Abstract
Multiple mode procedures (MMP) of fractional CO2 laser provide higher efficacy and shorter downtime in treating acne scars, compared to traditional fractional CO2 laser therapy. This study aims to evaluate the effectiveness and safety of modified MMP integrated with fractional microneedle radiofrequency (FMR), ultra-pulse CO2 laser and fractional CO2 laser in treating acne scars. A retrospective analysis of 162 acne scar patients treated with MMP or modified MMP was conducted. Acne scars were evaluated using the Echelle d'Evaluation Clinique des Cicatrices d'Acné (ECCA) grading scale, modified Manchester Scar Scale (mMSS), and Global Assessment Scale (GAS). Baseline variables were balanced with propensity score matching (PSM) to improve the comparability of treatment effectiveness and safety between groups. Among 162 patients with facial acne scars, 68 were treated with modified MMP and 94 with traditional MMP. After PSM, both groups had 55 patients with comparable baseline characteristics (P > 0.05). The ECCA score decreased more significantly in the modified MMP group (60%±11%) than in the MMP group (45%±16.6%, P < 0.001). The modified MMP group also had higher mMSS color score (2.6 ± 0.7 vs. 2.1 ± 0.9, P = 0.005), greater reduction in pore size and skin laxity (P < 0.001), shorter postoperative erythema duration (22.2 ± 4.0 vs. 31.3 ± 3.7 days, P < 0.001), but higher pain scores (Visual Analogue Scale, VAS: 6.7 ± 1.6 vs. 3.8 ± 0.8, P < 0.001). Modified MMP is more effective than traditional MMP in treating acne scars, especially for patients with large pores and skin laxity.
期刊介绍:
Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics.
The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
