Objectives: 1. To treat atrophic/fibrotic scars from causes other than acne with the combination of microcannula subcision and polycaprolactone infiltration. 2. To evaluate the improvement and satisfaction of the patient through interview, clinical analysis and photographic comparison. Introduction: Subincision (SI) as been used to improve the appearance of depressed/atrophic scars1,2. The combination of SI plus filler materials that stimulate neocollagenesis, such as polylactic acid and polymethyl methacrylate has suggested greater efficacy in the results3,4. Polycaprolactone (PCL) is a bioabsorbable polymer widely used in medicine; as well as in the aesthetic industry in rejuvenation treatments with minimal adverse effects and long lasting results with evidence in dermal thickness improve. We found one paper about the use of PCL in acne scars but not from causes other than acne. Materials / method: We present 3 cases, all scars from various causes (one for trauma; and two post aesthetic surgical complication). In all treated cases we perform debridement of fibrosis with 23G microcannula plus infiltration of 0.5 to a maximum of 1 ml of PCL. Photographic evidence was taken before the treatment and at one month in two cases and at 6 months in the last case. Results: We were able to observe improvement in all treated cases. In clinical assessment and photographic comparison we appreciate better texture , greater thickness, and smoother surface in each study case. Conclusion: The use of PCL biopolymer associated with fibrosis debridement by sub-incision with microcannula offers satisfactory results in the medium term in the improvement of atrophic/fibrotic scars.
