| Abstract | SUMMARY Background: The treatment of facial palsy aims to recover symmetry in both static and dynamic states, which are seriously affected in this condition. Previous studies mainly have emphasized surgical and invasive methods. The objective of this study is to evaluate the action of the botulinum toxin in reduction of the contralateral hyperkinesis of the perioral area in this pathology. Methods: Eighteen patients (12 female and 6 male) with facial palsy and contralateral hyperkinesis were injected with 112.5 U (0.9 ml) Dysport ® (Botulinum toxin type A Ipsen Limited, Berkshire, England) 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 utilizing a series of measurements made with a digital caliper, and the mean was used as the reference value. Results: The quantitative analysis demonstrated a significant reduction in the hyperkinesis that lasted approximately 180 days and significant or moderate improvement in most of the cases. All the patients were very satisfied with the treatment. Adverse events were short-lived and related to difficulty in drinking without liquid loss (9/18) difficulty in chewing without food loss (3/18). Conclusion: Injection of Botulinum toxin was effective in reducing muscular hyperkinesis in the hemiface opposite to affected by facial paralysis with mild and short-lasting side effects. |
