FLOOR OF FRONTAL FOSSA MENINGIOMAS
(Meningioma Management, File 8)
These meningiomas arise from the dura
over the orbital roof and compress and/or cause edema in the adjacent
frontal lobe. The diagnosis is established by MRI. Angiography is
not needed. The indications for operation are headache or frontal
lobe symptoms. Radiation therapy has not been used.
A subfrontal approach is used. The
key considerations in the operation are the same as outlined for
meningiomas in general. (see File
In the two cases in my series the
indication for treatment was persistent headache. Both were women,
of age 51 and 63 years. A total removal was done and both resumed
their preoperative level of activity. There has been no recurrence.
