Facial contouring procedures are increasingly sought to address aesthetic concerns such as submental fat accumulation and lack of jawline definition. Cryolipolysis and hyaluronic acid (HA) injection have emerged as promising modalities for lower face contouring, targeting fat reduction and jawline enhancement, respectively.
This study aims to assess the efficacy and safety of a combined treatment approach involving cryolipolysis followed by HA injection for addressing lower face contour concerns. Specifically, the study seeks to evaluate outcomes associated with this comprehensive treatment modality in the lower face region.
A retrospective analysis was conducted on four females and one male who underwent cryolipolysis treatment for double chin reduction, followed by HA injection for jawline contouring. Pre- and post-treatment assessments, including digital photographs and standardized measurements, were performed to evaluate changes in lower face contouring. Objective evaluation of treatment outcomes was facilitated using digital photographs and standardized measurements, including 3-D images captured using the VECTRA system. Post-treatment assessments were conducted at 4-week intervals to monitor progress, with participant satisfaction assessed using the Global Aesthetic Improvement Scale (GAIS) at the end of six months after filler treatment.
Findings from this pilot study demonstrate significant improvement in lower face contouring resulting from the combined treatment of cryolipolysis and HA injection. Post-treatment improvements included reduced submental fullness, enhanced definition in the jawline and improved chin projection. The cervicomental angle, measured using VECTRA, demonstrated a reduction post-treatment in all subjects. After Cryolipolysis only, the mean change in cervicomental angle was -4.94°, with a p-value of 0.0635. After both cryolipolysis and fillers, the mean change in cervicomental angle was -9.34°, and the p-value was 0.0244, indicating a statistically significant reduction. Subjective reports from participants, using GAIS, indicated high satisfaction with treatment outcomes.
These results indicate that while cryolipolysis alone shows a trend toward improvement, the addition of hyaluronic acid fillers provides a statistically significant enhancement in cervicomental angle and overall lower face contouring. Hence, integrating cryolipolysis and HA injections offers a comprehensive solution for addressing lower face contour concerns, providing synergistic benefits for both modalities.
面部轮廓整形手术越来越多地被用于解决诸如颏下脂肪堆积和下颌轮廓不清晰等美学问题。冷冻溶脂和透明质酸（HA）注射已成为下颌面部轮廓整形的有前景的方法，分别针对脂肪减少和下颌轮廓增强。
本研究旨在评估先进行冷冻溶脂再进行HA注射的联合治疗方法解决下颌面部轮廓问题的有效性和安全性。具体而言，该研究旨在评估这种综合治疗方式在下颌面部区域的效果。
对4名女性和1名男性进行回顾性分析，他们先接受冷冻溶脂治疗以减少双下巴，然后进行HA注射以塑造下颌轮廓。治疗前后进行评估，包括数码照片和标准化测量，以评估下颌面部轮廓的变化。使用数码照片和标准化测量（包括使用VECTRA系统拍摄的3D图像）对治疗效果进行客观评估。治疗后每隔4周进行一次评估以监测进展，填充治疗6个月后使用全球美学改善量表（GAIS）评估参与者的满意度。
这项初步研究的结果表明，冷冻溶脂和HA注射联合治疗使下颌面部轮廓有显著改善。治疗后的改善包括颏下饱满度降低、下颌轮廓清晰度增强和下巴突出度改善。使用VECTRA测量的颈颏角在所有受试者治疗后均减小。仅进行冷冻溶脂后，颈颏角的平均变化为-4.94°，p值为0.0635。冷冻溶脂和填充剂治疗后，颈颏角的平均变化为-9.34°，p值为0.0244，表明有统计学意义的减小。参与者使用GAIS的主观报告表明对治疗效果高度满意。
这些结果表明，虽然单独的冷冻溶脂显示出改善趋势，但添加透明质酸填充剂在颈颏角和整体下颌面部轮廓方面有统计学意义的增强。因此，将冷冻溶脂和HA注射相结合为解决下颌面部轮廓问题提供了一个全面的解决方案，两种方法具有协同效益。
