How is brain surgery done?

Steps in Brain Surgery

1. Preoperative preparation: Before the surgery, the patient is evaluated to determine their overall health and fitness for the procedure. This may involve tests such as an MRI scan, CT scan, and blood tests. The patient is also given instructions on how to prepare for the surgery, such as fasting for 8-12 hours beforehand.

2. General anesthesia: The patient is placed under general anesthesia to ensure that they are unconscious and pain-free during the surgery.

3. Incision: The surgeon makes an incision in the scalp, usually behind the hairline. The size and location of the incision will depend on the area of the brain that needs to be accessed.

4. Craniotomy: The surgeon removes a section of the skull to create an opening to the brain. This may be done using a drill, saw, or laser.

5. Brain surgery: The surgeon uses a variety of instruments to perform the desired procedure on the brain. This may involve removing a tumor, repairing a blood vessel, or implanting a device.

6. Hemostasis: The surgeon stops any bleeding from the brain or surrounding tissue.

7. Cranioplasty: The surgeon replaces the removed section of the skull with a bone graft, metal plate, or other material to protect the brain.

8. Closure: The scalp is closed with sutures or staples.

9. Postoperative care: The patient is taken to the recovery room where their vital signs are monitored. They may also be given pain medication and antibiotics. The patient will typically stay in the hospital for several days after surgery.
