Microsurgical management of craniopharyngiomas

A retrospective analysis of 34 patients who underwent microsurgical therapy for craniopharyngioma from 1975 to 1989, a period when CT imaging was routinely used, is presented. Mean follow-up was 6.4 years with no patients lost to follow-up. Those who underwent subtotal resection with adjuvant radiation had a significantly better recurrence-free interval compared with those who either underwent total or subtotal surgical resection only (p < 0.05 and p < 0.025). Among patients treated with surgery alone, the total resection group had a recurrence rate of 20% and those with a subtotal resection 60%. Those with subtotal resection and radiation had a 12% rate of recurrence. Endocrine and visual deficits were common after surgery. Based on this review, our results suggest that with a policy of attempted total resection where possible, subtotal removal along with adjuvant radiation, in cases where total resection was deemed unsafe, may be more effective than aggressive total resection alone as the initial management of craniopharyngioma.
