Minimally invasive or noninvasive skin-tightening procedures have become trends in facial and neck rejuvenation. Radiofrequency-assisted liposuction (RFAL) is a new choice for the treatment of skin relaxation that is more effective than noninvasive surgery without surgical incision.
The authors recommend a 2-step method in which radiofrequency is applied after appropriate liposuction is performed. This approach is safer and more effective than traditional RFAL, and the authors detail the safety guidelines, operative techniques, postoperative satisfaction results, and complications.
A total of 227 patients with lower face and neck skin laxity underwent RFAL between April 2012 and June 2019. The following data were collected: age, body mass index, operative duration, volume of fat aspirated, amount of energy delivered, and number and type of complications. Patient satisfaction was surveyed postoperatively and assessed by third-party surgeons at 3 and 6 months.
At 6 months after operation, 78.8% of patients considered the results moderate to excellent, whereas 21.2% of the patients considered the results to be poor or thought there was no change. The photograph evaluation performed by independent plastic surgeons showed moderate to excellent results in 89.1% of patients. There were no major complications that required further medical or surgical intervention.
This 2-step method is a safe and effective improvement in the application of radiofrequency for face and neck skin tightening. Patients can achieve significant contour correction via minimally invasive surgery with a lower risk of side effects.
微创或无创皮肤紧致术已成为面部和颈部年轻化的趋势。射频辅助吸脂术（RFAL）是一种治疗皮肤松弛的新选择，其效果优于无创手术，且无需手术切口。
作者推荐两步法，即在适当吸脂后应用射频。与传统的 RFAL 相比，这种方法更安全、更有效，作者详细介绍了安全指南、手术技术、术后满意度结果和并发症。
2012 年 4 月至 2019 年 6 月，共有 227 例面颈部皮肤松弛的患者接受了 RFAL 治疗。收集了以下数据：年龄、体重指数、手术时间、抽吸脂肪量、能量输送量、并发症的数量和类型。术后对患者进行满意度调查，并由第三方外科医生在 3 个月和 6 个月时进行评估。
术后 6 个月时，78.8%的患者认为效果为中度至极好，而 21.2%的患者认为效果较差或认为没有变化。独立整形外科医生进行的照片评估显示，89.1%的患者效果为中度至极好。没有需要进一步医疗或手术干预的重大并发症。
这种两步法是射频在面部和颈部皮肤紧致中的应用的一种安全有效的改进。患者可以通过微创手术实现显著的轮廓矫正，副作用风险较低。
