craniotomy
Pronunciation: kray-nee-OT-oh-mee
Surgical procedure involving the temporary removal of a bone flap from the skull to access the brain for treatment or diagnosis.
Full Definition
A craniotomy is a neurosurgical procedure in which a section of the skull (bone flap) is temporarily removed to provide access to the brain. Unlike a craniectomy, where the bone is permanently removed, a craniotomy involves replacing the bone flap at the procedure's conclusion. This technique is used for various indications including tumor resection, aneurysm repair, hematoma evacuation, or biopsy procedures. The size and location of the craniotomy depend on the specific pathology being addressed. Editors should distinguish this from related procedures like burr holes or craniectomy.
Usage
Usage note: Distinguish from craniectomy (permanent bone removal) and ensure anatomical location specification when applicable.
