Some issues Dr. Fredric B. Meyer, MD can help you with:

Craniotomy

Craniotomy and craniectomy are surgical procedures used to access the brain and treat tumors, intracranial pressure, or other conditions. These surgeries are performed by creating holes in the skull, or cranium, to expose the brain. The opening in the skull can be immediately replaced (craniotomy), or it can be replaced during a later procedure (craniectomy). The following procedures use craniotomy or craniectomy:

Brain biopsy, which is done by guiding a needle through the opening in the skull to the targeted area of the brain. This procedure may be performed through an open or minimally invasive approach. The minimally invasive approach, called stereotactic brain biopsy, uses a computer to guide the needle.
Brain tumor resection, which may be performed following a biopsy with image guidance. Depending on the size and location of the tumor, resection will require 2-5 hours.
Cerebrospinal fluid (CSF) leak repair, particularly for leaks that continue for a long period of time after a surgery. CSF leaks that are left untreated can lead to complications such as meningitis, an inflammation of the outer layers (meninges) of the brain.
Decompression, often following a stroke or injury. Decompressive craniotomy or craniectomy temporarily removes a flap from the skull to give the brain more room for swelling, which provides pressure relief.
Hematoma evacuation, which can also relieve pressure on the brain. A hematoma is a swelling of clotted blood. It can occur between the skull and the outer covering of the brain, or dura (epidural), between the dura and the brain (subdural), and within the brain (intracerebral). Craniotomy or craniectomy may be used to access and remove the hematoma.

To perform a craniotomy, the surgeon will need to make an incision on the scalp to expose the skull. Some of the hair may be shaved, and the scalp will be cleaned with antiseptic solution. Following the incision, the surgeon will use a drill to remove a piece of the skull, called a bone or skull flap. If the surgeon needs to reach a tumor or perform an aspiration, the dura, which covers the brain, will be incised (cut) to access the lesion. The bone flap will be reattached once the surgeon has completed the procedure. If the surgeon is performing a craniectomy, the same steps will be followed, but a mesh piece will be placed where the bone flap was, and the scalp will be surgically closed. Patients will need to wear a special helmet for a few months after the procedure. The bone flap will be preserved and replaced during a later operation, or it may never be replaced.

Patient recovery period can range from two days to two weeks, depending on the specific procedure and condition. Patient will require monitoring and may be given medication for pain or brain swelling. Patients will have to restrict their physical activity for some time after the procedure, and they may need to work with a physical therapist.

Hydrocephalus

Normally, the brain is bathed in a liquid called cerebrospinal fluid. This fluid cushions and nurtures the brain cells as it flows around and through the brain. Sometimes, cerebrospinal fluid does not get reabsorbed into the body properly, or a blockage in the brain can stop it from flowing. This causes a buildup of pressure called hydrocephalus. This condition affects a wide range of people, but it is much more prevalent among infants and older adults. Left untreated, hydrocephalus can cause uncomfortable symptoms, such as headaches and blurred vision, and eventually may cause brain damage.

Hydrocephalus is most often treated with an implanted device called a shunt. A shunt is a long, thin tube that is used to drain excess fluid. One end is placed within the brain. The tube runs under the skin, along the neck behind the ear, and to another part of the body where the fluid can be reabsorbed. Most often this is the abdomen, but the chest or other areas can also be used. Shunts have a valve that allows doctors to monitor and control the pressure within the brain. Insertion of a shunt is a surgical procedure that takes one to two hours. Incisions are made in the head and the abdomen, and the shunt is threaded into place before the openings are stitched closed.

In cases where hydrocephalus is caused by a blockage, a procedure called endoscopic third ventriculostomy, or ETV, may be performed. During this procedure, a surgeon makes a dime-sized hole in the skull and uses a thin tube with a camera on the end (called an endoscope) to see inside the brain. The surgeon punctures a hole in the floor of the third ventricle, a fluid-filled space within the brain. The hole provides an opening for cerebrospinal fluid to flow around the blockage, normalizing pressure. The entire procedure usually takes less than an hour and patients can often go home the following day. ETV can provide a permanent and safe alternative to a shunt, but it is only useful for patients whose hydrocephalus is caused by a blockage.
