Objective: Olfactory groove meningiomas arise in the midline along the dura of the cribiform plate and may achieve a large size before producing symptoms. We conducted a retrospective study of patients with these lesions focused in pre- and postoperative tests for ophthalmologic, personality and cognitive disturbances.
Methods: The authors reviewed 36 cases of giant olfactory groove meningiomas surgically treated via bifrontal approach. Ophthalmologic evaluation included visual acuity, fundoscopy and visual field. While psychiatric evaluation included Mini-Mental State Examination. Data were collected before, 1 month and 12 months after surgery.
Results: Formal pre- and postoperative ophthalmologic examinations discovered visual deficits in 55.5% of the patients. Within the first month after surgery, improvement of visual acuity and of visual field deficits was observed. In postoperative neuropsychological testing, higher mental functions showed improvement. The most frequent postoperative complication was persistent rhinorrhea in 2 patients.
Conclusions: Although this is not a comparative study, the ophthalmologic and neuropsychological results at longest follow-up indicate that the bifrontal approach may be the preferred option or the surgery of giant olfactory groove meningiomas.
