Abstract

INTRODUCTION: Scar formation is a natural part of the healing process that occurs when the skin repairs wounds caused by burns, trauma, surgery or disease. The appearance of scars often leads to adverse psychological effects, loss of self-esteem and the associated stigmatism and diminished quality of life. Silicones are emerging as the standard treatment for prevention of a wide range of scars. The present study evaluated the safety and efficacy of an advanced formula topical silicone gel for prevention of post-operative hypertrophic and keloid scars.

METHODS: An open-label prospective trial was conducted. Patients who had undergone prior surgery (10 days-3 weeks) and having recent post-surgical scars were enrolled. Patients were asked to apply the gel twice daily to the affected areas for 3 months. Pigmentation, vascularity, pliability, height of scar and pain and pruritus in the scar were assessed. Photographs of scars were taken before commencement of treatment and at follow-up visits.

RESULTS: A total of 36 patients were enrolled. At baseline, height of the scar was 2-5 mm in 57.6 % (19/33) of the subjects which was reduced in subsequent visits (P < 0.05). Hyperpigmentation (score 3) was present in 91% (30/33) of patients at baseline and was reduced to normal (score 0) after 2 months of treatment in 40% (6/14) of patients (P = 0.0313). Vascularity (54.6%, 18/33) at baseline was also reduced over the 3 months period (P = 0.0313) A significant decrease (30%, 3/10) (P = 0.0313) in pliability was seen after 3 months of treatment from the baseline (57.6%, 19/33). Only two patients reported pruritus and pain at the baseline visit; one patient reported improvement after treatment. Itching was reported as an adverse drug reaction in two patients.

CONCLUSION: These preliminary findings suggest that advanced formula silicone gel is safe and effective in the prevention of hypertrophic and keloid scars; however, larger, controlled studies are warranted.
