Abstract

Radical removal of extensive tumors in the parasellar region, interpeduncular fossa and cavernous sinus, or the clipping of the distal posterior circulation is very difficult via conventional approach. Seven patients with tumors in the parasella, cavernous sinus and subtemporal area, and six patients with aneurysms of distal posterior circulation were treated by using cranio-orbital zygomatic approach, with good results. The advantages of this approach are minimal brain retraction, exposure of lesion in shortest distance, multidirectional viewing of the lesion and a single cranial bone flap with relative good cosmetic result. Our cases treated via this approach are yet insufficient to compare this approach with other conventional operative approach in definitive advantages but we suggest that this approach is one of the best suitable approach for deep large lesions in the anterior and middle cranial fossae.
