Abstract:

Objective To examine the effectiveness of a 1 565 nm non-ablative fractional laser combined with silicone gel in the early repair of scarring following head and face emergency trauma. Methods Randomly selecting 80 cases of early scar intervention patients who had experienced head and face emergency trauma at our hospital from September 2021 to December 2022 as research objects， we divided them into two groups and administered silicone gel application， as well as 1 565 nm Non-ablative fractional laser + silicone gel treatment. Each patient received 3 treatments with a 1-month interval between each treatment. Patients in two groups， each with 40 participants， were evaluated with the Patient Assessment Scale （PSAS）， Observer Assessment Scale （OSAS）， and the new Vancouver Scar Scale （VSS） prior to and two weeks after the last treatment. Results The results were documented in terms of patient satisfaction and adverse reactions during the treatment. We discovered that the PSAS， OSAS and VSS scores of the two groups of patients were lower post-treatment （P < 0.05） than before （P < 0.05）. The control group score was also lower than the control group （P < 0.05）. The control group satisfaction was 62.50%， while the observation group was 87.50%. The observation group was comprised of 2 individuals with pigmentation and 1 with pain， while the remainder were healthy. These two groups had distinct side effects. Conclusion It is found that both silicone gel and 1 565 nm non-ablative fractional laser can improve the scars of head and face emergency trauma patients， and the improvement effect of 1 565 nm non-ablative laser is affirmed， and the side effects are relatively small.
