A corpus callosotomy is the surgical separation of the right and left brain hemispheres. The corpus callosum is the largest pathway between the two cerebral hemispheres; this connection of white matter contains a bundle of nerve fibers.
A partial callosotomy divides the front two-thirds of the corpus callosum, leaving the back portion intact to retain more of the connection and brain’s communication. A complete callosotomy disconnects both the anterior and posterior portions of the corpus callosum from the right and left cerebral hemispheres.
The microsurgical technique (microscopes and small instruments are used) treats intractable epilepsy that is drug-resistant. Particularly seizures that start in one area of a hemisphere and then spread to the other hemisphere; by severing the pathway between the hemispheres, the abnormal electrical activity on one side is unable to travel to the other side and escalate the seizure.
Specific types of refractory (or unmanageable) epilepsy are most suited to this form of brain surgery:
Candidates for this type of brain operation will have tried anti-seizure medications and other conservative treatments before considering this form of epilepsy surgery.
At Neurological Surgery, P.C. (NSPC), a team of medical specialists such as neurosurgeons, neurologists, neuropsychologists and neuro-epileptologists will help determine if a microsurgical corpus callosotomy procedure will help minimize the spread of electrical discharges contributing to your seizures.
Our brain imaging experts use a variety of tools to pinpoint the brain abnormalities:
During the corpus callosotomy procedure, the patient is under general anesthesia and a portion of the scalp is shaved. An experienced neurosurgeon carefully performs a craniotomy to open up the cranium and the dura (membrane that covers the brain) to view the corpus callosum. With microsurgical instruments, the nerve bundle is segmented: the anterior portion for a partial callosotomy or the entire nerve fiber cluster for a complete callosotomy. The dura, cranium and scalp are then closed up.
