The use of botulinum toxin-A as an adjunctive treatment for facial atrophic and hypertrophic scars after surgical correction

Background: Facial wounds, especially the ones lying perpendicular to the Lines of Langer, heal poorly. Several methods have been attempted to rectify this, but most of them do not target the underlying pathological process of scarring. Botulinum Toxin-A (BTA) has been successfully used for atrophic and hypertrophic scars. Materials and Methods: This is a prospective study, where 30 patients who were operated for facial scar revision were divided into two equal groups: The first group was injected with BTA, but the second group was not. They were followed up for three months, and the results were analyzed. Results: Manchester scar scale (MSS) was used to assess the scars. In all the cases, the MSS score reduced after surgical correction, which further reduced after the injection of BTA in the first group of patients. The results are statistically significant (P < 0.01). Conclusion: The BTA plays an important role in the treatment of scars after scar revision surgeries.
