[Surgical treatment of meningiomas of the posterior surface of the pyramid of the temporal bone].

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.
