Mitochondrial myopathy presenting as temporomandibular dysfunction.

J E Van Sickels, A B Gruber, K S Kagan-Hallet

    Journal of Oral and Maxillofacial Surgery : Official Journal of the American Association of Oral and Maxillofacial Surgeons

    Summary

    Facial pain may indicate underlying systemic myopathy, not just temporomandibular dysfunction. Early diagnosis of hereditary myopathies like mitochondrial myopathy is crucial for effective treatment.

    Area of Science:

    • Neurology
    • Genetics
    • Pathology

    Background:

    • Orofacial pain is often diagnosed as temporomandibular dysfunction.
    • Systemic myopathies can present with facial pain symptoms.

    Observation:

    • Three patients with orofacial pain initially diagnosed with temporomandibular dysfunction underwent muscle biopsies.
    • Biopsies revealed underlying pathologic abnormalities, suggesting a different diagnosis.

    Findings:

    • A number of patients with facial pain may have an undiagnosed systemic myopathy.
    • This myopathy can be hereditary with unusual inheritance patterns.
    • Mitochondrial myopathy is one example of such a condition.

    Implications:

    • Clinicians treating facial pain should consider the possibility of underlying systemic myopathies.

  • Awareness of hereditary myopathies is essential for accurate diagnosis and management.
  • Further research into the genetic basis and presentation of myopathies causing facial pain is warranted.
