Craniotomy and Brain Tumor Resection

A Craniotomy is the surgical procedure that entails the removing a small portion of the bone from the skull to expose the brain. Small surgical tools are used to remove a portion of skull known as the bone flap. The bone flap is reattached after the surgery is completed. Craniotomy procedures also utilize computer guided imagery (called intraoperative monitoring) to ensure the exact location within the brain that needs to be treated. This technique also uses a frame placed onto the skull or a frameless system using markers placed on the scalp. When these techniques are used along with the Craniotomy procedure, it is called Stereotactic Craniotomy.

Scans made of the brain, in conjunction with these computers and the specialized frames, create a 3D image of the brain and the tumor that needs to be removed. This allows surgeons to differentiate between affected brain tissue and healthy brain tissue.

Many of these procedures are performed through a small incision and with the use of small scopes and surgical cameras. This procedure is known as an Endoscopic Craniotomy. This approach minimizes the amount of bone needed to be removed as well as minimized the damage to the surrounding brain tissue. Endoscopic Craniotomy may also be used for tumors seeper in the brain that would require significant dissection during surgery.

The Neurosurgical Team at Metropolitan Neurosurgery Associates are pioneers in Endoscopic Craniotomy and Stereotactic Craniotomy procedures and have treated patients from across the country with this innovative approach.
