In the Division of Intraoperative Monitoring, our goal is to provide the highest-quality monitoring techniques to patients undergoing surgery. Our services include peripheral nerve and root stimulation; electromyography (EMG); facial EMG; pelvic floor EMG; auditory brainstem, somatosensory, and visual evoked potential (EP) studies; transcranial motor evoked potentials (MEP); direct motor cortical stimulation and cortical phase reversal testing; direct spinal cord motor tract recordings; neuromuscular junction testing (TOF); orbicularis oculi (blink) reflex; and bulbocavernosus reflex.

Our experts specialize in the care of children and adults with the following conditions:

• brain and brainstem tumors
• spinal cord tumors and compressions
• scoliosis
• vertebral deformities, congenital and acquired
• nerve tumors, compression, and entrapment syndromes
• brachial plexus abnormalities, congenital and traumatic
• cervical and lumbar radiculopathy
• spinal cord stimulator implantation
• cervical, thoracic, and lumbar spinal stenosis
• vascular stenosis, cranial and spinal
• cranial nerve compression

Intraoperative Neurophysiological Monitoring

In the operating room, our physicians and technologists work closely with surgeons, providing patient protection and real-time feedback throughout surgical procedures. Our intraoperative neurophysiological monitoring service strives to provide the best in patient care and safety.

Each year, our team monitors thousands of procedures involving the central and peripheral nervous systems to avoid preventable complications. These include anterior or posterior cervical decompression and fusion; anterior or posterior lumbar spinal fusion; scoliosis deformity correction; surgery for brain, spinal cord, and peripheral nerve tumors; carotid endarterectomy; epilepsy surgery; tethered cord release; selective rhizotomy for spasticity; and implantation of spinal cord stimulators.

Modalities we commonly use include studies of somatosensory EPs (SEPs), motor EPs, corticospinal motor EPs (D wave), auditory brainstem EPs, cortical phase reversal, functional cortical mapping, free-running EMG, triggered EMG, and facial lateral spread.
