Retrosigmoid Suprameatal Transtentorial Approach for Petroclival Meningioma: Maximizing Retrosigmoid Corridor

We describe our experience with a 74-year-old male with weakness, ataxia, and CN 7/8 deficits; MRI demonstrated a large right-sided petrous-tentorial meningioma. The right retrosigmoid suprameatal transtentorial approach was performed with near-total resection. Postoperatively, ataxia improved but he developed internuclear ophthalmoplegia (learning point in the video about handling perimesencephalic venous bleeding) which resolved in subsequent follow-up at 1 year. In addition, we discuss technical nuances of maximizing retrosigmoid corridors.
