MORPHOLOGICAL CHARACTERISTICS AND CAUSES OF ATROPHIC SCAR TREAT WITH SUBCISION AND PLATELET-RICH PLASMA AT THE CAN THO DERMATO-VENEREOLOGY HOSPITAL IN 2021-2023

Abstract

Background: Atrophic scars are the result of natural healing leading to the formation of replacement fibrous tissue. The atrophic scar is a common undesirable complication of acne, chickenpox, herpes, trauma, etc. Although the disease does not cause dangerous complications, due to the location of the lesions on the face, it causes great aesthetic and psychological obstacles, and the patient is less confident in communication, profoundly affecting the patient's quality of life. and labor productivity. The combination of subcision and platelet-rich plasma (PRP) in the treatment of atrophic scars is a new method applied in recent years. The morphological characteristics and causes of them may affect the results of subcision and platelet-rich plasma treatment. Objectives: To describe the clinical characteristics and causes of atrophic scars in patients at Can Tho Dermato-Venereology Hospital from 4/2021 to 6/2023. Materials and methods: A cross-sectional descriptive study was carried out on 30 patients with atrophic scars who were treated with subcision and platelet-rich plasma at Can Tho Dermato-Venereology Hospital in 2021 –2023. Results: the average age of onset of atrophic scars was 21.27 ± 4.085 years old, and the average duration of atrophic scars was 6.33 ± 4.31 years. The majority of patients had acne scars, accounting for 90%; only 6.7% had post-varicella scars; and 3.3% had traumatic scars. 70% with mixed scars, and the common rate of boxscar (83.3%). Scars on the cheek were 100%, and 80% of patients appear to have atrophic scars in multiple locations. Scars color as normal skin accounted for 66.7%. The most atrophic scar patients classified as grade 3 accounted for 66.7%, grade 4 accounted for 23.3%, and at least level 2 accounted for 10%. Conclusions: Facial atrophic scars are mainly the result of acne. Most of them have mixed scars, boxscar are common. Atrophic scars are mainly distributed on the cheeks and in multiple locations. And grade 3 accounts for the majority.
