Microsurgical removal of large sphenoidal bone meningiomas.

At the Neurosurgical Department, University Medical Centre of Ljubljana, 10 extirpations of large meningiomas of the sphenoidal wing or tuberculum sellae were done during the period 1975-1978. Microsurgical technique, especially bipolar coagulation, made it possible to remove the tumourous mass from the cerebral tissue, cranial nerves, and arteries of the parasellar region. Out of 10 patients operated on, 2 died. The remainder, i.e. eight patients recovered. Only two showed any neurological signs.
