Summary

This case report details bilateral temporomandibular joint (TMJ) ankylosis and a rare bifid mandibular condyle in a patient with a history of trauma. The study reviews treatment options for TMJ ankylosis and bifid condyles.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthodontics
  • Radiology

Background:

  • Temporomandibular joint (TMJ) ankylosis is a debilitating condition characterized by restricted jaw movement.
  • Bifid mandibular condyles are rare anatomical variations that can affect TMJ function.
  • Trauma is a significant etiological factor in the development of TMJ ankylosis.

Observation:

  • A unique case of bilateral TMJ ankylosis is presented in a patient with a 39-year history of trauma.
  • Radiographic examination revealed a mushroom-shaped right condyle and a bifid left condyle.
  • The patient presented with significant limitations in jaw mobility.

Findings:

  • The case highlights the coexistence of TMJ ankylosis and a bifid mandibular condyle, a combination rarely documented in medical literature.

Related Experiment Videos

  • The specific morphology of the condyles (mushroom-shaped and bifid) suggests complex etiopathological processes.
  • The long-standing history of trauma likely contributed to the development of the observed TMJ pathology.

    • Implications:

    • This case underscores the importance of considering rare anatomical variations and long-term consequences of trauma in TMJ disorders.
    • Understanding the presentation of bifid condyles alongside ankylosis can aid in accurate diagnosis and tailored treatment planning.
    • Further research into the etiology and management of such complex TMJ conditions is warranted to improve patient outcomes.
