The authors examined 162 patients with meningiomas of the posterior surface of the pyramid of the temporal bone. The difficulty of surgical removal of meningiomas is associated with the difficult access to them, their closeness to the stem parts of the brain, and their direct connection with the cranial nerves and the vessels of the vertebrobasilar system. Since the meningiomas are located mainly within the limits of the pontocerebellar angle, the paramedian approach is the most adequate one. Microsurgical removal of meningiomas was carried out in 54 patients.

The data of 153 operations and 38 autopsies were used to study the microtopographoanatomical relationships of structures of the cerebellopontile angle in meningiomas of the posterior surface of the pyramid of the temporal bone. The details of the microtopography of the structures of the cerebellopontile angle were studied on 6 block-specimens with meningiomas and during 20 operations by means of an operating microscope. The authors revealed variants of the relationship of the cerebellopontile angle structures with the tumors depending on the site and direction of their growth.
