Return of olfaction after gross total resection of an olfactory groove meningioma: case report.

Patients with olfactory, groove meningiomas may present with anostnia, Surgery in patients with intact olfaction can also lead to anosmia when the olfactory nerves are sacrified. Olfaction can be preserved by using the prerional approach and microsurgical technique. To our knowledge; however, the recovery of olfaction after resection of an olfactory groove meningroma has not been reported. We therefore describe a patient who presented with anosmia whose evaluation revealed a large olfactory groove meningioma. She underwent a bifrontal approach for microsurgical gross bilateral excision of the tumor. At her 6-month follow-up examination, her olfaction, as measured by formal testing, had recovered.
