Figure 2: (a) Intraoperative image of facial nerve under the microscope. (b) Bony structure of cranial base was removed to expose C2 segment of internal carotid artery at superior border of the tumor body. (c) Anatomic relationship between C2 and adjacent facial nerve (white arrow) after removal of mastoid and styloid. (d) Prereconstruction cervical-to-petrous internal carotid artery in situ bypass surrounding the lesion. The external auditory canal (white arrow) was cut and put back at the end of the operation
