Intraoperative Monitoring (IOM) Service

IOM is comprised of various procedures and modalities used during surgery to monitor neural pathways during high-risk neurosurgical, orthopedic, vascular, and peripheral nerve surgeries. IOM provides the surgeons with information to assist them in preventing damage and preserving functionality of the nervous system. The Michigan Medicine Intraoperative Monitoring (IOM) division covers over 1600 surgical cases per year.
IOM can detect potential damage to the brain, spinal cord, cranial and peripheral nerves during select surgeries. IOM can also facilitate mapping of the language and motor cortex. Suggested cases that may use IOM include:

    • Spinal instrumentation
    • Spinal deformity correction
    • Spinal cord tumors
    • Chiari malformations
    • Brain tumors
    • Epilepsy surgical resections
    • Aneurysms (clipping and coiling)
    • Arterial venous malformation (AVM) resections
    • Carotid endarterectomies
    • Peripheral nerve interventions

IOM modalities

  • Somatosensory Evoked Potentials (SSEP)
  • Motor Evoked Potentials (MEP)
  • Continuous Electroencephalography (EEG)
  • Auditory Brainstem Response (ABR)
  • Visual Evoked Potentials (VEP)
  • Electromyography (EMG)
  • Language and Motor mapping
