Bilateral Dislocation of Temporomandibular Joint Induced by Haloperidol Following Suicide Attempt: A Case Report

Drug induced dystonic reactions are among common presentations of patients in emergency departments, and typically occur with antidopaminergic agents as their extra-pyramidal side effects. dystonic reactions usually occur within the first few hours or days after commencing a drug or dose increase. unlike other extra-pyramidal side effects, a patient may experience acute dystonic reactions (adrs) with the administration of just a single dose. oromandibular dystonia is a subtype of dystonia which can present with perioral manifestations. in extreme cases, it can lead to temporomandibular dislocation. haloperidol, as a high potent typical antipsychotic drug, can induce dystonia with blocking d2 dopamine receptors. the present paper reports a case of bilateral dislocation of temporomandibular joint following ingestion of haloperidol in a suicidal attempt in a 17 years old girl.
