Craniotomy Procedure

A craniotomy is a surgical procedure that involves temporarily removing a portion of the skull, known as a bone flap, to access the brain. This allows neurosurgeons to perform various operations, such as removing tumors, clipping aneurysms, or relieving pressure on the brain.

Types of Craniotomy

• Frontal craniotomy: involves removing a portion of the frontal bone to access the frontal lobe of the brain.
• Parietal craniotomy: involves removing a portion of the parietal bone to access the parietal lobe of the brain.
• Temporal craniotomy: involves removing a portion of the temporal bone to access the temporal lobe of the brain.
• Occipital craniotomy: involves removing a portion of the occipital bone to access the occipital lobe of the brain.

Indications for Craniotomy

Craniotomy is typically performed to:

• Treat brain tumors, such as gliomas or meningiomas.
• Clip or repair aneurysms or arteriovenous malformations (AVMs).
• Relieve pressure on the brain due to trauma, hemorrhage, or other conditions.
• Remove blood clots or abscesses from the brain.
• Implant devices, such as shunts or stimulators, to treat conditions like hydrocephalus or Parkinson's disease.

Surgical Technique

The craniotomy procedure typically involves the following steps:

1. The patient is administered general anesthesia and positioned on the operating table.
2. The surgeon makes an incision in the scalp and reflects the skin and muscle to expose the skull.
3. A specialized saw or drill is used to remove a portion of the skull, creating a bone flap.
4. The bone flap is carefully removed and set aside, allowing access to the brain.
5. The surgeon performs the necessary operation, such as tumor removal or aneurysm clipping.
6. Once the procedure is complete, the bone flap is replaced and secured with plates, screws, or sutures.
7. The scalp incision is closed, and the patient is taken to the recovery room for post-operative care.

Risks and Complications

As with any surgical procedure, craniotomy carries risks and potential complications, including:

• Infection or meningitis.
• Bleeding or hematoma formation.
• Swelling or edema of the brain.
• Damage to surrounding brain tissue or nerves.
• Seizures or epilepsy.
• Cognitive or behavioral changes.

Recovery and Follow-up

After a craniotomy, patients typically require:

• Intensive care unit (ICU) monitoring for several days.
• Pain management with medication.
• Antibiotics to prevent infection.
• Follow-up appointments with the neurosurgeon to monitor healing and remove sutures or staples.
• Rehabilitation therapy, such as physical, occupational, or speech therapy, to regain strength and function.
