Abstract:
Objective:To study the effectiveness and safety of combined intraoral and cutaneous using of long pulsed 1064 nm Nd∶YAG and 2940 nm Er∶YAG lasers in facial rejuvenation.Methods:Twenty-one female patients with different grades of nasolabial fold were treated with 6 sessions of the combination lasers therapy once a month. Standardized photographs of VISIA were taken before and after treatment to record any changes of facial contour and nasolabial folds. The efficacy assessment was judged by two non-group experienced dermatologists using modified Fitzpatrick Wrinkle Scale (MFWS), based on the VISIA photos at base line, twelve-week and six-month after treatment. Self-scoring of 5-level satisfaction from patients was also collected and analyzed. Any side effects and complications were recorded.Results:At 12 weeks, mild and moderate nasolabial folds were improved notably, the mean value of MFWS decreased from 1.59 to 0.90, whereas severe nasolabial folds had no remarkable improvement. Six-month after treatment, 18 patients had notable improved, among them: five out of 7 mild cases, 9 out of 10 moderate cases and 2 out of 4 severe cases, and the mean value of MFWS significantly decreased to 0.57 ( P<0.001). The general satisfactory rate of self-scoring was 86%. Two patients had tolerable light burning pain during treatment and two patients got temporary pigmentation that vanished in three months. There were no other adverse reactions and complications. Conclusion:Combined intraoral and cutaneous using oflong pulse 1064 nm Nd∶YAG laser and 2940 nm Er∶YAG laser is a safe and effective therapy for facial rejuvenation.
