Microsurgical excision of olfactory groove meningioma’s: a brief study of outcome of different surgical approaches

To review the surgical approaches, techniques, outcomes, and recurrence rates in a series of 6 olfactory groove meningioma (OGM) patients operated from January 2010 to April 2011.Methods: Six patients underwent craniotomy and micro-neurosurgical removal of olfactory groove meningioma maximum. Tumor diameter varied from 5 to 8.5 cm among six cases, 2 cases underwent glabellar mini craniotomy another 2 by bifrontal approach and rest of them were by frontolateral approach. Result: Total removal was possible in all cases. Histopathology revealed typical meningioma (WHO grade 1). there was no operative mortality and no permanent focal neurological deficit except anosmia. One patient developed leak and two cases meningitis which was resolved by lumber drain and antibiotic therapy. No tumor recurrence within six months of followup. For the removal of large olfactory groove meningiomas we used three different surgical approaches: frontolateral approaches, bifrontal approach and glabellar mini craniotomy. We consider the frontolateral approach is an alternative, if not superior, to standard bifrontal approaches. DOI: http://dx.doi.org/10.3329/medtoday.v24i1.13942 Medicine TODAY Vol.24(1) 2012 pp.5-7

Olfactory Groove Meningioma

Introduction: To review the surgical approaches, techniques, outcomes and recurrence rates in a series of 11 olfactory groove meningioma (OGM) patients operated from January 2010 to April 2019. Methods: Eleven patients underwent craniotomy and micro-neurosurgical removal of olfactory groove meningioma. Tumor diameter varied from 5 to 8.5 cm among 11 cases, 2 cases underwent Transglabellar/ Subcranial approach, 3 cases by bifrontal approach, 1 case unifrontal approach, 2 extended endonasal and 3 cases fronto-lateral approach. Result: Total removal was possible in all cases except 2 cases. Histopathology revealed typical meningioma (WHO grade 1). There was 1 operative mortality and no permanent focal neurological deficit except anosmia. 3 patients developed CSF leak and two cases meningitis which were resolved by lumber drain and antibiotic therapy. Conclusion: Extended endonasal approach or transglabellar/ subcranial approach were sufficient for gross total removal of OGM which is associated with bony hyperostosis, paranasal extension and optic canal.

Memory Disturbance

Introduction: Meningiomas are the third most common intracranial tumors in adults after glial tumors and metastases. Olfactory groove meningiomas often grow without symptoms due to their slow growth rates and location in the frontal lobe. Optic nerve sheath meningiomas are benign neoplasms of the meninges surrounding the optic nerve. The coexistence of olfactory groove and optic nerve sheath meningiomas without any history of neurofibromatosis or radiotherapy has never been reported in the literature. Case Report: A 36-year-old female patient presenting with anosmia, headache, memory disturbance, and visual impairment and operated with the diagnosis of olfactory groove meningioma was reported. In the postoperative period, optic nerve sheath meningioma was detected in the imaging performed due to the persistence of visual impairment. Conclusion: Olfactory groove and optic nerve sheath meningiomas are rare tumors and can be diagnosed late because they progress slowly. Early diagnosis and treatment may affect the prognosis and morbidity of these patients favorably.

Foster Kennedy Syndrome

Foster Kennedy syndrome is a rare neurological entity that includes ipsilateral optic atrophy, contralateral papilledema, and sometimes anosmia. The syndrome has been described in association with a variety of intracranial pathologies such as a large frontal lobe tumor, olfactory groove meningioma, or medial third sphenoidal wing meningioma. In this report, we present a case of sphenoidal wing meningioma with Foster Kennedy syndrome in a 25-year-old pregnant female.
