title: A biorbitofrontobasal interhemispheric approach for suprasellar lesions.
abstract: Suprasellar tumors including pituitary adenomas and craniopharyngiomas, in the case of normofixed or postfixed chiasma and ruptured anterior communicating artery aneurysms in the acute stage, can be approached with minimum brain retraction, increased exposure, and safe manipulation in the shortest possible distance via biorbitofrontobasal interhemispheric approach. Fourteen patients with pituitary adenomas, 3 with craniopharyngiomas, 7 with meningiomas, 2 with mucoceles, 1 with osteoma, and 3 with ruptured anterior communicating aneurysms in the acute stage were operated on, using this approach with excellent results. The operative technique and its results are detailed.
