See the list below:

  • Audiometry, including pure-tone and speech tests and immittance (tympanometry and acoustic reflex) tests, is mandatory. Testing can be directed by information gleaned from the history and physical examination. Obtaining those laboratory tests for which the results may influence the treatment plan is wise.

  • Auditory brainstem response testing and otoacoustic emissions (OAE) tests may provide additional information regarding the functional integrity of the auditory system.

    • OAE testing can provide information about cochlear function, and the auditory brainstem response can be used to assess auditory nerve function.

    • The auditory brainstem response and OAE results may also assist in diagnosing a functional hearing loss.

  • Vestibular tests are not mandatory and are obtained when indicated by the history and physical examination findings.
