the brain is composed of billions of
cells called neurons they release electrical impulses these
impulses send messages that tell different parts of the body what to do
if a person has epilepsy some neurons may fire too rapidly and randomly send
many messages at the same time this overwhelms the brain and causes seizures
to reduce or stop seizures a pediatric neurosurgeon may perform a two-part
surgery to begin the first surgery the surgeon will make an incision in the
scalp which is the skin on the head a section of bone will be removed from the
skull so the brain can be seen the surgeon will place a grid with
electrodes on to the brain the electrodes will stay on the brain until
the second surgery to end the first surgery the surgeon
will put the bone flap back in place and close the scalp with staples the head
will be wrapped with a bandage after the first surgery the child will stay in the
hospital connected to a video EEG over the next few days the seizure activity
in the brain will be monitored 24 hours a day during this time a pediatric
epileptologists will work with the neurosurgeons to find the location of
the seizure activity in the brain if that part of the brain can be removed
without interrupting important functions like speech and movement the
neurosurgeon will perform another surgery to remove it during the second
surgery the neurosurgeon will open the scalp and remove the bone again the
electrodes will help the surgeon find the part of the brain where the seizures
are coming from then the part of the brain causing the seizures will be
removed after removing that part of the brain the surgeon will reattach the bone
flap to the skull then the scalp will be closed with sutures the child will remain in the hospital
for several more days to recover
