About General Brain Surgery
A neurosurgeon performs brain surgery. Brain surgery is done to correct physical abnormalities in the brain. These can be due to birth defects, disease, injury, or other problems.
What is brain surgery?
Brain surgery is a broad term that refers to various medical procedures aimed at repairing structural problems within the brain. These procedures are critical and complex, and the type of brain surgery performed depends highly on the condition being treated.
Brain surgery is performed to correct physical abnormalities in the brain, which can be due to birth defects, disease, injury, or other problems. Conditions that may require brain surgery include abnormal blood vessels, aneurysms, bleeding, blood clots, epilepsy, abscesses, nerve damage or irritation, Parkinson's disease, pressure after head injury, skull fractures, strokes, brain tumors, and fluid buildup in the brain. There are several types of brain surgery:
A craniotomy involves making an incision in the scalp and creating a hole known as a bone flap in the skull. The hole and incision are made near the area of the brain being treated. During open brain surgery, the surgeon may remove tumors, clip off an aneurysm, drain blood or fluid from an infection, or remove abnormal brain tissue.
A biopsy is a procedure 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 allows the surgeon to remove tumors or lesions through your nose and sinuses. It allows them to access parts of your brain without making an incision.
Deep brain stimulation involves inserting electrodes along the brain to stimulate specific regions. A person will also have a pulse generator on their chest.
Advances in medical technology have enabled surgeons to operate on portions of the brain without a single incision in or near the head. However, not all conditions require brain surgery, but many may be helped by it, especially if they pose a risk for more serious health problems.
Who performs brain surgery?
A brain surgery is performed by a neurosurgeon, a medical specialist who has received extensive training in the diagnosis and surgical treatment of disorders of the central and peripheral nervous system. This includes conditions affecting the brain, spinal cord, peripheral nerves, and the structures supporting these areas.
Neurosurgeons undergo rigorous education and training, including four years of undergraduate studies, four years of medical school, and a residency program that lasts for six to seven years. Some neurosurgeons may also complete additional fellowship training in a specific area of neurosurgery. This complex field requires a high level of expertise and precision, reflecting the critical role of the brain in controlling all body functions.
During a brain surgery, the neurosurgeon is supported by a team of highly trained medical professionals. This team typically includes anesthesiologists, who ensure the patient is safely anesthetized during the procedure; nurses, who assist with the surgery and patient care; and sometimes other specialists, such as oncologists, radiation oncologists, and vascular surgeons, depending on the nature of the condition being treated.
Neurosurgeons use a variety of advanced techniques and technologies to perform brain surgery, including microsurgery, endoscopy, stereotactic radiosurgery, and deep brain stimulation. The choice of technique depends on the specific condition of the patient and the location and nature of the problem within the brain. General brain surgery is used for these conditions in or around the brain:
Abnormal blood vessels
An aneurysm
Bleeding
Blood clots
Damage to the protective tissue called the “dura”
Epilepsy
Abscesses
Nerve damage or nerve irritation
Parkinson’s disease
Pressure after head injury
Skull fracture
A Stroke
Brain tumors
Fluid building up in the brain
Although not all of these conditions require brain surgery, the operation may help them. Especially if these conditions pose a risk for more serious health problems.
What are some types of brain surgery?
Craniotomy: Removing a piece of skull to gain access to the brain for removing a brain tumor, abnormal tissue, blood, or blood clot.
Biopsy: Performed when imaging has detected a potential abnormality.
Deep brain stimulation (DBS): An implantable pulse generator implanted to deliver electrical stimulation to specific areas in the brain.
Neuroendoscopy: A minimally invasive technique using an endoscope to access or remove brain tissue.
Posterior fossa decompression: This treatment involves parts of the brain called the cerebellum and brainstem.
Thrombectomy and cerebral aneurysm repair: Using a catheter or thin metal wires through a large blood vessel through a patient’s groin to reach the brain vessels, and by using contrast dye to identify the problematic blood vessel without opening up the skull.
Types of Brain Tumor Surgery
Brain tumor surgery is a critical procedure performed to remove tumors in the brain. There are several types of brain tumor surgeries, each designed to address different types of tumors and their locations within the brain.
Craniotomy: This is the most common type of brain tumor surgery. In a craniotomy, a portion of the skull is removed to access the tumor. The surgeon then removes as much of the tumor as possible. After the procedure, the piece of the skull is replaced.
Biopsy: A biopsy involves removing a small piece of the tumor for examination under a microscope. This can be done through a needle biopsy, where a long, thin needle is inserted through a small hole in the skull, or as part of a craniotomy.
Endoscopic Brain Surgery: This minimally invasive procedure uses a small tube called an endoscope. The endoscope is inserted through a small hole in the skull or through the nose to reach the tumor. The surgeon can then remove the tumor or take a biopsy.
Transsphenoidal Surgery: This procedure is used for tumors in the pituitary gland or in the bottom part of the brain. The surgeon reaches the tumor through the nose and sinuses without making an incision in the skull.
Neuroendoscopy: This is a minimally invasive procedure where a small hole is made in the skull, and a small camera is inserted to view the tumor and surrounding brain tissue. Special instruments are then used to remove the tumor.
Stereotactic Radiosurgery: Despite its name, this isn't a traditional surgery. Instead, it uses focused radiation to treat the tumor.
Laser Interstitial Thermal Therapy (LITT): This is a minimally invasive procedure that uses a laser to heat and destroy the tumor. It's often used for hard-to-reach tumors or tumors that can't be removed with traditional surgery.
Each of these procedures has its risks and benefits, and the choice of procedure depends on the type, size, and location of the tumor, as well as the patient's overall health. Patients need to discuss these factors thoroughly with their healthcare provider to ensure they are making the best possible decision for their health.
Brain Surgery Side Effects
Problems with speech
Memory struggles
Muscle weakness
Balance issue
Vision loss
Coordination problem
Brain Surgery Recovery
Patients will feel tired for several weeks after brain surgery, as well as headaches or problems concentrating. It can take 4 to 8 weeks to recover from surgery.
