About Epilepsy Neurosurgery
For patients with epilepsy who cannot attain good seizure control with medications, epilepsy surgery is an important option. Baylor College of Medicine's Department of Neurosurgery has been a recognized leader in the surgical treatment of epilepsy for more than 30 years.
Pre-Surgical Evaluation for Epilepsy
Before meeting with a Baylor neurosurgeon who specializes in epilepsy, patients are carefully evaluated a team of experts at the Baylor Comprehensive Epilepsy Center to determine whether a patient is a good candidate for epilepsy surgery, and which surgical procedure is best for that patient.
Non-Invasive Monitoring and Testing
The evaluation is personalized for each individual patient and typically includes several of the tests listed below, all of which are available at our center:
- Video electroencephalogram (EEG) telemetry in the Epilepsy Monitoring Unit (EMU)
- Advanced MRI, including functional MRI and diffusion tensor imaging (DTI)
- Neuropsychological testing
- Positron emission tomography (PET)
- Single-photon emission computed tomography (SPECT)
- Magnetoencephalography (MEG)
- WADA test
Neurosurgery for Epilepsy
In some cases, monitoring with non-invasive scalp electrodes is not sufficient to localize seizures. Electrodes can then be surgically implanted inside the skull, and recordings directly from the brain are monitored in the EMU to map out the seizure focus.
- Grid, strip and depth electrodes
- Stereo-electroencephalography (SEEG)
- Anterior temporal lobectomy
- Extratemporal resections
- Brain mapping, awake craniotomy
- NeuroPace® Responsive Neural Stimulator (RNS) - Our department was one of the first sites in the U.S. to participate in a clinical trial of RNS.
- Vagus nerve stimulation (VNS) therapy
- Multilobar resections
- Laser interstitial thermal therapy (LITT)
