Background: BERA is an objective study for assessing hearing loss on patients with inconsistent responses on pure tone audiogram. BERA is a non-invasive and the most cost-effective method for diagnosing retrocochlear lesion, not affected by sedation, anesthesia or age. Which helps to identify retrocochlear hearing loss. It is impossible to perform pure tone audiometry on infants and children.
Methods and Aim: This is a cross sectional prospective cohortHospital based study, review of 50 patient subjected to BERA for SNHL in any age group referred to department of ENT Vijayanagara institute of medical sciences, Bellary. Our aim is to find out its applications on objective test in cases of inconsistent response to pure tone audiometry
Result: Pure tone audiometry was done in all cooperative cases and found hearing loss of different severity, few with inconsistent responses, few retrocochlear pathology and also helps in identifying malingering as BERA as an objective test.
Conclusion: BERA is useful in finding hearing thresholds in patients with inconsistent response to pure tone audiometry.
