Objective To observe the effectiveness and safety of narrow-spectrum intense pulsed light (DPL) in the treatment of scar after surgery of primary unilateral cleft lip. Methods From September 2019 to June 2022, 56 children with primary unilateral cleft lip treated by surgery were selected. According to random number table, they were divided into group A and group B respectively, with 28 children in each group. Both groups began to use silicone gel drug to smear the scar on the second day after surgery until 6 months post-operation. Group B also taken three times DPL treatment at 4, 6 and 8 weeks post-operation. The scar was evaluated with Vancouver scar scale (VSS) before DPL treatment, after the last DPL treatment, 4 months after operation, and 6 months after operation. At the final follow-up, satisfaction questionnaire was used to evaluate the satisfaction of parents. The treatment-related adverse events during the DPL treatment pe-riod and within 1 month after the last treatment were recorded. The data was statistically analyzed. Results The difference of VSS scores between the two groups before DPL treatment was no significant (P>0.05). After the last DPL treatment, the VSS score of group B was lower than that of group A, with a statistically significant difference (P<0.05). At 4 months and 6 months post-operation, the VSS score of group B was lower than that of group A, the difference was statistically significant (P<0.05). At the final follow-up, 15 (53.6%) of group A were very satisfied with the efficacy, 10 (35.7%) were satisfied, and 3 (10.7%) were average; 24 (85.7%) of group B were very satisfied with the efficacy, and 4 (14.3%) were satisfied. Two patients in group B had transient pigmentation after treatment. Conclusion DPL can effectively treat the scar after primary unilateral cleft lip surgery, with high patient satisfaction and less adverse events.
