Objective: Open craniotomies and nasal approaches are the most common ways to treat olfactory groove meningiomas. However, the supraorbital eyebrow approach has been used in some cases recently. We aimed to evaluate the patients’ surgical outcomes who were treated with the supraorbital eyebrow approach.

Material and Method: We evaluated 17 patients with olfactory groove meningiomas undergoing the supraorbital eyebrow approach from February 2018 to November 2022. A retrospective analysis of patients was performed with eyebrow approaches of our database of 17 who had supraorbital craniotomy for olfactory groove meningioma removal. Patients were evaluated based on pathology, resection rate, complications, and cosmetic re-sults.

Results: Patients\' grade with olfactory groove meningioma was World Health Organization grade 1, and the mean Ki-67 was 1.4. The resection grade was Simpson Grade 1. The satisfaction of patients with cosmetic outcomes was perfect. None of the patients underwent postoperative reoperation. Only one patient underwent rehospitalization in the postoperative period for evaluation due to a suspected wound infection.

Conclusion: Supraorbital eyebrow craniotomy is an effective keyhole approach for the surgery of olfactory groove meningiomas. Future surgical treatment of more types of anterior fossa lesions, with increasing patient numbers and multicenter studies, will employ this technique.
