Abstract | BACKGROUND: METHODS: Eighteen patients (12 female and six male patients) with facial palsy and contralateral hyperkinesis were injected with 112.5 units (0.9 ml) of Dysport ( botulinum toxin type A) distributed evenly in the muscles of the perioral area. The patients were examined at 14, 28, 42, 56, 90, 150, and 180 days after the injection. Patients evaluated the degree of improvement at each time point. In addition, three evaluators made static (relaxed state) and dynamic (maximum contraction while smiling) assessments using a series of measurements obtained with a digital caliper, and the mean was used as the reference value. RESULTS: The quantitative analysis demonstrated a significant reduction in hyperkinesis that lasted approximately 180 days. There was a significant or moderate improvement in most of the cases. All of the patients were very satisfied with the treatment. Adverse events were short-lived (mainly during the first 15 days) and related to difficulty in drinking without liquid loss (nine of 18) and difficulty in chewing without food loss (three of 18). CONCLUSION:
