The Important Factors Associated with Treatment Response in Laser Treatment of Facial Scars: A Single-Institution Based Retrospective Study

BACKGROUND: There is increased interest in laser treatment of facial scars. OBJECTIVE: To determine the factors associated with treatment response. METHODS: We conducted an institution-based retrospective study by including the patients treated with laser for facial scars from 2012 to 2015. Treatmen...

description BACKGROUND: There is increased interest in laser treatment of facial scars. OBJECTIVE: To determine the factors associated with treatment response. METHODS: We conducted an institution-based retrospective study by including the patients treated with laser for facial scars from 2012 to 2015. Treatment methods were determined with an algorithm according to individual scar characteristics. In each treatment session, either a 595-nm pulsed-dye laser or a non-ablative fractional laser was used, often in combination with a corticosteroid injection. We evaluated treatment responses based on the number of treatment sessions required to reach the treatment endpoint. Data were analyzed using multinomial logistic regression analysis to examine the association between treatment response and various factors of the scar. RESULTS: A total of eighty-four scars were analyzed. The onset of treatment (defined as the period between the injury and treatment initiation), used laser modality, and the location of the scar were all found to be significantly associated with treatment responses. Early implementation was more likely to provide better treatment response. Scars on the perioral area were more likely to be associated with worse treatment response. CONCLUSION: The important factors for the treatment response in facial scars were the location of the scar and the timing of the initiation of treatment. Such information can be used to predict treatment response and tailor the treatment plan to the patient, depending on scar characteristics.
