Brain surgery is an operation to treat problems in the brain and surrounding structures.


Before surgery, the hair on part of the scalp is shaved and the area is cleaned. The doctor makes a surgical cut through the scalp. The location of this cut depends on where the problem in the brain is located.

The surgeon creates a hole in the skull and removes a bone flap.

If possible, the surgeon will make a smaller hole and insert a tube with a light and camera on the end. This is called an endoscope. The surgery will be done with tools placed through the endoscope. MRI or CT scan can help guide the doctor to the proper place in the brain.

During surgery, your surgeon may:

Clip off an aneurysm to prevent bleeding

Remove a tumor or a piece of tumor for a biopsy

Remove abnormal brain tissue

Drain blood or an infection

Free a nerve

Take a sample of brain tissue to help diagnose nervous system diseases

The bone flap is usually replaced after surgery, using small metal plates, sutures, or wires. This brain surgery is called a craniotomy.

The bone flap may not be put back if your surgery involved a tumor or an infection, or if the brain was swollen. This brain surgery is called a craniectomy. The bone flap may be put back during a future operation.

The time it takes for the surgery depends on the problem being treated.

Why the Procedure is Performed

Brain surgery may be done if you have:

Brain tumor

Bleeding (hemorrhage) in the brain

Blood clots (hematomas) in the brain

Weaknesses in blood vessels (brain aneurysm repair)

Abnormal blood vessels in the brain (arteriovenous malformations; AVM)

Damage to tissues covering the brain (dura)

Infections in the brain (brain abscesses)

Severe nerve or face pain (such as trigeminal neuralgia, or tic douloureux)

Skull fracture

Pressure in the brain after an injury or stroke


Certain brain diseases (such as Parkinson disease) that may be helped with an implanted electronic device

Hydrocephalus (brain swelling)


Risks for anesthesia and surgery in general are:

Reactions to medicines

Problems breathing

Bleeding, blood clots, infection

Possible risks of brain surgery are:

Problems with speech, memory, muscle weakness, balance, vision, coordination, and other functions. These problems may last a short while or they may not go away.

Blood clot or bleeding in the brain.




Infection in the brain, wound, or skull.

Brain swelling.

Before the Procedure

Your doctor will examine you, and may order laboratory and imaging tests.

Tell your doctor or nurse:

If you could be pregnant

What drugs you are taking, even drugs, supplements, vitamins, or herbs you bought without a prescription

If you have been drinking a lot of alcohol

If you take aspirin or anti-inflammatory drugs such as ibuprofen

If you have allergies or reactions to medicines or iodine

During the days before the surgery:

You may be asked to temporarily stop taking aspirin, ibuprofen, warfarin (Coumadin), and any other blood thinning medicines.

Ask your doctor which drugs you should still take on the day of the surgery.

Try to stop smoking. Smoking can slow healing after your operation. Ask your doctor for help.

Your doctor or nurse may ask you to wash your hair with a special shampoo the night before surgery.

On the day of the surgery

You will likely be asked not to drink or eat anything for 8 to 12 hours before the surgery.

Take the drugs your doctor told you to take with a small sip of water.

Arrive at the hospital on time.

After the Procedure

After surgery, you will be closely monitored by your health care team to make sure your brain is working properly. The doctor or nurse may ask you questions, shine a light in your eyes, and ask you to do simple tasks. You may need oxygen for a few days.

The head of your bed will be kept raised to help reduce swelling of your face or head. The swelling is normal after surgery.

Medicines will be given to relieve pain.

You will usually stay in the hospital for 3 to 7 days. You may need physical therapy (rehabilitation).

After you go home, follow any self-care instructions you're given.

Outlook (Prognosis)

How well you do after brain surgery depends on the condition being treated, your general health, which part of the brain is involved, and the specific type of surgery.
