ABSTRACT
Cerebellopontine angle tumors arising anterior to the internal auditory canal and intracranial lesion arishing from the clivus had been considered inferable by many authors. Suboccipital approach to this area using the suboccipital approach is limited because of the retraction of the cerebellum and the brain stem and incomplete exposure. Translabyrinthine approach is also not available due to the facial nerve and cochlea. The transcochlear approach, on the other hand, is not limited to expose not only fifth, seventh, eighth, ninth, tenth, and eleventh cranial nerves, but also the clivus, vertebral arteries, basilar artery, and the contralateral internal auditory canal. Recently we experienced a case of large acoustic neuroma extended to the clivus, and removed it through a transcochlear approach satisfactorily.
