craniotomy
Pronunciation: kray-nee-OT-oh-mee
A surgical procedure involving the temporary removal of part of the skull to access the brain.
Full Definition
A craniotomy is a neurosurgical procedure where a section of the skull (bone flap) is surgically removed to provide access to the brain for various therapeutic interventions. The procedure may be performed to remove tumors, repair aneurysms, drain blood clots, or treat other brain conditions. After the surgical intervention is completed, the bone flap is typically replaced and secured with plates, screws, or wires. This differs from a craniectomy, where the bone flap is not immediately replaced. The procedure requires careful planning using neuroimaging to minimize damage to healthy brain tissue.
Usage
Usage note: Distinguish from craniectomy, where the bone flap is not replaced.
