A craniotomy is a surgical operation where part of the skull bone, called the bone flap, is temporarily removed to allow access to the brain. There are different types of craniotomies depending on the size and location of bone removed. After exposing the brain, the operation becomes more specific for the problems being treated. Craniotomies are performed for a variety of reason including:

  • Treating brain tumors
  • Repairing an aneurysm
  • Removing blood clots
  • Removing an arteriovenous malformation (AVM)
  • Repairing skull fractures
  • Treating epilepsy
  • Implanting stimulators for movement disorders like Parkinson’s disease
