Resection of the anterior part of pyramid through the middle fossa craniotomy will give us a surgical field of the parasellar, clivus and cerebellopontine angle without sacrificing the auditory structure. The advantage of the anterior transpetrosal approach is the direct access to tumors that attached to the clivus via a keyhole created on the petrosus apex. Bloodless tumor removal can be achieved by detachment of the tentorial artery and direct access of the anterior internal auditory canal also can minimize the injury of the cranial nerve facialis and vestibulocochlearis. Another advantage is the low risk of venous damages since this approach is not exposing the sigmoid sinus and the vein of Labbe.
