A craniotomy is a complex surgery that opens the skull to reach the brain. It’s done for many reasons, like removing tumors or fixing aneurysms. Let’s explore the craniotomy process, why it’s done, and the different types.

What is a Craniotomy? Definition and Surgical Process

A craniotomy is a surgery where part of the skull is temporarily removed to expose the brain. Johns Hopkins Medicine explains, “A craniotomy is the surgical removal of part of the bone from the skull to expose the brain.” The surgery includes several steps: preparation, incision, bone flap removal, brain surgery, and bone flap replacement.

The team plans the craniotomy’s location and size based on the patient’s condition. Advanced imaging and tools help access the brain safely and precisely.

Common Reasons for Craniotomy Procedures

Craniotomies are done for many reasons, including:

• Removing brain tumors or cysts
• Fixing aneurysms or AVMs
• Relieving pressure on the brain from trauma or swelling
• Draining abscesses or hematomas
• Treating epilepsy surgically

Each condition needs careful evaluation to decide if a craniotomy is right.

Types of Craniotomy Procedures and Their Complexity

There are many types of craniotomy procedures, each with its own complexity:

Type of Craniotomy	Description	Complexity Level
Frontal Craniotomy	Access to the frontal lobe	Moderate
Temporal Craniotomy	Access to the temporal lobe	Moderate to High
Occipital Craniotomy	Access to the occipital lobe	Moderate
Pterional Craniotomy	Access to the anterior circulation and anterior cranial fossa	High
Bifrontal Craniotomy	Access to both frontal lobes	High

The complexity of the procedure depends on the location, size of the craniotomy, and the condition being treated.
