Background: Subcision is a procedure that has been reported to be beneficial in treatment of acne scars.
Objective: This stady aims to assess the efficacy of subcision in the treatment of rolling acne scars and evaluate a novel subdermal filler 'absorbable plain catgut suture' with subcision.
Methods: Twenty-two patients with rolling acne scars underwent subcision, 20 of whom completed treatment and follow-up period. One side of the face underwent subcision and another side subcision with subdermal implant. The patients and investigators' assessment of improvement were both recorded.
Results: Subcision showed mild improvement in about 60% of patient and moderate improvement in about 40% of them. The rate of response showed no significant difference with the use of subdermal implant. The side-effects of local oedema, bruising and infection were all transient.
Conclusions: Subcision seems to be a safe method to correct the rolling acne scars with long-term improvement. However, the subdermal implant led to no significant superior results.
