Abstract
Purpose: This study was conducted to assess the effect of polarized light on post burn hypertrophic scars. Subjects and Methods: Thirty patients complaining of hypertrophic scars after thermal burn with ages ranged from 20 to 40 years participated in this study. They were divided randomly into two groups equal in number. group A (Study group): Received 10 min. polarized light therapy 3 sessions/week in addition to silicone gel sheet 12 hours/day, medical treatment and routine physical therapy for 2 months. While group B (Control group): Received silicone gel sheet 12 hours/day, medical treatment and routine physical therapy for 2 months. Methods of assessment before and after the study included Vancouver scar scale (VSS) to assess hypertrophic scar characteristics (height, vascularity, pigmentation and pliability) and photographic method for visual assessment of the scars. Results: There was a significant decrease in height, vascularity, pigmentation and pliability scores post treatment compared with that pre treatment in the study group.Comparison between the two groups post treatment revealed that there was a significant decrease in height and pliability scores of the study group compared with that of the control group, while there was no significant difference in vascularity and pigmentation scores between groups. Conclusion: Polarized light therapy is non-invasive, easy to apply and effective for the treatment of post burn hypertrophic scars
