title: Efficacy and complication of botulinum toxin injection in palatal myoclonus: experience from a patient.
abstract: We report the outcome of botulinum toxin injection for essential palatal myoclonus, given on two occasions over a period of one year, in an eight-year-old boy, the youngest patient treated with botulinum toxin to date. Though there was significant relief of ear clicks each time after the injection, he developed severe palatal palsy following the second injection, which persisted for a month. We suggest that appropriate caution needs to be exercised when repeating botulinum toxin injections for palatal myoclonus in children.
