Types of Craniectomy

A craniectomy involves removing part of the skull to access the brain. Types include:

1. Standard Craniotomy

• Removal of part of the skull, followed by replacement after surgery.

• Used for: large brain tumors, internal bleeding, skull fractures, or vascular problems.

2. Targeted / Stereotactic Craniotomy

• 3D imaging (CT or MRI) guides precise access.

• Minimizes damage to surrounding brain tissue.

• Used for small tumors or complex vascular areas.

3. Emergency Craniotomy

• Performed in critical situations, such as major brain bleeding or severe trauma.

• Goal: rapidly relieve intracranial pressure to save life.

4. Decompressive Craniotomy

• Larger portion of the skull removed to relieve pressure from swelling or large tumors.

5. Mini-Craniotomy / Keyhole Surgery

• Very small opening for precise access.

• Less invasive, less pain, and faster recovery.

• Used for small tumors or vascular issues in difficult-to-reach areas.

Indications for Craniectomy

Craniectomy is performed for conditions that threaten brain health or function, including:

1. High Intracranial Pressure (ICP)

• Persistent elevated pressure not responsive to medical treatment.

• Symptoms: severe headache, nausea, vomiting, altered consciousness, neurological problems.

2. Mass Effect on the Brain

• Detected via CT or MRI.

• Tumors, bleeding, or swelling exert pressure, threatening brain function.

3. Acute Subdural Hematoma

• Bleeding between the brain and outer covering, usually from trauma.

• Surgery relieves pressure.

4. Acute Epidural Hematoma

• Bleeding between the skull and outer brain layer.

• Often requires urgent intervention.

5. Severe Brain Swelling (Edema)

• Caused by trauma, large tumors, or severe infections.

• Skull removal allows brain expansion without additional pressure.

6. Failure of Medical Management

• When medications or other treatments cannot reduce intracranial pressure.

7. Traumatic Brain Injuries (TBI)

• Severe head injuries causing swelling or bleeding.

• Surgery relieves pressure and protects brain function.

8. Hemorrhagic Stroke

• Surgery manages swelling and prevents complications.

9. Brain Tumors

• Tumors increase localized pressure.

• Surgery removes the tumor and relieves pressure.

10. Severe Brain Infections

• Such as abscesses or encephalitis causing major swelling.
