Types of Brain Surgery Methods!
1. Craniotomy brain surgery
A craniotomy is one of the most common types of brain surgery. This procedure involves removing a portion of the skull to access the brain. The bone flap is typically replaced at the end of the surgery. Craniotomies variety of purposes, including:
Tumor Removal: To excise brain tumors.
Aneurysm Clipping: Treat aneurysms by placing a clip at the base to prevent bleeding.
Traumatic Brain Injury: To relieve pressure from swelling or bleeding.
Epilepsy Surgery: To remove the part of the brain causing seizures.
Procedure: The patient is usually under general anesthesia. The surgeon makes an incision in the scalp, drills a hole in the skull, and uses a specialized saw to create the bone flap. After addressing the issue, the bone flap is securing back into the place.
2. Endonasal Endoscopic Surgery
Endonasal endoscopic surgery is a minimally invasive technique using to access the brain through the nasal passages. It is often employed to remove tumors and lesions located at the base of the skull or in the pituitary gland.
Procedure: An endoscope, a thin tube with a camera and light, is inserted through the nostrils. This allows the surgeon to navigate and operate without making a large incision. Specialized instruments are used to remove the tumor or lesion
3. Stereotactic Surgery
Stereotactic surgery uses three-dimensional imaging to precisely target specific areas of the brain. This method is particularly useful for biopsies, deep brain stimulation (DBS), and radiosurgery.
Biopsy: To obtain a tissue sample for diagnostic purposes.
Deep Brain Stimulation: For treating movement disorders such as Parkinson’s disease and essential tremor.
Radiosurgery: To deliver focused radiation to treat tumors, arteriovenous malformations (AVMs), and other abnormalities.
Procedure: The patient’s head is stabilized in a frame, and imaging techniques such as MRI or CT scans are used to map the brain. A small hole is drilled into the skull to insert instruments or electrodes with pinpoint accuracy.
4. Awake Brain Surgery
Awake brain surgery, or awake craniotomy, is performed while the patient is conscious. This approach is particularly beneficial for surgeries involving areas of the brain that control speech, movement, and other critical functions.
Procedure: The patient receives local anesthesia and sedation. Once the skull is opening, the sedation is reducing to allow the patient to respond to stimuli and tasks. This helps the surgeon ensure that essential brain functions are preserved during the procedure
5. Transsphenoidal brain Surgery
Transsphenoidal surgery is another minimally invasive method using to remove pituitary tumors. The approach is through the sphenoid sinus, located behind the nasal passages.
Procedure: An endoscope is inserting through the nose and sphenoid sinus to access the tumor. This method avoids the need for a craniotomy, reducing recovery time and complications.
6. Laser Ablation
Laser ablation, also known as laser interstitial thermal therapy (LITT), is a minimally invasive technique using to treat brain tumors and epileptic foci. It uses laser energy to destroy abnormal tissue.
Procedure: A small incision is made in the scalp, and a laser probe is inserting through a hole drilling in the skull. MRI guidance is to target and heat the abnormal tissue, causing it to disintegrate.
7. Shunt brainSurgery
Shunt surgery is commonly performing to treat hydrocephalus, a condition characterizing by an accumulation of cerebrospinal fluid (CSF) in the brain.
Procedure: A flexible tube, or shunt, is placed in the brain to divert excess CSF to another part of the body, such as the abdominal cavity, where it can be absorbed.
8. Endoscopic Third Ventriculostomy (ETV)
ETV is an alternative treatment for hydrocephalus that avoids the need for a shunt. It creates a new pathway for CSF to flow within the brain.
Procedure: An endoscope is using to create an opening in the floor of the third ventricle, allowing CSF to bypass the obstruction and be absorbed.
9. Neuroendoscopy
Neuroendoscopy is a minimally invasive procedure using for diagnostic and therapeutic purposes, including tumor removal, cyst drainage, and biopsy.
Procedure: An endoscope is inserting through a small incision or natural opening to access the brain. It provides visual guidance and allows the surgeon to perform delicate operations with minimal disruption to surrounding tissues.
10. Burr Hole Surgery
Burr hole surgery involves drilling one or more small holes in the skull to access the brain. It is commonly using for procedures such as:
Subdural Hematoma Evacuation: To remove blood clots.
Ventriculostomy: To drain excess CSF.
Procedure: The surgeon drills a hole in the skull, inserts a catheter or other instruments to address the issue, and then closes the hole.
11. Functional Neurosurgery
Functional neurosurgery focuses on altering or modulating neural activity to treat neurological and psychiatric disorders.
Deep Brain Stimulation (DBS): Electrodes are implanting in specific brain regions to regulate abnormal electrical signals.
Vagus Nerve Stimulation (VNS): A device is implanting to stimulate the vagus nerve, using for epilepsy and depression treatment.
12. Gamma Knife Surgery
Gamma knife surgery is a form of radiosurgery that uses focused gamma rays to treat small to medium-sized brain tumors, AVMs, and other brain disorders.
Procedure: The patient’s head is securing in a frame, and imaging include to direct gamma rays precisely to the target area, minimizing damage to surrounding tissues.
13. Microsurgery
Microsurgery involves the use of a microscope to perform intricate operations on small structures within the brain. include:
Aneurysm Repair: To place clips or coils.
Tumor Removal: For precise excision of small tumors.
Procedure: The surgeon uses a high-powered microscope to view the surgical area and specialized instruments to operate with great precision.
14. Spinal Surgery
Although not directly related to the brain, spinal surgery is a critical part of neurosurgery, addressing issues such as spinal cord tumors, herniated discs, and spinal stenosis.
Procedure: Depending on the condition, various techniques such as laminectomy, discectomy, or spinal fusion may be employing to relieve pressure, remove tumors, or stabilize the spine.
