Eric Marvin, MDCranial and Skull Base Neurosurgery"Developing relationships with my patients and seeing them satisfied with their surgical outcomes is absolutely the reason why I got into neurosurgery. "

A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The purpose of the procedure is to remove a brain tumor or a sample of brain tissue. It may also be done to remove blood or blood clots from the brain, relieve pressure in the brain after an injury or stroke, repair a skull fracture or brain aneurysm (a bulge in a blood vessel wall), or treat other brain conditions. The bone flap is replaced after the brain surgery has been done.

Endoscopic surgery is minimally-invasive, meaning it does usually not require a large incision. Neurosurgeons may make a small opening inside the nose to remove a growth through a thin lighted tube called an endoscope. An MRI is a type of picture taken of the skull base using magnets and a computer and may be done by a radiology specialist while the surgical specialists are operating to help them make sure all of the growth has been removed.

This is the most common way to remove pituitary tumors. Transsphenoidal surgery is done through the sphenoid sinus, a hollow space in the skull behind the nasal passages and below the brain. The back wall of the sinus is just below the pituitary gland.

This minimally invasive surgical tool removes hematomas with low tissue disruption, protecting parts of your brain that control speech, memory and vision. The neurosurgeon is able to navigate between the natural folds in the brain and map the exact location of the tumor or blood clot using imaging. Then, through an opening no larger than a dime, the neurosurgeon can remove the clot or tumor from the deepest recesses of the brain without cutting or damaging anything else in its path.

CyberKnife uses stereotactic body radiation therapy, delivering precise doses of radiation with extreme accuracy—accounting for tumor or patient movement in real-time. The robot moves and bends around the patient to deliver radiation doses from thousands of unique beam angles, significantly expanding the possible positions to concentrate radiation to the tumor while minimizing dose to surrounding healthy tissue.

Neurosurgeons work closely with interventional radiologists, neurologists, oncologists and staff. Specialists contribute expertise in brain anatomy, skull base pathology, imaging, neurological function and oncological considerations. A collaborative effort ensures comprehensive patient evaluation, precise surgical planning, and optimal postoperative care, leading to improved outcomes.
