Overview:
A craniotomy is an operation on the skull to access the brain. A small area of your child’s head will be shaved, with a cut made on their scalp, a skin flap peeled back, and a piece of bone cut out to access their brain underneath. The operation is performed by a neurosurgeon who specializes in surgery of the brain and spine.What testing is needed before surgery?
Before surgery, the precise area of the brain wherein the seizures originate from will need to be diagnosed. This may include:- MRI: An MRI uses large magnets, radio waves, and a computer to make images of the inside of the body.
- CT scan: This test uses a series of X-rays and a computer to create images of the inside of the body.
- EEG (outpatient): This test records the brain's electrical activity through sticky pads (electrodes) attached to the scalp.
- EEG (inpatient): Some patients may require a longer EEG to record electrical activity in which case a stay in the epilepsy monitoring unit will be required.
- MEG Scan: MEG, or magnetoencephalography, is a noninvasive test used to localize seizures and abnormal activity within the brain using magnetic sensors.
