Clinical evaluation of silicone gel in the treatment of cleft lip scars.

ABSTRACT: Upper lip scars are at risk of hypertrophy. Our center therefore uses microporous tape and silicone sheeting for postoperative scar care following cleft lip repair. However, some babies have previously ingested their silicone sheeting, which has the potential for respiratory compromise or gastrointestinal obstruction. Self-dry silicone gel is reportedly also effective for preventing hypertrophic scars. Hence, we sought to test whether silicone gel, which cannot be ingested whole, might be non-inferior to silicone sheeting for controlling against upper lip scar hypertrophy. This was a mixed prospective and retrospective case-controlled clinical trial involving patients undergoing unilateral cleft lip repair, 29 of whom received standard postoperative silicone sheeting (control group) and another 33 age-matched consecutive patients who received self-dry silicone instead. The Vancouver scar scale, visual analogue scale and photographically assessed scar width assessments were the same in both groups at six months after surgery. In conclusion, silicone gel appears to be non-inferior to silicone sheeting for postoperative care of upper lip scars as judged by scar quality at six months, but silicone sheeting has the safety disadvantage that it can be swallowed whole by babies. It is thus recommended that silicone gel be used for upper lip scar management in babies.

Project description:IntroductionScar 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.MethodsAn 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.ResultsA 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.ConclusionThese 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.
