The term “brain surgery” refers to various medical procedures that involve repairing structural problems in the brain.
There are numerous types of brain surgery. The type used is based on the area of the brain and condition being treated. Advances in medical technology have enabled surgeons to operate on portions of the brain without a single incision near the head.
Brain surgery is a critical and complicated process. The type of brain surgery done depends highly on the condition being treated. For example, a brain aneurysm is typically repaired using an endoscope. If it has ruptured, a craniotomy may be used. Surgeons, to be as careful and thorough as possible, treat each surgery on a case-by-case basis.
Brain surgery is done to correct physical abnormalities in the brain. This can be due to birth defect, disease, injury, or other problems.
You may need brain surgery if you have any of the following conditions in or around the brain:
- abnormal blood vessels
- an aneurysm
- blood clots
- damage to the protective tissue called the “dura”
- nerve damage
- Parkinson’s disease
- pressure after injury
- skull fracture
- a stroke
Not all of these conditions require brain surgery, but many may be helped by it, especially if they pose a risk for worse health problems. For example, a brain aneurysm doesn’t require open brain surgery, but you may need open surgery if the vessel ruptures.
There are several different types of brain surgery. The type used depends on the problem being treated.
A craniotomy involves an incision into the scalp and creating a hole in the skull, known as a bone flap. The hole and incision are made near the area of the brain being treated.
During open brain surgery, your surgeon may opt to:
- remove tumors
- clip off an aneurysm
- drain blood or fluid from an infection
- remove abnormal brain tissue
When the procedure is complete, the bone flap is usually secured in place with plates, sutures, or wires. The hole may be left open in the case of tumors, infection, or brain swelling. When left open, the procedure is known as a craniectomy.
This procedure is used to remove a small amount of brain tissue or a tumor so it can be examined under a microscope. This involves a small incision and hole in the skull.
Minimally Invasive Endonasal Endoscopic Surgery
This type of surgery allows your surgeon to remove tumors or lesions through your nose and sinuses. It allows them to access parts of your brain without making an incision. The procedure involves the use of an endoscope, which is a telescopic device equipped with lights and a camera so the surgeon can see where they’re working. Your doctor can use this for tumors on the pituitary gland, tumors on the base of the skull, and tumors spreading across the brain.
Minimally Invasive Neuroendoscopy
Similar to minimally invasive endonasal endoscopic surgery, neuroendoscopy uses endoscopes to remove brain tumors. Your surgeon may make small, dime-sized holes in the skull to access parts of your brain during this surgery.
Find a Doctor
All surgical procedures carry some risk. Brain surgery is a major medical event. It carries extra risk.
Possible risks associated with brain surgery include:
- allergic reaction to anesthesia
- bleeding in the brain
- a blood clot
- brain swelling
- a coma
- impaired speech, vision, coordination, or balance
- infection both in the brain or at the wound site
- memory problems
Your doctor will give you complete instructions on how to prepare for the procedure.
Tell your doctor about any medications you’re taking, including over-the-counter medicine and nutritional supplements. You most likely will have to stop taking these medications days before the procedure. Tell your doctor about any prior surgeries, allergies, or if you’ve been drinking a lot of alcohol.
You may be given a special soap to wash your hair with before surgery. Also, be sure to pack whatever belongings you may need while you stay at the hospital.
Immediately after the surgery, you’ll be closely monitored to ensure everything is working properly. You’ll be seated in a raised position to prevent swelling in your face and brain.
Recovery from brain surgery depends on the type of procedure done. A typical hospital stay for brain surgery can last up to a week or more. The length of your hospital stay will depend on how well your body responds to the surgery. You’ll be on pain medications during this time.
Before you leave the hospital, your doctor will explain the next steps of the process. This will include how to care for the wound if you have one.
