Craniectomy vs Craniotomy

A craniectomy is a surgical procedure where a part of the skull is removed and not immediately replaced. It is usually done to relieve pressure in the brain after trauma, stroke, or swelling.

A craniotomy, on the other hand, is when a part of the skull is temporarily removed and then replaced after surgery. This allows surgeons to access the brain for tumor removal, aneurysm repair, or other procedures.

Examples:

A patient with severe brain swelling after an accident may undergo a craniectomy to prevent damage.
A surgeon performing a tumor removal will typically do a craniotomy and replace the skull afterward.
During emergency treatment of an aneurysm, a craniotomy allows the surgeon to operate and then restore the skull.

The Origin of Craniectomy vs Craniotomy

Both words come from Greek roots:

Craniectomy: “cranio” means skull, and “ectomy” means removal.
Craniotomy: “cranio” means skull, and “tomy” means cutting or making an opening.
