Overview
Temporomandibular joint (TMJ) dislocation involves the displacement of the mandibular condyle from the articular fossa 1. This can occur acutely, for example, during medical procedures, or chronically 12.Diagnosis
Diagnosis is typically made clinically based on patient presentation and physical examination 1.
Radiographic imaging may be used to confirm the diagnosis and assess for associated fractures 1.Management
Acute dislocations are often managed with closed reduction 1.
Surgical interventions, such as eminectomy, are considered for chronic dislocations 2.Special Populations
Jaw dislocation can occur during general anesthesia, particularly with the placement of oral airways or nasogastric tubes 1.Key Recommendations
Closed reduction is a primary treatment for acute temporomandibular joint dislocations 1. (Evidence: Expert opinion)
Eminectomy is a surgical option for managing chronic mandibular dislocations 2. (Evidence: Weak)References
