For hearing care professionals

When tinnitus persists despite fitting

You notice it before anyone else: the fitting is right, the readings are correct – and the tinnitus remains. For some of these people there is an explanation that does not lie in the ear.

You know these patients

Tinnitus or ear pressure that does not improve with fitting. Tinnitus that changes with chewing, clenching or jaw movement. A feeling of pressure without a clear audiological correlate.

The connection

What has been measured

  1. 01Measured / described

    The figure

    In tinnitus patients, the TMD odds are roughly 2.2-fold higher; aural symptoms are common in TMD. Association, not causation – but one large enough to consider when a fitting fails to help.

  2. 02Measured / described

    The finding you can check yourself

    Ask the client to clench their teeth firmly, push the lower jaw forward and open wide. If the tinnitus changes in loudness or pitch, a somatosensory component is present. This is a one-minute test without a device.

  3. 03Where the evidence ends

    Where the evidence ends

    The data on otological symptoms are inconsistent. A hearing aid does not reach the jaw component – but whether and how much tinnitus changes with jaw treatment varies from person to person and cannot be predicted.

Indication

When a referral is worthwhile

First, and without exception: red flags and unclear findings belong in specialist work-up, before any functional diagnostics. The CMD perspective complements, it does not replace.

Worthwhile

  • Tinnitus or ear pressure that changes with jaw movement
  • No benefit despite correctly fitted devices
  • Additional jaw or neck signs

Not worthwhile

  • Before ENT work-up
  • As a replacement for audiological care

Your patient remains yours.

After the assessment or after regulation is complete, we always refer back to you. We only provide further treatment at your explicit written request.
