What to Burr Hole

A burr hole is a small opening made in the skull to access the brain. There are multiple reasons for making burr holes, which include:

* To relieve pressure on the brain. Burr holes can be made in cases of increased intracranial pressure (ICP), which can occur from a variety of causes, such as head injury, stroke, or brain tumor. Relieving pressure can help to prevent brain damage and improve outcomes.

* To drain fluid from the brain. Burr holes can be made to drain cerebrospinal fluid (CSF), which is the clear fluid that bathes the brain and spinal cord. CSF drainage can help to reduce ICP and improve brain function.

* To access the brain for surgery. Burr holes can be used to introduce surgical instruments into the brain for a variety of procedures, such as brain tumor removal, aneurysm repair, and deep brain stimulation.

* To insert a ventriculoperitoneal (VP) shunt. A VP shunt is a device that is used to drain CSF from the brain to the abdomen. Burr holes are made to insert the shunt into the brain and to tunnel the shunt under the skin to the abdomen.

The procedure of making a burr hole is called burr hole surgery. Burr hole surgery is a relatively simple procedure that can be performed in a hospital or outpatient setting. The procedure takes about 30-45 minutes and is usually done under general anesthesia. During burr hole surgery, the surgeon will make a small incision in the scalp and then use a drill to make a hole in the skull. The surgeon will then insert a drainage tube or surgical instruments through the burr hole. After the procedure is complete, the incision will be closed with sutures or staples.

Burr hole surgery is a safe and effective procedure. However, there are some potential risks associated with the procedure, such as bleeding, infection, and brain injury. The surgeon will discuss these risks with you before the procedure.
