  ABSTRACT: Objective: Many approaches have been used for surgical removal of olfactory groove meningioma (OGM) as pterional, bifrontal, interhemispheric, and frontolateral approach. We evaluated the role of unilateral subfrontal approach for the removal of giant OGM “bigger than 6-cm”. Patients and Methods: Nine patients with giant OGM had unilateral subfrontal approach between 1st of January 2015 and December 2017 in Cairo University Hospitals. A retrospective study we done analyzing clinical data, neuroimaging, surgical result and extent of tumor resection. Results: Total tumor resection was achieved in seven cases “Simpson grade I and II”. Subtotal resection was achieved in two cases, one case there was enchasing of the anterior cerebral artery. The other case subtotal resection was achieved due to old age of the patient. The frontal air sinus and cribriform plate and ethmoidal sinus were repaired using fat, fascia lata and vascularized pericranium flab with the use of histoacryl: One case developed hydrocephalus which required the insertion of a ventriculo-peritoneal shunt. One case developed wound infection and meningitis which required medical treatment only. There is no case of CSF leak or mortality in our series. Conclusion: The unilateral subfrontal approach is a safe and efficient approach for removal of giant olfactory groove meningioma. It combines the benefits of the bifrontal, frontolateral and pterional approach with early access to CSF drainage and early attack of the blood supply of the tumor.
