Brain Surgery Types

There are different types of Brain Surgery. The type of surgery that is implemented depends on the problem being treated.


In this kind of surgery, a hole is made inside the skull near the affected area, this hole is known as the brain flap. This kind of surgery is also known as open brain surgery and is done to treat the following problems.

  • Remove Tumors
  • Clip off an aneurysm
  • Blood or fluid draining from infection
  • Remove abnormal brain tissue

Once the surgery is over the hole or the bone flap is replaced with plates, wires or sutures. The bone flap is generally kept open to treat any swelling or tumor that may arise in the brain. The procedure of keeping the bone flap open is known as a craniectomy.


In this procedure a small amount of brain tissue or a tumor is removed so it can be further examined under a microscope. This procedure (Biopsy) involves a small incision and hole in the skull.

Deep Brain Stimulation:

This kind of surgery is done in the case of Parkinson’s disease where a battery-operated medical device is implanted inside the brain to generate stimulation. This medical device is implanted at some specific areas of the brain where the pulse generator can send stimulation.


 This is a process in which a thin threadlike tube is inserted inside the brain to remove brain tissue. This tube has a light and camera on the end, and the surgery is performed by monitoring on the screen. 

Posterior fossa decompression:

This kind of operation is to remove a small portion of bone from the bottom of the skull so that the pressure is relieved from the spinal cord. This surgery takes place at the cerebellum and the brainstem.

Thrombectomy and cerebral aneurysm repair: 

This type of brain surgery is performed when there is a clot in the brain artery or rupture in the brain that causes bleeding. The surgical instrument is inserted from the groin and reaches the brain vessels using contrast dye. This contrast identifies the place where there is clot to remove the same.

Brain surgery risks:

A lot of risks are involved with brain surgery , some are problems of speech, memory loss, muscle weakness, issues in vision, coordination problems. Other risks are 

  • Blood clot
