For ear, nose and throat medicine

Ear symptoms without an otological correlate

The connection is better supported than dentistry often portrays it – and weaker than it appears in advertising. Both are stated here.

You know these patients

Tinnitus, ear pressure, otalgia, globus sensation or dizziness without an otological correlate. Tinnitus that changes with chewing, clenching or jaw movement.

The connection

What has been measured

  1. 01Measured / described

    The figure

    A meta-analysis finds roughly 2.2-fold increased TMD odds in tinnitus patients. Aural symptoms – ear fullness and pressure, hearing loss, tinnitus, dizziness – are common in TMD. Both are associations; causation has not been shown.

  2. 02Measured / described

    The reproducible bedside finding

    If tinnitus can be modulated by jaw movement, clenching or palpation of the masticatory muscles, this is a somatosensory component – regardless of how the causal chain runs in detail. This finding can be tested on the patient and needs no device.

  3. 03Measured / described

    The anatomical pathway – and its status

    The discomalleolar ligament connects the disc and capsule of the temporomandibular joint to the malleus through the petrotympanic fissure. This is anatomically described; its role in symptom development is hypothesis, not evidence. We present it as such.

  4. 04Where the evidence ends

    Where the evidence ends

    The data for otological symptoms are inconsistent. We do not predict whether or how tinnitus will change – with this body of evidence, that cannot honestly be promised.

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

  • Ear-related complaints without ENT findings, especially with jaw or neck signs
  • Tinnitus that can be modulated by jaw movement
  • Otalgia with a normal eardrum and tender masticatory muscles

Not worthwhile

  • Before otological work-up is complete
  • With sudden hearing loss, acute vertigo or other red flags
  • With the expectation of a tinnitus prognosis

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.
