Abstract

Objective: To evaluate the initial effectiveness of keloid scars treatment with CO2 laser and intralesional Botulinum toxin type A (Botox A) injection. Subject and method: Descriptive study of a clinical intervention uncontrolled group, comparison on 22 keloid patients treated with CO2 laser combined with intralesional botox A injection. Result: After 3 times of treatment with one month interval, the clinical changes in Vancouver Scar Scale (VSS) score were as follows: At the time of
non-injection (T0), pigment score: 2 ± 0, vascular score: 2.68 ± 0.477; hardness point: 3.05 ± 0.844; thickness score: 2.18 ± 0.501. At the end of the treatment course (T3), the corresponding results were 1.41 ± 0.854, 1.73 ± 6.13, 1.73 ± 0.613, 1.41 ± 0.80 (p<0.05). Overall results, at the time of not injection (T0) and after 3 months of treatment (T3) according to VSS were 9.91 ± 1.411 and 6.27 ± 2.292 (p<0.05), respectively. Most of the patients were satisfied (36.4%) and very satisfied (27.3%) when they were intervened by this method. Conclusion: Keloid scars treatment with CO2 laser and intralesional Botox A injection initially showed positive results, should be an efective solution for keloid treatment.
