Brainstem Evoked Response Audiometry(BERA) or Auditory Brainstem Response (ABR) is an objective electrophysiological and non-invasive method of hearing assessment. BERA / ABR evaluate both cochlea and brainstem auditory pathway integrity. Estimating hearing levels of difficult-to-test patients Evaluating patients with suspected Retrocochlear Pathology. Diagnosis of Auditory Neuropathy Spectrum Disorder. To Assess hearing in Congenital Malformations of Ear cases such as Microtia, Atresia, Stenosis of Ear Canal, Anotia, Ear Tags & Mondini deformity. To assess Functional Hearing Loss Types of BERA / ABR we use 1. Threshold Estimation BERA / ABR – This helps in estimating hearing levels. 2. High Rate BERA / ABR – This helps in differentiating cochlear versus Retrocochlear involvement in hearing loss 3. Bone Conduction BERA / ABR – This helps in estimating bone conduction hearing levels.
