Craniotomy

A craniotomy is a surgical procedure that involves removing a portion of the skull to expose the brain. Surgeons utilize specialized tools to extract a segment of bone known as a “bone flap,” which is temporarily removed and later replaced once the brain surgery is finished.

Craniotomy procedures typically consist of the following steps:

1. Incision:
   A scalp incision is made to access the skull bone.
2. Bone Flap Removal:
   A section of the skull bone (bone flap) is carefully extracted using specialized instruments to gain access to the brain.
3. Brain Exposure and Surgery:
   The neurosurgeon opens the protective layer covering the brain (the dura) and performs the required surgical procedure, which may involve tumor removal, vascular repairs, or other interventions.
4. Closure:
   After the surgery is completed, the bone flap is repositioned and secured with plates, and the scalp incision is closed with sutures or staples.

These steps are designed to provide safe access to the brain while minimizing tissue damage and facilitating recovery.
