Presbycusis

Degenerative disorder of the cochlear resulting in hearing loss

Aetiology

  • Typically seen in old age, although onset can be variable
  • Can be due to:
    • Loss of outer hair cells - environmental noise toxicity over time is a major factor
    • Loss of ganglion cells
    • Strial atrophy

Clinical presentation

  • Gradual onset hearing loss

Investigations

Audiometry

  • Higher frequencies affected most
  • Usually sensorineural hearing loss

Management

  • High-frequency-specific hearing aid
