Anterior interhemispheric approach for tuberculum sellae meningioma

Abstract

Objective To study the surgical treatment for patients with tuberculum sellae meningioma(TSM) through anterior interhemispheric approach,with special attention to visual outcomes.Methods The clinical data of twenty - one consecutive patients between January 2005 and December 2010were collected.All tumors were removed through anterior interhemispheric approach.The visual acuity and tumor removal were sequentially evaluated in the pre - and post - operative periods.Results Gross total resection (Simpson Ⅱ) was achieved in 19 patients.Among 21patients,15 patients had an improvement of the visual acuity after surgery.The visual acuity was unchanged in 5 patients,and one patients suffered from visual deterioration.The venous infarction of frontal lobe occurred in 2 patients.Conclusions High resection rate and favorable visual outcome support the suitability of this approach for resection of TSM.
