Abstract:
Objective:To investigate the clinical effect of minimally invasive scar release combined with autologous microfat graft in the treatment of facial depressed scar.Methods:From September 2015 to May 2019, a total of 11 patients who had facial depressed scar were treated with minimally invasive scar release combined with autologous microfat graft in Huaihe Hospital of Henan University. Needle scar separator or 10 ml syringe needle was inserted under skin to release scar adhesion thoroughly. Microfat was harvested from the abdomen, which was separated and purified, and then evenly transplanted into the stripped space (0.5 cm wider than the edge of scar) under the scar with a 1 ml syringe. The severity of scar was evaluated pre-operation, 3-month post-operation and 6-month post-operation, using Vancouver Scar Scale score and Stony Brook Scar Evaluation Scale score to evaluate the efficacy. Using Visual Analogue Scale score to evaluate patient satisfaction. Analyses were performed using SPSS Statistics 25.0, and measurement data were expressed as Mean±SD if they conformed to normality and homogeneity of variance. One-way ANOVA was used for multi-time point data, and the Bonferroni test was performed for pairwise comparison. P<0.05 was considered a statistically significant difference. Results:The depression of scars disappeared immediately after treatment. 6 months after treatment, the surface of the scars was flat, the color and elasticity were close to adjacent normal skin, and the texture of the scars was soft. All patients were followed up for 6 months without recurrence, and 11 patients were satisfied. In Vancouver Scar Scale score, the pre-operation score was 7.27±1.10, the 3-month post-operation score was 2.64±0.81 and the 6-month post-operation score was 0.91±0.54, showing a significant difference ( F=467.98, P<0.001). Pairwise comparison result show that comparing the pre-operation score with 3 or 6 months post-operation score, showing a significant difference ( P<0.001). The comparison between 3 and 6 months post-operation score also showing a significant difference ( P<0.001). In Stony Brook Scar Evaluation Scale score, the pre-operation score was (2.00±0.89), the 3-month post-operation score was 4.45±0.69 and the 6-month post-operation score was 4.45±0.69, showing a significant difference ( F=67.00, P<0.001). Pairwise comparison result show that comparing pre-operation score with 3 or 6 months post-operation score, showing a significant difference ( P<0.001). The comparison between 3 and 6 months post-operation score also showing a significant difference ( P=0.006). The 6-month post-operation Visual Analogue Scale score was 95.0±6.74. Conclusions:Minimally invasive scar release combined with autologous microfat graft in the treatment of facial depressed scar can avoid the post-surgery scar formation and adhesion, and improve the color and texture of the facial hypertrophic scar. This method can be carried out under local anesthesia, with simple procedure and exact effect.
