ASNM’s webinar series provides timely information of special interest to professionals working within the IONM industry and those seeking to learn more about this evolving area of practice. Webinars are included as part of ASNM’s membership and are a worthwhile member benefit. Non-ASNM members can purchase individual webinars. Webinar sessions are presented in "real time” via the Internet. Participants view webinar materials online while listening to the concurrent audio portion of the presentation via their computer audio system. All ASNM webinars are approved for one (1) credit hour of continuing education for ASNM-CEUs.

2018 Webinars 

Essentials of Intraoperative Auditory Brainstem Response Monitoring

Wednesday, August 22, 2018 
7:00 PM Eastern

Lawrence Wierzbowski AuD, DABNM, FASNM

President, Avatrode, LLC

IONM Consulting and Education


Approved for (1) hour of ASNM-CEUs

This activity was planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of Interstate Postgraduate Medical Association and ASNM. The IPMA is accredited by the ACCME to provide continuing medical education for physicians.

Credit Designations
The Interstate Postgraduate Medical Association designates this live activity for a maximum 1.0 AMA PRA Category 1 Credit(s)TM. Physicians should claim only the credit commensurate with the extent of their participation in the activity.


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.


 On completion of the Webinar you will be able to: 


  1. Describe basic anatomy of the auditory system.
  2. Define factors from the outer, middle and inner ear that might affect brainstem auditory evoked response (BAER) signal acquisition.
  3. Identify and gain a basic understanding of an Audiogram
  4. Basically describe auditory neural pathways and the brainstem nuclei that generate BAER waveforms    
  5. Identify some surgical procedures described in the literature that generally use BAER monitoring
  6. Recognize auditory neural and vascular structures that could be at risk during various surgeries that utilize BAER monitoring.
