Silicone sheet is often used for preventing cleft lip scar postoperatively with concerns of ingestion, application site irritation and short application time. Silicone gel has daylong application duration with better safety. Previous study suggested no difference between forms of silicone in treating cleft lip scarring without controlling potential confounders. We aimed to evaluate the effectiveness of silicone gel versus sheet in a different model, controlling surgical gap, side and patient effects.
