought complete healing. 70 basaliomas treated with double freeze-thaw cycle were cured in 100% of cases.
