Of the many subspecialties in neurosurgery, brain surgery is often regarded as the most technically challenging. Over the course of his career, Dr. Banister has honed his skills in brain surgery, establishing a reputation of being a surgeon who provides consistently excellent care. An important part of his practice is making sure that each patient truly understands not only their diagnosis, but their options.

It is Dr. Banister’s steadfast belief that well-informed patients make better decisions together with their doctor. This collaborative approach to treatment, combined with Dr. Banister’s superior surgical expertise, truly sets him apart from other brain surgeons in the region.


Brain Tumor

A brain tumor is a cluster of tissue that grows abnormally in an area where it shouldn’t be, disrupting normal brain function. Depending on the tissue that makes up the tumor, the tumor may be benign (i.e., noncancerous) or malignant (i.e., cancerous). Indications for treatment may vary based on the tumor’s type and location, but most tumors need to be removed. Dr. Banister has years of experience performing tumor excision procedures. If radiation or chemotherapy are better treatment options for your tumor type, Dr. Banister can refer you to a respected and trustworthy neuro-oncologist in the area.


A migraine is a severe recurring headache that usually affects one side of the head. It is often accompanied by a throbbing sensation, nausea, sensitivity to light, and disturbed vision. Some migraines are caused by compression of the peripheral sensory nerves that surround the face, causing migraines so severe that they interfere with everyday activities. When these nerves are compressed, they may increase the frequency and severity of a migraine, so relieving pressure on the nerves may reduce the incidence and duration of future migraines. In such cases, Dr. Banister may recommend surgical decompression of the peripheral sensory nerves.

Subdural Hematoma

A subdural hematoma is a type of closed head injury that occurs when a pool of blood forms between the brain and its outermost covering (called the dura). There is only so much room inside your skull, so when blood starts to occupy space, it compresses brain tissue, causing brain injury or death. Subdural hematomas can also arise more gradually, resulting from a slow bleed in the brain. A subdural hematoma is a medical emergency treated either by drilling small holes called bur holes into the skull to drain the bleed, or by removing a larger piece of the skull in a procedure known as a craniotomy to remove a solid blood clot.

Surgical Procedures: Brain

Brain Tumor Surgery

Provided that they are not in a difficult-to-access or overly sensitive part of the brain, most brain tumors need to be removed surgically. Most benign tumors can be removed surgically without the need for additional radiation therapy. However, if a tumor is malignant, adjuvant radiation therapy may be warranted to ensure that all cancerous cells are killed. The location and type of tumor will determine the surgical approach and the procedure type. No matter the type of procedure, patients are heavily sedated and will not feel any pain during the procedure.

Surgery for Subdural Hematoma

An acute subdural hematoma (that is, subdural hematoma that occurs quickly, usually after injury) is a medical emergency that must be addressed as early as possible to relieve pressure on the brain, which can cause brain damage. In cases of acute subdural hematoma, a portion of the skull centered over the thickest area of the hematoma is removed. This is done to allow the brain space to swell and to stop the bleeding. After surgical treatment for subdural hematoma, patients are often kept for observation to make sure the pressure in their skull remains at a safe level.

Surgical decompression of the peripheral sensory nerves

In an effort to decrease the frequency, intensity and duration of severe migraines, surgical decompression of the peripheral sensory nerves may be recommended. This outpatient procedure involves usually only takes several hours, and the skull itself is not interrupted. Instead, this is a minimally invasive procedure that is only performed if the compressed nerve can be identified with a high degree of certainty. This procedure is associated with a relatively brief recovery period.
