Neuroleptic-induced persistent "open mouth".
After prolonged exposure to butyrophenones, a patient with a paranoid psychosis showed an extrapyramidal motor disturbance which, phenomenologically, was very unusual and outlasted the medication. He involuntarily kept his mouth wide open all the time. Reasons for that symptom other than an induction by neuroleptics were not found.
