Meningioma

A meningioma is a tumor stemming from the covering of the brain, and usually, it is benign. However, a meningioma at the "skull base," the space between the bottom of the brain and underlying skull, can stick to or wrap around vital nerves and blood vessels in this space.

As such, meningiomas in areas such as the cavernous sinus, petous bone, clivus and posterior fossa, require exceptional level of experience and skill to remove. Depending on the location, the approaches that Dr. Jean uses for meningiomas include the orbitozygomatic, petrosectomy, and far-lateral transcondylar approaches.
