ABSTRACT
Background@#Recent reports have shown that intralesional botulinum toxin type-A (BTX-A) works on scar cosmesis. @*Objective@#To evaluate the clinical efficacy of combination treatment of laser and BTX-A injection and compare the effects of conventional intralesional injection and intra- and perilesional BTX-A injection on fibrotic thyroidectomy scars. @*Methods@#Patients with fibrotic thyroidectomy scars showing insufficient responses to previous ablative fractional laser (AFL) treatment were enrolled. Combination treatment with AFL and BTX-A injection was performed. Patients who received intra/perilesional BTX-A injections were classified into group A. Group B was patients in whom the injection was performed only intralesionally. The improvement was assessed based on the Vancouver Scar Scale (VSS). @*Results@#A total of 24 patients was included. Statistically significant improvement in pliability and total VSS score after the combination treatment were observed in overall patient group.Subgroup analysis demonstrated that pliability, height, and total VSS improved significantly in group A. In group B, only pliability significantly improved. @*Conclusion@#BTX-A injection combined with AFL can provide better relief for the previously treated fibrotic thyroidectomy scars. Injection of BTX-A not only into the scar itself, but also into perilesional muscles that can exert tension on the scar site may provide additional benefit in flattening scar height.
