The Role of Chemoimmobilization in Improving the Outcome of Scar Revision Surgery.

Abstract

The major goal of scar revision is to make the scar aesthetically more acceptable. The injection of botulinum toxin type A is known to help in improving the outcomes of scars by reducing the tension across the wound edges and by promoting better wound healing. The aim of this article is to evaluate the efficacy of botulinum toxin injection following scar revision surgeries. A prospective, comparative study involving 20 patients with post-traumatic scars over the face was conducted between July 2018 and July 2019. The patients were divided into two groups: group A underwent scar revision surgery followed by BTX injection on the day of suture removal and group B underwent scar revision surgery alone. The photographic assessment was done at the end of a 1-year follow-up, by three blind investigators based on a pre-designed scale to grade improvement. The average grade of improvement of group A (3.02±1.1) was significantly higher when compared with that of group B (2.1±0.8) (P = 0.001). This study demonstrates that the combination treatment of scar revision with BTX injection is very effective in producing aesthetically better scars.
