Fifty cases of malignant neoplasm of the head and neck were treated with cryosurgery from Sept. 1974 to Sept. 1976 at Kurume University Hospital. In forty cases, 33 primary cases and 7 recurrent cases, cryosurgery was applied for the purpose of erradication of the pathology, whereas, in the other 10 cases, cryosurgery was performed for a palliative purpose. Thirty-eight of forty cases of the former group were followed up for one year or longer. Recurrence was found in tweleve cases. In the latter group, palliative cryosurgery was more or less effective.
In some cases of carcinoma of the maxillary sinus, cryosurgery caused trismus, necrosis of skin, and/or temporary paralysis of eye muscle (s). In the cases of the tongue, pain and/or bleeding was occasionally developed when necrotic tissue was falling off.
