“…Количество рубцов постакне коррелирует с тяжестью предшествующего акне [8], выраженность же рубцов не зависит от тяжести заболевания [8; 11]. Характер рубца зависит от площади и глубины поражения, от индивидуальных особенностей репаративных процессов в коже [12]. По данным J. Tan et al…”

Атрофические рубцы постакне являются часто встречающимся следствием угревой болезни, локализуются на открытых участках кожи, представляют собой стойкий косметический дефект, что обуславливает социальную значимость дерматоза. Терапевтические и хирургические методы лечения применяются в коррекции различных клинических вариантов атрофических рубцов постакне. Выбор эффективной терапевтической стратегии остается сложной задачей для врачей-дерматовенерологов, врачей-косметологов и требует персонифицированного подхода, учитывающего морфологические характеристики рубца. В статье представлены актуальные подходы к клинической классификации и оценке степени тяжести рубцовых деформаций постакне по валидным международным шкалам, а именно международной количественной и качественной классификации рубцов постакне; международной количественной шкале ЕССА; шкале оценки тяжести рубцов постакне Acne Scar Severity Score (SCAR-S). Приведен обзор современных методик коррекции атрофических рубцов постакне, который включает следующие методы: химические пилинги, субцизия, дермабразия, микронидлинг, введение дермальных филлеров и аутологичного жира, PRP-терапия, лазерное и радиоволновое воздействие. Особое внимание уделяется методам лазерной терапии. Авторы заключают, что требуется разработка методологии и стандартизации медицинских процедур, оценка их эффективности и безопасности для достижения предсказуемых результатов коррекции. Ключевые слова: постакне, атрофические рубцы, оценочные шкалы, лечение рубцов.

Background. The choice of an effective method of laser correction of atrophic post-acne scars, suitable for a particular type of scar, remains a difficult task, despite the variety of interventions. Aim. To study the effectiveness of a combination of planar and fractional laser ablation in patients with atrophic post-acne scars, taking into account the predominant type of scar. Material and methods. An open clinical intervention study included 60 patients with IIIV scar severity grade, 36 females and 24 males, with a mean age of 28.874.81 years. The predominance of V-shaped scars was observed in 11 (18.3%) patients, U-shaped in 29 (48.3%), M-shaped in 12 (20.0%), macular in 8 (13.3%) patients. An erbium laser with a wavelength of 2940 nm was used to resurface the edge of the scars, followed by fractional ablation of the affected area. The change in the severity and quantitative index of the severity of post-acne scars after treatment, as well as the results on the international scale of aesthetic improvement, were evaluated. The safety of the method was assessed during a clinical examination on the 7th day after each procedure and 3 months after the last one, any adverse events and complications were recorded. The significance of differences was calculated using the Wilcoxon, MannWhitney, KruskalWallis and the 2 tests. Differences were considered statistically significant at p 0.05. Results. Reduction of scar severity was registered, the quantitative index after treatment decreased from 11.43.25 to 6.23.1 points (p=0.000, Wilcoxon criterion). Regression of quantitative indices was established in patients with U-shaped and macular scars compared with patients with a predominance of M- and V-shaped scars (p 0.05, MannWhitney test). The average effectiveness of treatment on a scale of aesthetic improvement was 2.420.72 points, in 33 (55.0%) people the result corresponded to a significant improvement, in 19 (31.7%) moderately pronounced improvement, a noticeable improvement in appearance compared to baseline was noted in 8 (13.3%) patients (2=23.55, p 0.000). Complications of procedures were not registered. Conclusion. Correction of atrophic scars with an erbium laser, which combines planar and fractional ablation, is effective and safe for various types of atrophic scars; the optimal result is achieved in patients with U-shaped and macular scars.

Introduction. Atrophic scars are common in acne patients. Regardless of their number and size, they are persistent defects and reduce patients' quality of life. With a variety of treatment options, effective scar correction remains a challenge. Laser technology continues to evolve and is considered promising for the treatment of scars.The aim of the study was to investigate the effectiveness of the fractional laser ablation method in patients with atrophic postacne scars using the quantitative postacne scar index.Materials and methods. The study involved 60 patients with ARP of II-IV severity, 35 women and 25 men. The patients underwent fractional ablation of scars with an Erbium laser (2940 nm). To assess the scars before and after treatment, we used the post-acne scar severity index according to the quantitative assessment scale according to G.J. Goodman et al. Goodman et al. (2006). The international scales Patient's Satisfaction Score, Physician's Satisfaction Score, and Definitive Graduated Score were used to assess physician and patient satisfaction with the results of the procedures.Results. The quantitative index of postacne scars before treatment ranged from 4.0 to 16.0 points and averaged 10.9±3.56 points; median was 12.0 points (8.0±13.0 points). After fractional laser ablation procedures, improvement of quantitative indexes scores (p<0.05), positive dynamics of the doctor's and patients' evaluation of procedure results were noted; no gender differences were noted.Discussion. Quantitative indices of scar expression reflect the severity of the affected skin areas in patients with postacne. This study confirms the effectiveness of fractional ablation with the Erbium laser in patients with ARP, which is confirmed by a decrease in quantitative scar severity indices. Dynamic growth of PSS, PhSS, DGS indices testifies to high satisfaction of the physician and the patient with the results of treatment and correlates with regression of clinical manifestations in these patients.Conclusion. Despite the limitations and laboriousness of counting quantitative indices of postacne scars, this approach allowed to establish and objectify the clinical efficacy of treatment of patients with ARP by fractionated ablation.
