[Temporomandibular joint septic arthritis with secondary condylar resorption].

INTRODUCTION: Septic arthritis are serious infections rarely observed for the temporomandibular joint. They are mainly hematogenous or transmitted by contiguity. OBSERVATION: Our patient presents the case of an infection of the temporomandibular joint by maxillary sinusitis of dental origin further complicated by cerebral abscess and empyema. Initial treatment consisted of an endonasal and intraoral drainage, intravenous empirical antibiotic therapy, a close clinicoradiological monitoring, and rehabilitation following a long-term active physiotherapy. Furthermore, the patient reported the onset of a dental articulation disorder with a left side premature contact and right lateral open bite, corresponding to a significant left condylar resorption. DISCUSSION: This infectious disease is very rare for temporomandibular location; however, its general and functional outcome is determined by the precocity of the treatment. It is important to know the diagnosis and the associated symptoms even if they are not very specifically described. It is essential to consider the diagnosis when facing atypical pain of the temporomandibular joint associated with trismus.
