INDICATIONS, TECHNIQUE AND RESULTS OF THE STEREOTACTIC OPERATIONS UPON THE HYPOPHYSIS USING RADIO-ISOTOPES

Abstract

Based on our experience gained from 104 stereotactic procedures upon the hypophysis, technique and indications are presented. The operations were performed with our own stereotactic apparatus, which is also used for other intracerebral procedures such as pallidotomy, thalamotomy, fornicotomy, etc. Operations on the normal hypophysis (hypophysectomy) or on hypophysial tumors were performed through the transfrontal or the transnasal approach, using varying dosages and forms of radioisotopes for necrobiosis. Postoperative irradiation using stereotactic procedures are dealt with in some detail and the results tabulated. The stereotactic method of operation combines the advantage of low mortality and high tolerance in aged patients or patients who are poor surgical risks.
