What is a Craniotomy?
Removal of part of skull allowing surgeon to operate on brain and/or remove tumors, blood clots, etc.
A craniotomy is a surgical procedure that involves removal of a portion of the skull to access the tissues of the brain. This surgery is performed by a neurosurgeon while the patient is under anesthesia. We can perform a craniotomy on any part of the skull, depending on the location of the brain that needs to be accessed. The portion of the skull that is temporarily opened to provide access to the brain is called a bone flap. When the bone flap is removed from the lower back part of the skull, called the suboccipital region, the surgery is known as a suboccipital craniotomy.
Who needs a craniotomy?
A craniotomy may be needed by patients suffering from a variety of conditions within their skull including:
- Arteriovenous malformations: Arteriovenous malformations, or AVMs, are a tangle of blood vessels that disrupt the normal flow of blood and may spontaneously bleed. A craniotomy is required if an AVM needs to be removed surgically.
- Aneurysms: An aneurysm is a weak area in a blood vessel that causes bulging or ballooning of that vessel. A craniotomy is required if an aneurysm needs to be clipped.
- Abscesses: A craniotomy will be needed for the removal or drainage of an abscess.
- Blood clots or Pressure: A craniotomy is required for the removal of blood clots in the brain, like those that form after a traumatic brain injury.
- Tumors: A craniotomy would be performed on individuals with brain tumors that required a biopsy or removal.
What happens after a Craniotomy is performed?
After surgery, we move the patient to an intensive care unit, or ICU, for close monitoring of their vital signs and their exam.
The patient will be periodically examined and appropriate tests and exams performed.
The patient will remain in the hospital for a period time. The duration of the postoperative stay can vary from a few days to a few weeks, depending on the reason for the craniotomy.
