Posterior Fossa Craniotomy

The operation to remove a brain tumor located near the bottom of the skull is known as Posterior Fossa Craniotomy and Tumor removal. The goal of the surgery is to remove the tumor and get rid of the pressure on the cerebellum, spinal cord, and brain stem. The cerebellum is the smaller part of the brain that is important for balance and coordination, and it is located in the lower part of the skull in an area known as the posterior fossa.
