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

Patients with olfactory groove meningiomas may present with anosmia. Surger y in patients with intact olfaction can also lead to anosmia when the olfac tory nerves are sacrificed. Olfaction can be preserved by using the pterion al approach and microsurgical technique.(1) To our knowledge, however, the recovery of olfaction after resection of an olfactory groove meningioma has not been reported. We therefore describe a patient who presented with anos mia whose evaluation revealed a large olfactory groove meningioma. She unde rwent a bifrontal approach for microsurgical gross bilateral excision of th e tumor. At her 6-month follow-up examination, her olfaction, as measured b y formal testing, had recovered.
