[Late results and consequences of radiotherapy of fibrous dysplasia of the skull].

The paper is concerned with the results of follow-up of 21 patients who were given radiation therapy (gamma-beam and x-ray therapy) for fibrous osteodysplasia of the cranial bones over the period of 1946-1973. The summary focal doses varied from 30 to 100 Gy. Radiation injuries came to the foreground (changes in the skin, radiation cataract, necrosis of the maxillary bones and the development of malignant tumors in two cases). Thus the use of radiation therapy in these cases turned out to be not only ineffective but also unsafe.
