What is a craniotomy?
100
Forty percent of primary brain tumors, the majority are malignant.
What is a glioma?
200
It is used to diagnose tumors, abscesses, ligament damage, and disc herniation.
What is MRI (magnetic resonance imaging)?
200
It is used prior to surgery to assess blood flow, and intraoperatively for real time imagining of cysts, tumors, and other structures.
What is ultrasonography?
200
It is a horse shoe shaped and used for cervical spine surgery.
What is a Mayfield Headrest?
200
Access to the cranium is achieved by creating this (a removable section of the cranium)
What is a bone flap?
200
This is the most common tumor in children.
What is a medulloblastoma?
300
It combines standard MRI technology with a head frame or magnetic markers called fiducials to pinpoint a particular location in the brain.
What is Steriotactic MRI?

What is Digital Subtraction Angiography (DSA)?
500
It measures sensory impulses from the body to the brain. It may be done preoperatively to assess nerve damage, or intraoperatively to monitor changes in the nerves during surgery.
What is Somatosensory Evoked Potentials (SSEP)?
500
It delivers diffuse energy for better coagulation of bleeding vessels around the target tissue.
What is the Nd:YAG laser?
500
It is done to correct premature closure of an infant's suture line (craniosynostosis) by separating the bones and treating them to prevent resealing.
