【 摘 要 】

Objective: Stretch marks (striae) can be distressing for many people, and currently available treatments are less than optimal. A previous study showed that the use of a calcium hydroxylapatite (CaHA) filler followed by the topical application of 20% ascorbic acid solution and microneedling significantly improved striae appearance. We sought to evaluate additional improvements in atrophy and color of striae following treatment with microfocused ultrasound with visualization (MFU-V) in subjects who received previous treatments using CaHA, 20% ascorbic acid, and microneedling. Participants: Subjects with remaining skin atrophy (N=20) were treated with MFU-V using transducers with a frequency of 7MHz and 10MHz and a focal depth of 3.0 mm and 1.5 mm, respectively, applied in a cross-hatch pattern. Measurements: Efficacy was based on changes in Manchester Scar Scale scores. Results: At Day 90 post-treatment, the mean (± standard deviation) baseline Manchester Scar Scale score decreased from 9.35 (±1.18) to 6.30 (±1.26) (p<0.001) and the mean Patient Satisfaction Scale score increased from 3.75 (±0.44) to 4.70 (±0.47) (p<0.001). Most subjects (70%) were very satisfied with their results. No adverse events were reported. Conclusion: The combined use of CaHA, 20% ascorbic acid, and microneedling appears to be effective in improving the appearance of striae. Additional esthetic improvements were seen with the application of MFU-V.
