Optimal Timing of Fractional CO 2 Laser on Cleft Lip Scars: A Single-Blind Randomized Controlled Cohort Study

Laser therapy for treating cleft lip or/and palate scarring-a systematic review and meta-analysis

This review aims to assess the efficacy and safety of laser therapy in managing scars resulting from cleft lip and/or palate (CL/P) repair surgeries, as well as to determine the optimal timing for intervention. A systematic search was conducted across four databases using a predefined search strategy. Studies included were randomized controlled trials, non-randomized studies, and case series focusing on laser therapy for CL/P scars. Data extraction and analysis were performed using Revman Software. A total of two randomized controlled trials, four non-randomized studies, and three case series were included in the analysis. The fractional CO2 laser was the most commonly utilized type of laser. Following laser therapy, there was a significant decrease in Vancouver Scar Scale (VSS) scores by 4.05 (95% CI, 2.10-5.99). Meta-analysis revealed that laser treatment groups exhibited a significantly lower mean VSS score (1.3; 95% CI, 0.02-2.67) compared to control groups. Moreover, initiating laser therapy intervention at one month postoperatively resulted in a significantly lower VSS score compared to initiation at three months postoperatively (difference of 1.70; 95% CI, 1.33-2.08). No severe complications were reported. Laser therapy demonstrates effectiveness and safety in improving CL/P scars, with earlier intervention yielding greater benefits.

Effect of Laser and Energy-based Device Therapies to Minimize Surgical Scar Formation: A Systematic Review and Network Meta-analysis

Utilization of lasers and energy-based devices for surgical scar minimization has been substantially evaluated in placebo-controlled trials. The aim of this study was to compare reported measures of efficacy of lasers and energy-based devices in clinical trials in preventing surgical scar formation in a systematic review and network meta-analyses. Five electronic databases, PubMed, Scopus, Embase, ClinicalTrials.gov, and the Cochrane Library, were searched to retrieve relevant articles. The search was limited to randomized controlled trials that reported on clinical outcomes of surgical scars with treatment initiation no later than 6 months after surgery and a follow-up period of at least 3 months. A total of 18 randomized controlled trials involving 482 participants and 671 postsurgical wounds were included in the network meta-analyses. The results showed that the most efficacious treatments were achieved using low-level laser therapy) (weighted mean difference -3.78; 95% confidence interval (95% CI) -6.32, -1.24) and pulsed dye laser (weighted mean difference -2.46; 95% CI -4.53, -0.38). Nevertheless, low-level laser therapy and pulsed dye laser demonstrated comparable outcomes in surgical scar minimization (weighted mean difference -1.32, 95% CI -3.53, 0.89). The findings of this network meta-analyses suggest that low-level laser therapy and pulsed dye laser are both effective treatments for minimization of scar formation following primary closure of surgical wounds with comparable treatment outcomes.

The Measure of a Scar: Patient Perceptions and Scar Optimization after Skin Cancer Reconstruction

In facial reconstruction after skin cancer resection, management and optimization of postoperative scar is a complex paradigm. Every scar is unique and presents a different challenge-whether due to anatomic, aesthetic, or patient-specific factors. This necessitates a comprehensive evaluation and an understanding of the tools at hand to improve its appearance. How a scar looks is meaningful to patients, and the facial plastic and reconstructive surgeon is tasked with its optimization. Clear documentation of a scar is critical to assess and determine optimal care. Scar scales such as the Vancouver Scar Scale, the Manchester Scar Scale, the Patient and Observer Assessment Scale, the Scar Cosmesis Assessment and Rating "SCAR" Scale, and FACE-Q, among others, are reviewed here in the context of evaluating postoperative or traumatic scar. Measurement tools objectively describe a scar and may also incorporate the patient's assessment of their own scar. In addition to physical exam, these scales quantify scars that are symptomatic or visually unpleasant and would be best served by adjuvant treatment. The current literature regarding the role of postoperative laser treatment is also reviewed. While lasers are an excellent tool to assist in blending of scar and decreasing pigmentation, studies have failed to evaluate laser in a consistent, standardized way that allows for quantifiable and predictable improvement. Regardless, patients may derive benefit from laser treatment given the finding of subjective improvement in their own perception of scar, even when there is not a significant change to the clinician's eye. This article also discusses recent eye fixation studies which demonstrate the importance of careful repair of large and central defects of the face, and that patients value the quality of the reconstruction.
