DESCRIPTION:
Asymmetric hearing sensitivity and low word recognition (WR) scores are accepted signs of retro-cochlear ear disease. Determining when WR performance is low can be accomplished using clinical intuition or computational methods. We evaluated whether a computational method for identifying vestibular schwannoma based on hearing asymmetry could be improved by incorporating WR performance measures.
LEARNING OBJECTIVES
Upon conclusion of this activity, participants should be able to:
- Identify 3 factors that influence the observed WR test score.
- Explain the difference between the standardized difference score approach with the traditional classification approach for determining when a word recognition score is unexpectedly low.
- Explain why computational methods using the combination of unilateral hearing loss and reduced word recognition scores does not improve vestibular schwannoma detection better than methods based on hearing asymmetry alone.
PRESENTER BIO
David Zapala earned his B.A. from California State University at Fullerton, M.S. from Utah State University, and Ph.D. from the University of Memphis. Early in his career he developed the Infant Hearing Center, and Hearing and Balance Center at Methodist Healthcare in Memphis and served as a clinical professor in Otolaryngology at the University of Tennessee. He is currently a Senior Consultant and Chair of the Audiology Section at the Mayo Clinic in Florida and an Associate Professor of Audiology in the Mayo School of Medicine. Dr. Zapala is directly involved in patient care; resident, fellow and post-doctoral mentorship; and clinical research. He has over 150 professional presentations and 68 publications in the areas of auditory and vestibular research. He has also mentored 22 doctoral or post-doctoral fellows over the course of his career. He has served on the boards of the America Board of Audiology, the American Academy of Audiology, The American Balance Society, and was a founding member of the Tennessee Academy of Audiology. His awards include: Distinguished Service Award - Tennessee Academy of Audiology (1997), Edward Dalstrom Distinguished Service Award - Mid-South Lions Sight and Hearing Service (2001), Distinguished Service Award - American Board of Audiology (2007), Jerger Award for Mentored Clinical Research (Mentor),2009 - American Academy of Audiology (2009), Outstanding Alumnus of the Year - School of Communication Sciences and Disorders, University of Memphis (2013), Service Award - American Academy of Audiology (2013), Distinguished scholar and fellow - National Academy of Practice,(2016), Distinguished Clinician of the Year - Mayo Clinic (2017), Honors of the Academy - American Academy of Audiology (2018), Distinguished Service Award - American Academy of Audiology Foundation (2018). The overarching aim of his current research is to build healthcare delivery systems that improve healthcare providers’ ability to safely qualify individuals seeking non-medical treatments for hearing, balance and dizziness difficulties. Dr. Zapala was recognized at the Sixth Annual Mayo Clinic Value Symposium for his work streamlining the division of labor between audiologist and otolaryngologist providers based on the presenting needs of the patient. His work is supported by the Mayo Clinic, the Knowles Foundation and NIDCD (R21-DC013115-0A1).

Heather Clark, Ph.D. | Dr. Clark is the Chair of Speech Pathology in the Department of Neurology and Associate Professor in the College of Medicine at the Mayo Clinic in Rochester, Minnesota. She is board-certified by the Academy of Neurologic Communication Disorders and Sciences and is a Fellow of the American Speech-Language-Hearing Association. Her clinical responsibilities include differential diagnosis of communication and swallowing disorders in adults and children. She serves as co-investigator in several projects examining the nature of speech, language, and swallowing impairment in degenerative neurologic disease. Dr. Clark has served as a topic chair for the ASHA convention, program chair of the Conference on Motor Speech, and chair of the fall conference of the North Carolina Speech Language Hearing Association. |
Jill Gruenwald, Au.D. | Jill Gruenwald, Au.D., is the Audiology Supervisor at Mayo Clinic. Her current areas of clinical practice are adult diagnostics and cochlear implants with past experience providing hearing aid services and completing vestibular evaluations. She is a Fellow of the American Speech-Language-Hearing Association. |
| Gayla Poling, Ph.D. | Gayla L. Poling, PhD, is Director of Diagnostic Audiology at Mayo Clinic – Rochester, MN and Vice-Chair of Research in the Department of Otolaryngology. She received her undergraduate and master’s training in Speech and Hearing Science from The Ohio State University and completed her Clinical Fellowship at Henry Ford Hospital. She practiced as a clinical audiologist at Mayo Clinic prior to returning to Ohio State where she earned a PhD in Hearing Science. She completed postdoctoral training focused on translational research at the Medical University of South Carolina and Northwestern University. Her current research interest is on developing diagnostic tools focused on the early detection and prevention of hearing loss due to aging, noise and other environmental factors (ototoxicity). |
