Study on microsurgical treatment by unilateral subfrontal approach in 16 patients with large olfactory groove meningiomas

Abstract

Objective To study the method and therapeutic effect of microsurgical treatment by unilateral subfrontal approach in patients with large olfactory groove meningiomas. Methods The clinical data of 16 patients with large olfactory groove meningiomas who had underwent microsurgical treatment by unilateral subfrontal approach from January 2010 to December 2017 were analyzed retrospectively. Results Total removal of tumor (Simpson Ⅰ and Ⅱ grade) was achieved in 14 cases and subtotal removal of the tumor (Simpson Ⅲ) was in 2 cases. No patient died from the microsurgery. The treatment effect was satisfactory in all patients during the follow-up. Conclusions The microsurgical treatment by unilateral subfrontal approach in patients with large olfactory groove meningiomas conforms to the concept of minimal invasive surgery, which provides enough surgical space, and the effect of surgery is satisfactory. So the approach is a good choice for the removal of large olfactory groove meningiomas. Key words: Meningioma; Microsurgery; Unilateral subfrontal approach
