Vestibular evoked myogenic potential testing for the diagnosis of conductive hearing loss: survey of pediatric otolaryngologists' knowledge and beliefs.

Abstract Objectives To assess physicians’ knowledge and beliefs regarding vestibular evoked myogenic potential (VEMP) testing in children. Methods A survey was delivered via email in html format to 1069 members of the American Academy of Otolaryngology – Head and Neck Surgery who identified as pediatric otolaryngologists. Study data were collected and managed using the Research Electronic Data Capture (REDCap) tools. Results 443 (41.4%) physicians opened the email. 190 (42.9% of opens) initiated the survey, of which 117 (61.9%) fully completed the survey of the physicians who responded to a question regarding knowledge of VEMP, 16% of respondents had never heard of the test. 16% of participants would use it in the setting of diagnosing pediatric conductive hearing loss. Responses regarding the youngest age at which VEMP is possible ranged from younger than 6 months through greater than 13 years of age. Beliefs regarding utility and reliability of VEMP varied, with ‘unsure’ as the most frequent response. Additionally, only 26% of pediatric otolaryngologists indicated some access to the test. Conclusion The knowledge and availability of VEMP testing in the pediatric otolaryngology community varies widely.
