Abstract

Traumatic scars negatively impact the patient's quality of life. Fractional 1064 nm Nd: YAG picosecond laser improves scars. However, the effect varies among individuals. This study aimed to evaluate the treatment of traumatic scars with fractional 1064 nm Nd: YAG picosecond lasers and the factors associated with its prognostication. We conducted a retrospective study with 161 patients with traumatic scars. All scars were treated using fractional 1064 nm Nd: YAG picosecond lasers. Efficacy was determined based on blinded visual evaluation using the Manchester Scar Scale (MSS) and 5-point Global Assessment Scale (GAS). The mean MSS values before and after treatments was 17.4 ± 2.7 and 13.6 ± 2.6 (P < 0.001), respectively. Color, radiance, contour, and distortion of the traumatic scars improved. (all P < 0.001). The course, location, and height of the scars, and the number of treatments and energy densities, were related to treatment responses (P < 0.05). Fractional 1064 nm Nd: YAG picosecond laser is effective for treating traumatic scars. Clinicians can predict the prognosis using multiple factors.

分数1064 nm Nd: YAG皮秒激光治疗创伤性疤痕的回顾性研究。

创伤性疤痕会对患者的生活质量产生负面影响。分数1064 nm Nd: YAG皮秒激光改善疤痕。然而，影响因人而异。本研究旨在评价分数阶1064 nm Nd: YAG皮秒激光治疗创伤性疤痕的效果及其预后的相关因素。我们对161例创伤性瘢痕患者进行了回顾性研究。所有疤痕均采用分数1064 nm Nd: YAG皮秒激光治疗。采用曼彻斯特疤痕量表（MSS）和5分全球评估量表（GAS）进行盲法视觉评价，确定疗效。治疗前后平均MSS分别为17.4±2.7和13.6±2.6 （P < 0.05）

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.
