Radical excision of craniopharyngioma by the temporal route: A review of 50 patients

Abstract

Attempts at radical excision of craniopharyngioma have been made increasingly possible by progress in neuroradiological imaging and the use of microscopic technique. Between 1977 and 1990, 50 patients of The National Hospital for Neurology and Neurosurgery, London, have undergone radical surgical excision of craniopharyngioma by the temporal route, with a small anterior temporal resection. Surgical mortality was 4%. Thirty-eight (76%) patients remain well at average follow-up of 30 months; 15% had major complications (hypothalamic damage, subdural haematoma, scalp collections requiring shunt drainage). There were three recurrences in those patients where the initial operations were considered as complete microscopic excision. It is concluded that maximal control of tumour recurrence by removal of all tumour accessible and visible to the surgical microscope is best achieved by a radical excision at the first operation.
