The long-term effect of oromaxillofacial trauma on the function of the temporomandibular joint

Thirty patients with temporomandibular disorders (TMD) after trauma to the orofacial region were followed for 6 months. They were assessed at 10 days, 1 month, and 6 months. It was found that patients with combined fractures of the mandible and condyle showed more effects on function of the temporomandibular joint after 1 month than patients with condylar fracture only. This difference was not so apparent after months. Patients with trauma but no fracture showed similar effects to those with non-condylar fractures. There was a tendency for arthrogenous patients to develop myogenous problems with time. A group of patients with TMD but no trauma, showed more favourable long-term response to conservative treatment. Long-term follow-up of these patients for TMD problems is recommended.
