Introduction: Removal of intracranial supra-sellar masses continues to be a surgical challenge. Various approaches have been used by different authors with varying results. Anterior basal interhemispheric approach is most suitable with better results than other approaches for craniopharyngiomas

Materials and methods: Fifteen patients with large craniopharyngiomas having third ventricular and or retro or supra-sellar extensions or reaching the interpeduncular cisterns were operated by this approach, over a period of seven years since the first use of this approach at our institute. The data of patients opearated by this approach were then retrospectively analysed. There were eleven males and four females with five patients in the pediatric age group. Follow up range was from 2 to 83 months with a mean of 21.6 months.

Results: Total excision was achieved in seven (46.6%) and near total excision in another seven (46.6%), partial excision was done in only one (6.66%). Seven patients with total excision were disease free at mean follow up of 6.8 months. There was asymptomatic recurrence in two (13.33%) patient with near total excision at 11 and 63 months respectively and were given radiotherapy post-operatively. All patients were symptom free except one with diabetes insipidus (DI) and one mortality, and one with post operative visual deterioration.

Conclusion: Anterior basal interhemispheric approach is a useful alternative to other transcranial approaches in the management of the craniopharyngiomas. It has the advantage of being a midline approach and displays the tumour brain interface better.
