CRUZADO, Lizardo; NUNEZ-MOSCOSO, Patricia; GARIBAY-HUAMANI, Mercibel  y  VILLAR-SALAS, Alicia. Recurrent temporomandibular luxation secondary to dystonia induced by antipsychotics. Rev Neuropsiquiatr [online]. 2016, vol.79, n.3, pp.180-185. ISSN 0034-8597.

Antipsychotic-induced acute dystonia remains as a common presentation in psychiatric emergency services. However, luxation of the temporo-mandibular joint, as a sequel to oro-mandibular dystonia is an unusual clinical occurrence. We report the case of a 20-years-old-woman who received intramuscular haloperidol after two crisis of psychomotor agitation with persistent suicidal risk, developed then oro-mandibular dystonia and, as a result of which, suffered unilateral temporo-mandibular dislocation. A recommendation is made not to repeat a parenteral administration of high-potency antipsychotics to patients who have suffered dislocation of the temporo-mandibular joint as a result of secondary dystonia to these drugs. Additionally, we examine the possibility that, due to the massive and growing use of atypical antipsychotics at the present time, the training of psychiatrists about prediction and management of adverse effects of neuroleptics may be neglected.
