/or sensory deficits. 2 , 28 Real-time intraoperative neuromonitoring (IONM) has been described as a mandatory part of the procedure to prevent or minimize the risk of injury of the nerves hidden within the psoas muscle. 40 However, a growing number of publications suggest that transient neurological deficit, including psoas weakness and lumbar plexus dysesthesia, occurs despite neurophysiological surveillance. 14 , 32 , 40 The goal of this retrospective, single-center study was to investigate the incidence of neurological complications in minimally invasive LLIF without

(DSA), micro-Doppler (MD) ultrasonography, indocyanine green (ICG) fluorescent videoangiography, and intraoperative neuromonitoring (IOM). 2 IOM is routinely established in neurosurgical procedures for intracranial and spinal pathologies, including brain, skull base, or spinal tumors and degenerative diseases such as scoliosis operations. This particularly concerns the resection of space-occupying lesions within close proximity to the central region and/or ascending/descending sensorimotor fiber tracts. In this area, IOM has proven useful in improving the extent of

adult population, 2 , 4 , 5 gross-total resection (GTR) is pursued in the majority of cases. 1 , 6 In more infiltrative pathologies, i.e., astrocytoma, a subtotal resection (STR) may be adequate to reduce resection-associated neurological injury. To mitigate the exceedingly high neurological deterioration rates associated with the excision of intramedullary tumors, the use of intraoperative neuromonitoring (IONM) has become an imperative adjunct to their resection. Motor evoked potentials (MEPs), somatosensory evoked potentials (SSEPs), electromyography, and D

T he microsurgical resection of motor-eloquent gliomas requires avoidance of surgery-related motor deficits while achieving a maximum extent of resection (EOR) for optimal oncological treatment. 1–4 The gold standard technique for the surveillance of motor functions is intraoperative neuromonitoring (IONM), and the reliability and validity of this method are commonly accepted. 5–9 Additionally, tractography offers the opportunity to visualize the corticospinal tract (CST) and is regularly used by many neurosurgeons to get a better idea of subcortical anatomy

Unfavorable outcomes such as facial paralysis and deafness were once unfortunate probable complications following resection of acoustic neuromas. However, the implementation of intraoperative neuromonitoring during acoustic neuroma surgery has demonstrated placing more emphasis on quality of life and preserving neurological function. A modern review demonstrates a great degree of recent success in this regard. In facial nerve monitoring, the use of modern electromyography along with improvements in microneurosurgery has significantly improved preservation. Recent studies have evaluated the use of video monitoring as an adjunctive tool to further improve outcomes for patients undergoing surgery. Vestibulocochlear nerve monitoring has also been extensively studied, with the most popular techniques including brainstem auditory evoked potential monitoring, electrocochleography, and direct compound nerve action potential monitoring. Among them, direct recording remains the most promising and preferred monitoring method for functional acoustic preservation. However, when compared with postoperative facial nerve function, the hearing preservation is only maintained at a lower rate. Here, the authors analyze the major intraoperative neuromonitoring techniques available for acoustic neuroma resection.

I n the United States, the vast majority of pediatric deformity surgeries are performed while using intraoperative neuromonitoring (IONM). If reliable transcranial electric motor evoked potentials (TceMEPs) are present, they can be used intraoperatively as a substitute for performing the wake-up test. 1 However, multiple factors may influence the ability to generate baseline evoked potentials in certain pediatric populations. 1 , 2 , 12 Because of their associated risks of complete or partial paralysis, surgical procedures that may benefit from the use of

R esection of benign peripheral nerve sheath tumors (BPNSTs) carries the risk of neurological worsening, including new or worsened neuropathic pain or paresthesias, numbness, or weakness. Rates of reported postoperative deficits vary but often approach 30%. 1–4 With less-experienced surgeons often excluded from these reports, postoperative deficits may be underestimated. Intraoperative neuromonitoring (IONM) is thought by some to be an essential tool during resection of BPNSTs. However, little is known about the risks or benefits of using IONM. Routine use of
