Study Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Measuring Hearing Thresholds with Electrophysiological Tests
Time Frame: 6 years
Participants' hearing thresholds and cochlear microphonics evaluated by using Auditory Brainstem Responses and Otoacoustic Emissions.
Evaluating Middle Ear Pathologies
Time Frame: 6 years
Participants' middle ear pathologies evaluated by using Tympanometry
Evaluating Hearing Thresholds by Using Behavioral Tests
Time Frame: 6 years
Participants' reactions to sounds were assessed using Free Field Audiometry or headphones. These evaluations were conducted initially at the time of diagnosis and subsequently after the patients had started using hearing aids.
Secondary Outcomes
No secondary outcomes reported
