Abstract：Objective To investigate the efficacy and safety of surgical treatment for large olfactory groove meningiomas via a unilateral subfrontal approach.Methods The clinical data of 18 patients with large olfactory groove meningiomas were analyzed retrospectively.The largest diameter of the tumor was 4.2-6.6 cm.The microsurgery was performed via the unilateral subfrontal approach.Results The tumor resection was Simpson grade Ⅰ in 4 cases,grade Ⅱ in 13 and grade Ⅲ in 1.There was no death.Cerebrospinal fluid leakage and intracranial infection was observed in 1 case,who recovered well after treatment.All patients were followed up for 6-36 months with a mean period of 14.9 months,and recovered well without recurrence.Conclusion Unilateral subfrontal approach is a safe and effective approach for the treatment of large olfactory groove meningiomas.
