Microfocused ultrasound with visualization (MFU-V) is a well-established treatment modality for skin tightening. There is a paucity of evidence for its use in body treatments, such as the lower abdomen.
To investigate the effectiveness and safety of MFU-V in treating lower abdominal skin and soft-tissue laxity in postpartum women.
The lower abdomen of 20 female patients between 6 and 24 months postpartum are treated with MFU-V using 1.5-, 3.0-, and 4.5-mm transducers. Data are prospectively collected and analyzed at 3 and 6 months using subject-reported and investigator-reported outcome measures. One additional patient underwent planned abdominoplasty 6 weeks after MFU-V treatment with tissue assessed intraoperatively and histologically.
There was a mean improvement of 1.0 and 1.3 grades at 6 months using the investigator-reported and patient-reported skin laxity scale, respectively (p < .001). Patient-reported outcomes and satisfaction survey showed consistent improvement at 6 months. Histological examination of pretreated tissue showed increased total collagen, increased number and thickness of fibrous septae, and no change in fat cells within pretreated tissue compared with the control. No significant adverse events were recorded.
MFU-V is an effective and safe treatment modality for lower abdominal skin laxity in postpartum patients.
微聚焦超声可视化（MFU-V）是一种成熟的皮肤紧致治疗方法。然而，其在腹部治疗（如下腹）中的应用证据有限。
研究 MFU-V 治疗产后女性下腹皮肤和软组织松弛的有效性和安全性。
使用 1.5、3.0 和 4.5mm 换能器对 20 名产后 6 至 24 个月的女性患者的下腹进行 MFU-V 治疗。使用患者报告和研究者报告的结局评估方法，在 3 个月和 6 个月时前瞻性地收集和分析数据。1 名患者在 MFU-V 治疗 6 周后计划行腹成形术，术中评估和组织学评估。
使用研究者报告和患者报告的皮肤松弛量表，6 个月时分别有 1.0 和 1.3 个等级的平均改善（p <.001）。6 个月时患者报告的结局和满意度调查显示持续改善。与对照组相比，预处理组织的组织学检查显示总胶原增加、纤维隔的数量和厚度增加，而预处理组织中的脂肪细胞没有变化。未记录到明显的不良事件。
MFU-V 是治疗产后患者下腹皮肤松弛的有效且安全的治疗方法。
