AbstractBotulinum toxin (BTX) has been used successfully to treat various movement disorders, and is increasingly used for many other medical conditions. Sialorrhoea is a disabling symptom in many neurological patients including those with Parkinson's disease, stroke and amyotrophic lateral sclerosis (ALS). BTX has recently been shown to be effective for treating sialorrhoea. We report an ALS patient who developed recurrent jaw dislocation following BTX treatment for sialorrhoea to highlight the observation that intraparotid BTX may be complicated by jaw dislocations in some at-risk ALS patients. Clinicians using BTX to treat sialorrhoea in ALS need to be aware of this potentially serious complication.
