[Meningioma of the posterior cranial fossa]

Within 30 years a total of 60 patients with infratentorial meningiomas have been treated at the Leipzig Neurosurgical clinic: Tentorium 9, cerebellopontine angle 27, Foramen magnum 10, cerebellar hemisphere 13, clivus 1. Case history, clinical data, instrumental diagnostics and change in the therapy are broken down. Present focal points are computer tomography and microsurgery. Both principles have led to a fundamental improvement of morbidity and lethality of these tumour diseases. This tendency has been corroborated by comparisons with the international literature. The individual problems that are dealt with are computer tomography, microtechniques, acusticus and facial nerve functions, vascularisation of the tumours, dural occlusion, the access pathways and the possible postoperative complications.
