Acne scars are the most common sequele of the inflammatory process of acne and affects almost 95 percent of the patients with acne vulgaris. Hypertrophic scars and keloid scars result from excessive tissue formation; atrophic scars are characterized by loss or damage of tissue, which are further categorized into ice pick, rolling, and boxcar scars. A total of 45 patients underwent four sessions, four weeks apart, of subcision and microneedling and were assessed for scar grading three months after the final treatment session. Overall improvement was seen in 95.6 percent of patients (improvement by at least 1 grade) with slight erythema, edema and pain for 1 to 2 days. The improvement correlated with the patient-reported assessment of improvement in scars; 17.8 percent of patients perceived a 75- to 100-percent improvement in their acne scars, while 24.4 percent of patients perceived an improvement of 50 to 74 percent. The majority of the patients (55.5%) perceived an improvement of 25 to 49 percent in their scars. Rolling and boxcar scars show more improvement compared to ice-pick scars. This combination is well tolerated in Fitzpatrick Skin Types III, IV and V, with no failure rates. We observed a high level of patient satisfaction and minimal downtime.
痤疮瘢痕是痤疮炎症过程最常见的后遗症，几乎影响95%的寻常痤疮患者。肥厚性瘢痕和瘢痕疙瘩是由过度的组织形成导致的；萎缩性瘢痕的特征是组织缺失或受损，进一步分为冰锥样瘢痕、滚轮样瘢痕和箱车样瘢痕。共有45例患者接受了间隔四周的四轮皮下分离术和微针治疗，并在最后一次治疗后三个月进行瘢痕分级评估。95.6%的患者有整体改善（改善至少1级），伴有1至2天的轻微红斑、水肿和疼痛。改善情况与患者报告的瘢痕改善评估相关；17.8%的患者认为其痤疮瘢痕改善了75%至100%，而24.4%的患者认为改善了50%至74%。大多数患者（55.5%）认为其瘢痕改善了25%至49%。与冰锥样瘢痕相比，滚轮样瘢痕和箱车样瘢痕改善更明显。这种联合治疗在Fitzpatrick皮肤分型为III、IV和V型的患者中耐受性良好，无失败率。我们观察到患者满意度高，且停工期短。
