Intraoperative neuromonitoring (IONM) provides critical nervous system insight during surgery. This allows surgeons to prevent or reverse neural damage, improving surgical outcomes.

Area of Science:

  • Neurosurgery
  • Neurology
  • Surgical Monitoring

Background:

  • Intraoperative neuromonitoring (IONM) has been utilized for over 25 years in surgical procedures.
  • IONM offers critical insights into the nervous system during operations, enabling surgeons to prevent or reverse neural insults.

Purpose of the Study:

  • To highlight the role and benefits of IONM in surgical procedures.
  • To explain how IONM aids in identifying and mitigating surgical risks to the nervous system.

Main Methods:

  • Utilizing electrophysiological tests such as electroencephalography, electromyography, and various evoked potentials (somatosensory, auditory, motor).
  • Monitoring signal integrity during surgeries with inherent nervous system risks.

Main Results:

Related Experiment Videos

  • Deterioration in IONM signals indicates a potential surgical insult and correlates with a higher risk of postoperative deficits.
  • Real-time risk identification through IONM facilitates timely corrective surgical actions.
  • IONM is also employed to assess nervous system anatomy and function in response to surgeon-posed questions.

Conclusions:

  • Intraoperative recordings via IONM are now standard in numerous surgical interventions.
  • The appropriate application of IONM demonstrably enhances surgical outcomes.
