BERA

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.

Indications-

  • 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

  • Threshold Estimation BERA / ABR – This helps in estimating hearing levels
  • High Rate BERA / ABR – This helps in differentiating cochlear versus Retrocochlear involvement in hearing loss
  • Bone Conduction BERA / ABR – This helps in estimating bone conduction hearing levels.
