Burr Hole Drainage

This procedure creates one or more holes in the skull to release excess fluid pressure in the brain caused by chronic subdural hematoma.

The surgeon makes a tiny incision in the scalp and drills one or two holes through the skull, exposing the dura.  The dura is then opened to allow the fluid to drain from the inside of the skull, reducing the pressure.  Saline may be injected to help wash out the fluid.  The wound is then closed with sutures or surgical staples.
