In the middle cranial fossa approach for an acoustic tumor, the tumor capsule is debulked and peeled away from the facial nerve. https://t.co/lFCRHj3tvT

During the subtemporal or middle fossa approach, the remaining base of the temporal squama is reduced flush with the floor of the middle fossa. https://t.co/lFCRHj3tvT

During microvascular decompression for trigeminal neuralgia, deeper arachnoid membranes should be dissected free with a fine ball-tip probe to facilitate correct CN identification (top). CN V is deeper and more medial than the VII/VIII complex (bottom).

The lateral paramedian operative corridor provides a more inferior trajectory compared to midline approaches, and is beneficial for accessing the inferior extension of midline and lateral dorsal mesencephalic and pontine tumors.

For skull base tumors, the encasing arachnoid sheath of the nerve is used as a handle to mobilize the nerve away from the tumor capsule using fine forceps. https://t.co/KRUj7c3GyP

During vestibular neurotomy for Menieres disease, the cleavage plane is accessed by using a blunt angled microdissector to separate the vestibular and cochlear divisions. A reasonable plane can often be found.
