The Study group consisted of another 33 consecutive age-matched patients with unilateral cleft lip, whose postoperative scar care was exactly the same except the silicone sheet was replaced with silicone gel (Dermatix Ultra, Menarini, Singapore), which was applied twice per day. The parents (or caregivers) were instructed to apply silicone gel (the amount being similar in size to a grain of rice) along the upper lip scar from the nostril base to the vermillion, avoiding the wet mucosa.
