Randomized Controlled Trial Clinical TrialHypertrophic sternal scars: silicone gel sheet versus Kenalog injection treatment.
A prospective, randomized trial was designed to compare the standard Kenalog injection of established hypertrophic sternal scars with topical silicone gel sheets (Spenco). Fourteen poststernotomy cardiac patients with symptomatic scars were randomized to treatment in one-half of the scar with Kenalog injection. Simultaneously, the other half of the scar received the silicone gel sheet. ⋯ For the total sample of 14 subjects, 11 preferred the silicone gel, 1 expressed no preference, and 2 preferred the injection. The average time to improvement was 3.9 +/- 0.62 days (gel) versus 6.8 +/- 1.86 days (Kenalog). This study demonstrates that silicone gel sheets provide earlier symptomatic relief and a more aesthetic scar and are the preferred treatment of patients with symptomatic hypertrophic sternal scars.
