Bilateral TMJ dislocation in a 23-month-old infant: a case report

Dislocation of the temporomandibular joint (TMJ) is rare in children. We present the second youngest case reported. Diagnosis was delayed owing to failure to recognize important clinical signs. We outline how this problem can be recognized and treated, and propose radiographic confirmation of the clinical diagnosis which is not necessary if there is no history of direct mandibular trauma. Two new clinical signs are demonstrated.

TMJ dislocation is of relevance to all dental professionals because it can occur in the dental chair and because dental professionals are often called upon to manage this condition.
