ABSTRACT

Objective: To compare three treatment strategies for hypertrophic scars: corticosteroid injection, pulse-dyed laser, and Erbium laser.

Study Design: A cross-sectional comparative study

Place and Duration of Study: This study was conducted at the dermatology department of Bakhtawar Amin Trust Teaching Hospital Multan from Jan 2020 to Jan 2021.

Materials and Methods: After passing through the selection criteria, the patients were divided into three groups: corticosteroid, pulse-dyed laser, and erbium such that 20 patients were placed in each group. Patients in all three groups were photographed before and after four weeks of their respective treatments such that the specification of photographs was kept constant. Vancouver Burn Scar scale was used for the evaluation of the treatment outcomes. Moreover, vascularity and height scores were also assessed.

Results: A total of 60 patients were included in the study, 20 in each group. The mean VBS score of patients in the PDL group decreased significantly from 8.7 ± 1.5 to 3.9 ± 1.7, p = 0.001. Similarly, the VBS score of patients in the Erbium group decreased significantly from 9.3 ± 1.3 to 5.2 ± 1.4, p=0.032. However, no significant difference was found in the VBS score of patients in the corticosteroid group (p>0.05). The vascularity score was significantly improved in patients from PDL and erbium groups (p=0.01 and p=0.02, respectively). Similarly, height score was significantly improved in PDL (2.24 vs 1.45, p=0.1) and erbium group (2.26 vs 1.39, p= 0.02) after the treatment.

Conclusion: Both pulse-dyed and erbium laser is significantly more effective than corticosteroid treatment in improving the Vancouver Burn Scar scale, vascularity, and height scores of hypertrophic scars.
