 Posterior Fossa Craniotomy for Brain Tumors

Posterior Fossa Craniotomy for Brain Tumors 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. If a tumor grows there it can block the flow of cerebrospinal fluid and can put pressure on the cerebellum, the brain stem or upper spinal cord. This may cause severe headaches in the back of the head. The pressure can also cause weakness, upset stomach, paralysis, numbness and problems with the bowels or bladder. Damage to nerves from the tumor can cause problems with the muscles of the face, hearing and vision. Balance may also be negatively affected. After the surgery, it may take a long time to recover from the weakness and symptoms that you had prior to the operation. It is important to follow a strict physical therapy program to help regain strength.
