A subset of facelift patients have premature redevelopment of skin laxity in the lower face and neck. Many patients seek alternatives to revision facelifts to avoid high risks and costs. Radiofrequency-assisted lipolysis (RFAL) with Radiofrequency (RF) microneedling may be alternative minimally invasive options.
OBJECTIVE/AIM: To evaluate the efficacy of radiofrequency energy devices for treatment of premature jowl and neck skin laxity following facialplasty.
This is a single-center, prospective study of patients seeking treatment for jowl and neck skin laxity 1-5 years following facialplasty. Treatment was performed with the InMode radiofrequency AccuTite and Morpheus8 systems. Study duration was 12 months with 6 months of follow-up. Endpoints included improvement in skin tightening assessed by blinded investigators, and investigator and subject assessment of skin appearance. Subjects also rated satisfaction with treatment and pain levels.
The study protocol was completed by nine patients. Based on investigator evaluations, 33% had marked improvement at 3 months, which increased to 55% at 6-month postprocedure. Patient-reported improvement was "markedly improved" in 67%, "moderate improvement" in 11%, and "slight improvement" in 22% at 3 months. Overall patient satisfaction was rated as "very satisfied" by 33% and "satisfied" by 67% at 3 months. There were no adverse events reported.
The results of this study provide supporting evidence that RFAL technology can provide a safe, minimally invasive, and effective treatment for skin laxity in the jowls and neck in patients who desire further correction after undergoing primary facelift.
一部分接受面部提升手术的患者在面部下部和颈部过早出现皮肤松弛。许多患者寻求替代方案以避免进行修复性面部提升手术带来的高风险和高成本。采用射频微针的射频辅助脂肪分解术（RFAL）可能是替代性的微创选择。
评估射频能量设备治疗面部整形术后过早出现的下颌赘肉和颈部皮肤松弛的疗效。
这是一项单中心前瞻性研究，研究对象为面部整形术后1至5年寻求治疗下颌赘肉和颈部皮肤松弛的患者。使用InMode射频AccuTite和Morpheus8系统进行治疗。研究持续时间为12个月，随访6个月。终点指标包括由盲法研究者评估的皮肤紧致度改善情况，以及研究者和受试者对皮肤外观的评估。受试者还对治疗满意度和疼痛程度进行评分。
9名患者完成了研究方案。根据研究者评估，33%的患者在术后3个月有显著改善，术后6个月这一比例增至55%。在术后3个月，患者报告的改善情况为“显著改善”占67%，“中度改善”占11%，“轻微改善”占22%。总体患者满意度在术后3个月时，33%的患者评为“非常满意”，67%的患者评为“满意”。未报告不良事件。
本研究结果提供了支持性证据，表明RFAL技术可为初次面部提升术后希望进一步矫正的患者的下颌和颈部皮肤松弛提供一种安全、微创且有效的治疗方法。
