Neuroendoscope-assisted Microsurgery through Supraorbital Keyhole Approach for Lesions in Sellar Regions (a Report of 52 Cases)

Objective To explore the experience in treating the lesions of the sellar regions by neuroendoscope-assisted microsurgery through supraorbital keyhole approach and its technique. Method Fifty-two patients with lesions of the sellar regions, of whom, 22 suffered from pituitary adenomas, 15 intracranial aneurysms of anterior circulations, 8 craniopharyngiomas and 7 menin-giomas, were treated by neuroendoscope-assisted microsurgery through supraorbital keyhole approach. Results Of 37 patients with tumors of the sellar regions, 31 received total removal and 6 subtotal or part removal. All the aneurysmal necks were accurately clipped in 15 patients with intracranial aneurysms, of whom, 13 got excellent outcomes and 2 were mildly disabled. The symptoms in all the patients with lesions of sellar regions were improved after the surgery. No patients died of the surgery. Conclusions The lesions in the sellar regions can be exposed well by neuroendoscope-assisted microsurgery through supraorbital keyhole approach. neuroendoscope-assisted microsurgery through supraorbital keyhole approach can reduce the operative injury and complications, and is an effective and safe technique to treat the lesions of the sellar regions.
