Abstract
Olfactory groove meningiomas (OGM) account for 4.5% of all intracranial meningiomas.
We report 21 patients with OGMs. Tumors were operated on using three surgical approaches:
bifrontal (7 patients), fronto-pterional (11 patients) and fronto-orbital (3 patients).
Total tumor removal (Simpson Grade 1) was achieved in 13 patients and Simpson II in
8 patients. Perioperative mortality was 4.76%. The average size of the OGM was 4.3 ± 1.1 cm. The overall recurrence rate was 19%. We preferred to use the pterional approach,
which provides quick access to the tumor with less brain exposure. It also allows
complete drainage of cisternal cerebrospinal fluid, providing a good level of brain
relaxation during surgery. However, for long, thin tumors, hemostasis can be difficult
using this approach.
