Based on Surgical Procedure, the Intraoperative Neurophysiological Monitoring Market segmentation includes Orthopedic, Urology, Spinal, Neurovascular, and Otolaryngology Surgery. The Spinal segment held the majority share in 2022 contribution concerning the Intraoperative Neurophysiological Monitoring Market revenue. It can also evaluate the spinal cord and nerve roots after surgery to ensure proper cervical spine positioning. Its use in cervical spine surgery is wider than monitoring sensory tracts during the procedure. But SSEP changes during surgery are not always linked to postoperative neurological deficits because of its allegedly low specificity34, according to 33–35 studies. As a result, many researchers advise against using it as the sole monitoring modality in difficult cervical procedures.
The Intraoperative Neurophysiological Monitoring Market segmentation, based on type, includes Electroencephalography, Evoked Potentials, and Electromyography. The Electromyography segment dominated the market in 2022 and is projected to be the faster-growing segment during the forecast period, 2022-2030. The motor neurons that control muscles and the muscles are evaluated using a diagnostic procedure called electromyography (EMG). According to EMG results, there may be issues with nerve-to-muscle signal transmission, muscle dysfunction, or both positively impact the market growth.
The Intraoperative Neurophysiological Monitoring Market data has been bifurcated by surgery into Outsourced, In-House, and Tele-Health. The Outsourced segment dominated the market in 2022 and is projected to be the faster-growing segment during the forecast period, 2022-2030. Hospitals and healthcare facilities outsource their IONM needs due to cost-effectiveness and the availability of specialized service providers. IONM technology is constantly evolving and changing. Hospitals are relieved of the cost of purchasing and maintaining this equipment thanks to outsourcing. Additionally, training neurophysiologists is costly and time-consuming.
