[Topographoanatomic prerequisites for radical surgery of craniopharyngiomas]. | Sixty-seven patients with craniopharyngioma were tested by total (41) or subtotal (26) resection of the tumor. The possibility for radical removal of a craniopharyngioma depends on the size of the tumor and the character of its growth and on the peculiarities of its relation with the abjoining structures, i.e. the sell... | 654,186 | [
