Tinnitus and the Masticatory System

  • Michael BehrEmail author


  1. 1.

    Epidemiologic data indicate a frequent association between temporomandibular joint disorders and tinnitus.

  2. 2.

    It is extremely unlikely that tinnitus is Directly caused by a mechanical relationship between the masticatory system and the middle ear.

  3. 3.

    Increased muscle tension of masticatory muscles may cause clonus of the palatine muscle via reflex muscle hypertension.

  4. 4.

    Increased muscle tension of masticatory muscles can influence tinnitus via somatosensory afferents.

  5. 5.

    In certain patients, occlusional appliances have been shown to normalize increased muscle tension and improve tinnitus, even if evidence for their efficacy is limited.
