The NS-IOM-E is a touch-screen, user-friendly intraoperative neuromonitoring system available in 4 or 8 channels, which has wide applications for use during different types of surgery.

This device helps reduce the risk of nerve damage during surgery and identify nerve functions before the end of surgery through monitoring of triggered EMG activities in multiple cranial and peripheral nerves. NS-IOM-E is applicable for Facial Nerve, Thyroid, Spinal, ENT and other general surgeries.

Smart IOM can support surgeons with the following functions:

  • Identification of nerve and tissues
  • Confirmation of injected nerves and their locations
  • Monitoring of nerve integrity in real-time such as:
    • Thyroidectomy: vagal nerve, SLN, RLN detection during head and neck surgery by monitoring vocal cord muscle response from stimulus
    • Facial nerve monitoring during ENT, oral and maxillofacial surgery by observing the activities of orbicularis oris and orbicularis oculi muscles
    • In SPR surgery, the rootlets that cause spasticity can be identified by examining EMG responses of muscles in the lower extremities when each rootlet is electrically stimulated
    • Other motor nerves during various surgeries
