ABSTRACT
Objective:To determine the clinical effect of sequential therapy by local injection of triamcinolone acetonide and lattice CO 2laser for hypertrophic scar. Methods:A total of 80 hypertrophic scar patients, including 45 male and 35 female, in our clinic were randomly divided into test ( n=40) and control ( n=40) groups from March 2019 to May 2020. Patients aged from 18-42 years with average age 28.1. Patients in test groups were treated with triamcinolone acetonide and lattice CO 2laser sequentially. After final treatments, third-party blind evaluation, Vancouver scar scale, visual analog scale and dermatology life quality index were performed. Results:Test group acquired more satisfied result in third-party blind evaluation (82.5% vs. 52.5%, χ2=8.216, P<0.05). Vancouver scar scale, visual analog scale and dermatology life quality index were not significantly different before treatment for both groups while test group acquired better improvement after treatment ( P<0.05). Conclusions:Sequential therapy by local injection of triamcinolone acetonide and lattice CO 2laser is effective for hypertrophic scar and worths wide application in the clinic.
