Unexpected ABR Results in Patients Suspected With Auditory Neuropathy Spectrum Disorder

This study aimed to assess the clinical evaluations and potential underlying pathologies in patients diagnosed with Auditory Neuropathy Spectrum Disorder (ANSD) who exhibited unusual results in audiological tests. The research involved the retrospective analysis of audiological tests of 11 patients conducted by expert audiologists at Istanbul Medipol Mega Hospital between 2010 and 2020. These patients displayed abnormalities in their Auditory Brainstem Response (ABR) tests. The study sought to investigate patients with ANSD who presented atypical audiological findings, shedding light on the associated clinical aspects and potential causes of such anomalies.
