TLDR
A series of 34 meningiomas of the sphenoid ridge is reported, with three postoperative deaths, two cases of hemiparesis with aphasia and epilepsy, one case with a frontal lobe syndrome, and nine with slight oculomotor, visual, or esthetic sequelae.Abstract:
The authors report a series of 34 meningiomas of the sphenoid ridge. Eight tumors were totally removed uneventfully: two from the middle sphenoid ridge and six from the pterion or Sylvian point. Five tumors were not operated on because of their extensions or the patient's age. Twenty-one tumors raised serious surgical problems, resulting in a classification into three groups: deep or clinoidal, invading beyond the sphenoid wings, and a combination of both. Histological study of the hyperostotic bone showed meningiomatous cells in the bone in 12 of 13 cases so examined. Surgical limitations included invasion of the cavernous sinus (15 cases), of the dura mater of the sella turcica (seven cases), of the lateral part of the sphenoid body at the insertion point of the ala magna (seven cases), and of the common tendinous annulus of Zinn in the orbit (five cases), and basilar extracranial extension, particularly in the pterygomaxillary fossa (three cases). Following extensive removal, there were no early recurrences and three late recurrences (9 years and more). In 13 cases with a follow-up period of 1 to 8 years, there were no clinical recurrences. In only two cases was the meningioma totally removed. There were three postoperative deaths, two cases of hemiparesis with aphasia and epilepsy, one case with a frontal lobe syndrome, and nine with slight oculomotor, visual, or esthetic sequelae.read more

Seemingly complete removal of histologically benign intracranial meningioma: late recurrence rate and factors predicting recurrence in 657 patients. A multivariate analysis.
TL;DR: Multivariate analysis showed that coagulation of the dural insertion, invasion of bone, and soft consistency of tumor were strong risk factors for recurrence in meningioma patients with high recurrence rates.

Outcome of aggressive removal of cavernous sinus meningiomas
TL;DR: The rationale for aggressive surgical removal of cavernous sinus meningiomas is based on the presumption that the extent of removal is inversely related to the rate of recurrence, and total removal was achieved in 31 patients.

Hyperostosis Associated with Meningioma of the Cranial Base: Secondary Changes or Tumor Invasion
TL;DR: Results indicate that hyperostosis associated with meningiomas involving the cranial base are caused by tumor invasion of the bone histologically.

TL;DR: In the present study, the superficial and the deep layers of the lateral wall were found to be loosely attached to each other and easy to separate.
