Preoperative Detection of the Facial Nerve Location Using Balanced Fast Field Echo and Diffusion Tensor Imaging in Patients with Large Cerebellopontine Angle Tumors

Abstract

Objective: Facial nerve preservation is an important issue in surgery of large cerebellopontine angle (CPA) tumors. We tried to predict the location of facial nerve in large CPA tumors using 3-tesla MRI, and verified by intraoperative findings.
