Curative effect of double wavelength non-stripping lattice array laser "water enhancement method" in the treatment of facial sunken scar / 中国基层医药

ABSTRACT

Objective To evaluate the efficacy of dual-wavelength non-stripping dot array laser " water enhancement" in the treatment of facial sunken scar.Methods From June 2017 to February 2018,fifty patients with facial sunken scar were randomly divided into observation group and control group according to the digital table,with 25 cases in each group.The observation group was treated by lidocaine injection combined with dual-wavelength non-stripping lattice laser,while the control group was treated with double-wavelength non-stripping dot array laser. The clinical therapeutic effects of the two groups were compared and analyzed.Results The cure rate of the observa-tion group was 60.00% (15/25),which was significantly higher than that of the control group[36.00% (9/25)], and the difference between the two groups was statistically significant (χ2 =32.524,P<0.05).Conclusion Water assisted 1540 nm lattice laser therapy for facial sunken scar after acne has obviously better effect,safety and less adverse reactions.And it is the most suitable treatment for patients with facial sunken scar after acne in Asia.
