Current results of nitrogen cryotherapy in eyelid basaliomas

Abstract

By means of long-term follow-ups of large numbers of patients it has been established that nitrogen cryotherapy for lid basaliomas produces very good results with regard to the cure rate, as well as having considerable advantages over other treatment methods. In contrast to other authors we did not employ the spray method, but a very high-performance nitrogen cryo unit with a closed probe. Experimental measurements showed that this unit is capable of generating at least the same temperatures as with the spray method. The cryoapplication technique is described. The cure rate and causes of recurrence in the first series in the total of 84 patients treated from 1979 to 1983 were evaluated by long-term follow-up. If cryobiological principles are observed and the recommended application technique is adhered to, the same cure rate can be achieved as with the spray method and other forms of treatment. There are considerable functional and cosmetic advantages, also as regards the patency of the lacrimal ducts.
