Essentials of Intraoperative Auditory Brainstem Response Monitoring

Lawrence Wierzbowski AuD, DABNM, FASNM
President, Avatrode, LLC
IONM Consulting and Education

Since the first published description of the auditory brainstem response (ABR) by Jewett and Williston in 1971, there have been hundreds of published works on both clinical and perioperative ABR applications. Intraoperatively, the eighth cranial nerve is in jeopardy of being injured during microvascular decompression surgery. Auditory function preservation is enhanced by ABR monitoring during resection of small vestibular schwannomas.  Surgical manipulation of the brainstem during excision of large cerebellar pontine angle tumors has been monitored by ABR to detect any deleterious effect to the brainstem auditory pathways that might occur. 

Interpretation criteria for the auditory brainstem response is available from several published guidelines that are based on the literature mentioned above but what are the “other” factors we encounter daily in the operating room that we need to consider as well.


Neuromonitoring during SCS Placement: Physiological Basis

Director, IONM
Associate Professor, Anesthesiology, Rush University Medical Center

This lecture will describe, in detail, the common IONM methodologies that are used during the placement of SCS leads as well as the physiology behind those methods. Common methods include the use of antidromic activation of the alpha-motor neurons via stimulation of the dorsal columns and the use of dorsal column collisions to lateralize the placement of leads. With new stimulation patterns the utilization of these techniques may be more important given standard awake lateralization cannot be used due to lack of standard clinical markers. Additionally, the physiology behind any IONM technique is critical to understand to both know the benefits and limitations of each technique. 

Jay Shils, PhD, D.ABNM, FASNM

Intraoperative Neuromonitoring for Neuromodulation Procedures

Steven M. Falowski, MD, FAANS
Director, Functional Neurosurgery
St. Lukes University Health Network

The use of IONM for neuromodulation is not only used as a modality for safety, but is also used as a confirmation of lead placement with spinal cord stimulators. It is this factor that is most important given the need to have a marker of proper lead position in an asleep patient. Newer protocols have also determined methods of lead placement with DRG stimulators. Newer research has examined the spinal and cortical responses of various programming waveforms, and has given an ability to have human spinal recording data.

Minimizing Confounding Variables and IONM Conflicts

Christopher Pace, PhD, CNIM
Chief Clinical Officer, Neuro Alert Monitoring Services
Director, Center for Electroneurodiagnostics

IONM is a helpful tool employed during spine surgery to reduce the risk of injury to delicate spinal cord and nerve pathways. IONM can, furthermore, be used to evaluate the integrity of bony structures into which metal implants have been placed (i.e. pedicle screw testing) and, also, to identify and localize neural structures. We may not always appreciate (take for granted) how many variables we are evaluating, and how much information we are integrating in order to provide the highest quality and value of IONM data. This presentation is intended to give an overview of IONM for major spine procedures and, through general discussion and case studies, to expand on this basic understanding. It will explore how specific technical, physiologic, anesthetic, surgical and communication variables (-based issues) impact IONM.

Navigating Legal Issues in Neuromonitoring

Eric D. Fader
Day Pitney LLP

There is considerable confusion and disagreement regarding many of the legal and regulatory requirements pertaining to IONM. The laws of different states and the federal government differ and are constantly changing, and IONM providers must also navigate insurance carriers’ and hospitals’ requirements, and relationships with their own or outsourced personnel, in order to bill and get paid for their services while complying with applicable law. State licensure and delegation issues, and what constitutes the “practice of medicine” in a given state, can vary considerably, and contractual dealings with customers, employees and contractors, and billing and IT service providers can also be complex. This webinar will discuss some common legal issues facing IONM providers and, where possible, offer possible solutions.

Utility of Spontaneous EMG, SSEPs, and MEPS to Monitor the Functional Integrity of Spinal Nerve Roots and Plexusesx

W. Bryan Wilent, PhD, DABNM
Vice President of Education and Training
Sentient Medical Systems

During most orthopedic procedures SSEPs and MEPs are utilized primarily to assess conduction of the spinal cord pathways, but they obviously monitor the entire pathway, from peripheral nerve to brain or from brain to muscle, and can detect a functional compromise in specific nerve roots or plexuses. The usage of these modalities for monitoring peripheral function is debatable, however, because their utility is procedure/patient specific and the sensitivity and specificity is technique dependent; therefore, the IONM team should be aware when peripheral structures are most at risk and optimize the IONM accordingly

Bryan Wilent

IONM Considerations in Endonasal Skull Base Surgery

Adam T. Doan, DC, DABNM
Director of Clinical Services
Safe Passage Neuromonitoring

Minimally invasive intracranial surgery continues to gain popularity, as advances in visualization, instrumentation and anatomical understanding allows the endoscope to be used to approach the skull base. The endonasal endoscopic route to the skull base can now be used to gain access from the crista galli to the odontoid process. It behooves the neuromonitoring team to appreciate the different neurovascular structures that may be encountered, in order to devise a specific multimodality strategy unique to the patient and the surgery. Knowing the rationale and limitations of the plan optimizes the information collected and communicated.

Adam T. Doan, DC, DABNM

Variables in Pedicle Screw Monitoring

Lawrence R. Wierzbowski, AuD, DABNM, FASNM
Neurological Monitoring Services

It is important to take anatomical, neurophysiological, surgical technique, surgical instrument conductivity and many other variables into consideration when recording triggered and free running electromyographic (EMG) signals in the operating room during spinal fusion with pedicle screw instrumentation. During the electrical evaluation of either the pedicle hole or the subsequent pedicle screw a “threshold” stimulation is commonly employed using the minimum amount of current to provoke an observable and repeatable compound muscle action potential (CMAP). Interpretation and alarm criteria for pedicle screw integrity using stimulated electromyography is usually based on the several published guidelines but are there “other” factors that we need to consider as well?
