[Clinical and surgical aspects of meningiomas of the base of the skull. 1. Meningiomas of the anterior fossa].
OBJECTIVE
Meningiomas are usually benign, slow growing tumours. They form around 15% of all intracranial tumours and approximately a third are found at the base of the skull. In this paper we describe the clinical and surgical characteristics of meningiomas of the anterior fossa and our experience in treating them surgically.


METHODS
We present 25 patients who were operated on for meningiomas of the olfactory sulcus, orbit and sella and suprasella meningiomas, and the results obtained.


CONCLUSIONS
The results showed: 1. Female predominance at all sites. 2. Age did not determine whether surgery was performed. 3. In most cases macroscopically complete resection of the tumour was achieved. 4. The size of the tumour worsened the preoperative clinical situation and postoperative morbidity and mortality.
