[Clinical experience with cryotherapy of lid tumors (author's transl)].

Eleven patients with lid tumors underwent cryotherapy. Of these, six suffered recurrence of the tumor following surgery or radiotherapy, respectively. The patients' average age was 66.1 years. The temperatures required for cryotherapy were obtained with fluid nitrogen. Two possible modes of treatment may be distinguished. In contact freezing (used in eight cases) the cryoapplicator is in direct contact with the surface of the tumor. In the second method, spray-freezing (used in three cases), fluid nitrogen is sprayed at a certain pressure directly on to the surface of the tumor. In all cases treatment was performed on outpatient basis. The indications for treatment, the technique applied and the results obtained hitherto are presented.
