Mandibular hypomobility/ankylosis

Condylar fracture sequelae resulting in hypomobility or ankylosis include a wide range of conditions involving the temporomandibular joint (TMJ):

  • Internal derangements of the TMJ
  • Malposition of the condylar head
  • Shortening of the mandibular ramus
  • Resorption of the condylar head

On the left, a case of TMJ ankylosis is shown.

These conditions can have different impact on the function of the mandible, symmetry of the face, and occlusion. The altered anatomy of the condylar area, functional, and esthetic findings will determine the treatment modality.

Besides the routine patient history and health status, the examiner should obtain details on previous treatment or treatments (eg. dates, procedures and complications).

Physical examination should focus on facial asymmetries, limitation of mandibular movements, malocclusion, and pain.
