Résumé
Objective:To evaluate the clinical efficacy of 1 064 nm/755 nm dual wavelength laser on hair removal.Methods:A total of 60 patients aged 18-52 (30±7) years in our hospital from January 2017 to December 2017 were collected. 1 064 nm and 755 nm laser hair removal was performed at the same symmetrical areas or two different areas in the same patient. We performed 6 sessions of laser treatment at 6-week intervals and the effect was evaluated 6 weeks after the last session.Results:The hair removal efficacy was 96.7% (58 cases) at 1 064 nm, 96.7% (58 cases) at 755 nm laser treatment. There was no significant difference in the effective rate between two wavelengths laser hair removal methods ( P>0.05). The incidence of pigmentation was 1.7% (1 case) at 1 064 nm laser and was 3.3% (2 cases) at 755 nm laser without significant difference ( P>0.05). No hypopigmentation, blister or scar appeared in all patients. The total satisfactory rate was 95.0% (57 cases) at 1 064 nm, 98.3% (59 cases) at 755 nm laser treatment, respectively. Conclusions:1 064 nm/755 nm dual wavelength laser has definite therapeutic effect and safety on hair removal.
Résumé
Objective To explore the clinical efficacy and side effects of Q 532 laser in the treatment of recurrent café-au-lait spots.Methods Collection period was from January 2018 to January 2019.Fifty-five patients with recurrent café-au-lait spots after 2-3 times of Q-switched 755 laser treatment were selected and then treated with Q-switched 532 laser.Treatment was given once every 3-6 months.The appropriate treatment parameters were selected according to the patient's condition.The effects of age,gender,size,morphology and margin of the lesion on the treatment were observed.Results Among the 55 patients treated with Q 532 laser after 2 to 5 treatments,19 cases were cured,13 cases markedly effective,15 cases moderately effective,8 cases invalid with a total effective rate of 85 ％.Conclusions Q 532 laser is an effective and safe treatment for recurrent Café-au-lait spots.
