Objective: To examine the application of silicone gel sheets on linear scars due to surgical procedures.
Method: Ten individuals, with scars less than 1 year old, participated in the study. The Participant and Observer Scar Assessment Scale (POSAS) was used to evaluate scars on seven characteristics rated by visual analogue scales (VAS). Participants applied silicone gel sheets to half of their scar for 6 months, and every 2 weeks POSAS data forms were completed. Linear mixed-effects analysis of variances (ANOVA) were used to determine if significant differences occurred between groups (treated and untreated scar sides) across the 6 months of data collection. To see if differences were found from the initial evaluation to final visit, Mann-Whitney U tests analysed between-group changes (treated and untreated scar sides), while Wilcoxon signed ranks tests compared within-group changes (evaluation of each scar side over time).
