Abstract

Objective: Retrospective analysis of the clinical, radiological presentation, surgery and outcome following management of OGMs at our institute over a eleven year period
Materials and Methods: A total of 28 cases operated for olfactory groove meningioma at the Department of Neurosurgery, National Institute of Mental Health And Neurosciences, Bangalore over a 11 year period were analyzed for clinical and radiological presentation, detailed study of operative notes for surgical approaches, neuro-radiological evaluation, follow-up examination, and histopathology slides.
Results: Twenty eight patients underwent surgery for olfactory groove meningiomas. The mean and median ages of the patient were 49 and 49.5 years respectively (range32-71 years). Of these 7 were male and 21 female patients. Headache was the most frequent presenting symptom seen in 21 cases (75%) Bifrontal craniotomy was the predominant approach used in 25 cases(89%), unilateral frontal craniotomy in 1 cases(%) and pterional in 2 case (7%). Post-operative complications seen were seizures, CSF rhinorrhoea, post-operative frontal hematoma which required re exploration and evacuation of hematoma.
Conclusion: It is important for the psychiatrist to be aware of olfactory groove meningiomas as majority of them present with neuropsychiatric manifestations for early detection of these tumours as safe surgical excision with low mortality and morbidity can be obtained in these tumours despite their large size at presentation.
