Hearing Loss Diagnosis

Hearing Loss Diagnosis

Definition

Hearing loss diagnosis involves evaluating the type and degree of hearing impairment using specialized tests and tools. Early diagnosis helps identify the underlying cause, whethere it’s due to age, infections, noise exposure, or other medical conditions, enabling timely treatment or rehabilitation.

Purpose of Hearing Loss Diagnosis

  • To determine the type (conductive, sensorineural, or mixed) and severity of hearing loss

  • To identify underlying causes and contributing factors

  • To guide appropriate treatment, therapy, or hearing aid selection

  • To improve communication, quality of life, and overall ear health

Types and Methods of Diagnosis

Audiometry

  • Measures hearing sensitivity at different frequencies

  • Helps identify the degree and type of hearing loss

Tympanometry

  • Assesses middle ear function and eardrum mobility

  • Detects fluid, infection, or Eustachian tube problems

Otoacoustic Emissions (OAE)

  • Evaluates inner ear (cochlear) function

  • Commonly used for newborn hearing screening

Brainstem Auditory Evoked Response (BAER/ABR)

  • Assesses auditory nerve and brain pathway function

  • Helps diagnose neurological causes of hearing loss

Imaging & Medical Examination

  • CT or MRI scans for structural or nerve-related issues

  • Physical examination of ear canal, eardrum, and middle ear

Benefits of Hearing Loss Diagnosis

  • Enables early detection and intervention for hearing problems

  • Guides appropriate treatment or hearing aid fitting

  • Improves communication, social interaction, and quality of life

  • Prevents complications from untreated hearing loss
