Differential diagnosis

Clinical performance of audiology diagnostic tests

The value of the information content in a complete diagnostic evaluation lies in the ability to differentiate and diagnosis a hearing loss. The amount of diagnostic information contained in the assessment will increase the probability of an accurate diagnosis. The analysis of a comprehensive diagnostic based test battery designed to differentiate cochlear from retrocochlear site-of-lesion will guide clinical decision and care pathway to diagnose auditory disorders, otologic diseases, and vestibular dysfunction.

Some common diagnosis are:

  • Exposure to loud noise
  • Head trauma
  • Virus or disease
  • Autoimmune inner ear disease
  • Hearing loss that runs in the family
  • Aging (presbycusis)
  • Malformation of the inner ear
  • Meniere’s Disease
  • Otosclerosis - a hereditary disorder in which a bony growth forms around a small bone in the middle ear, preventing it from vibrating when stimulated by sound.
  • Tumors
  • Perilymph fistula
  • Acoustic Neuroma
  • Malformation of outer ear, ear canal, or middle ear structures
  • Fluid in the middle ear from colds
  • Ear infection (otitis media - an infection of the middle ear in which an accumulation of fluid may interfere with the movement of the eardrum and ossicles
  • Poor Eustachian tube function
  • Perforated eardrum
  • Benign tumors
  • Impacted earwax
  • Infection in the ear canal
  • Foreign body in the ear
