Purpose: to assess the effects of combined application of high-level laser photocoagulation and simultaneous cryodestruction at pathological scars on the skin.Material and methods. Two groups included patients of both genders aged 18 and older. Patients from the fi rst (main) group (n = 60) had simultaneous high-level laser irradiation and cryodestruction on scar tissue; patients from the second (control) group (n = 30) were treated separately with laser irradiation and cryodestruction. For laser irradiation, laser devise CO2-laser AKHIL with wavelength 10.6 μm, pulsed frequency 10–20 Hz and power 5–15 W was used. For cryodestruction, apparatus “KRIO-RM-01” was used: tip cooling speed of 220 °C/min, the temperature of 180 °C on the tip working part, exposure time – 15–20 sec. The treated patients had hypertrophic and keloid scars. Etiologically, scars were of post-traumatic, postoperative, post-eruptive types. Evaluation criteria were histological examination of biopsy material with eosinhematoxylin, patients’ quality of life, examination of scar zone.Results. The obtained results demonstrate that the combined application of two physical factors (laser + cryo) at scar tissue increases satisfactory outcomes in patients with hypertrophic scars by 75 % and by 53.4 % in the control group. Relapses were seen in both groups: 25 % in the main group and 46 % in the control group. Morphologically, one can see positive changes in degradation of rough fi brous tissue.Conclusion. A combined application of high-intensity laser photocoagulation and simultaneous cryodestruction has been proven to be effective in patients with pathological skin scars.

Background: Treatment and prevention of the development of pathological scars (hypertrophic and keloid) is an important issue in modern dermatology and plastic surgery due to a violation of aesthetic perception (aesthetics), and in severe cases, the function of various areas of the human body. The purpose of this systematic review of the literature was to analyze the proposed effective methods for treating scar deformities of the skin. Methods: The systematic review included articles from Google Scholar, Medline, Scopus, Web of Sciences, PubMed. Search keywords terms included: pathological scar, therapy, botulinum toxin, laser, cryodestruction, hyaluronidase, skin scar prevention, new methods of wound treatment, wound and skin scarring, bioengineering surgery. Results: Conducted a preliminary search and reviewed 132 titles and abstracts in this review and 50 full-text articles were selected of high methodological quality. This review concluded the necessity of developing pre-surgical methods for preventing pathological scarring, which could potentially become a universal standard for any plastic and aesthetic surgery intervention. Treatment depends on the clinical and morphological characteristics of athological scars. Conclusion: The current systematic review demonstrated the need to develop presurgical methods for the prevention of pathological scarring, which could in the future become a universal standard for any intervention in plastic surgery, since the issue of treating skin scars is sufficiently covered in the available world literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
