Selection of Surgical Approach for Trigonal Meningiomas in Consideration of Visual Outcome.

Objectives: We report the surgical outcome of trigonal meningiomas through 3 different approaches with attention to visual outcomes.

Methods: Between 1994 and 2017, 23 patients underwent resection of trigonal meningiomas. We performed tumor removal using 3 different surgical approaches through the superior parietal lobule, middle temporal gyrus (MTG), and modified MTG.
