Increasing the effectiveness and longevity of a rhytidectomy is a constant pursuit in aesthetic surgery. Contouring of the cervicomental angle and jawline is perhaps the most contentious approach to improving outcomes. Full release of the platysma and the superficial musculoaponeurotic system (SMAS) unit near its inferior border offers a powerful technique to resuspend and bolster the newly surgically restored acute cervicomental angle.
The goal of this study was to demonstrate the effectiveness and longevity of neck recontouring by complete platysmal transection.
A retrospective chart review was performed on all face/lower face/neck lift patients. Operative reports were reviewed to ensure that full release of the platysma-SMAS unit was performed for resuspension. Retrospective photographic analysis was performed to evaluate the objective results of increased cosmesis of the rejuvenated neck and jawline.
Impressive cosmetic results were demonstrated in patients who had full release and resuspension of a plicated platysmas and SMAS unit. These results were objectively appreciated. The enhanced cosmetic appearance was demonstrated to have good longevity and a profound effect on augmenting the acuteness of the cervicomental angle and the cosmetic appearance of the mandibular border.
Release and resuspension of the platysma SMAS unit is an incredibly powerful and long-lasting modality for improving the cervicomental angle and delineation of the mandibular border in facelift patients.

提高除皱术的效果和持久性是美容外科不断追求的目标。改善下颌颈角和下颌轮廓或许是改善手术效果最具争议的方法。在颈阔肌及其下缘附近的表浅肌肉腱膜系统（SMAS）单元进行完全松解，为重新悬吊和支撑新手术修复的急性下颌颈角提供了一种有力技术。
本研究的目的是证明通过完全横断颈阔肌进行颈部轮廓重塑的有效性和持久性。
对所有接受面部/面下部/颈部提升手术的患者进行回顾性病历审查。查阅手术报告以确保对颈阔肌-SMAS单元进行完全松解以进行重新悬吊。进行回顾性照片分析以评估年轻化颈部和下颌轮廓美容效果改善的客观结果。
在颈阔肌和SMAS单元完全松解并重新悬吊的患者中取得了令人印象深刻的美容效果。这些结果得到了客观认可。改善后的美容外观显示出良好的持久性，对增加下颌颈角的锐度和下颌缘的美容外观有深远影响。
颈阔肌SMAS单元的松解和重新悬吊是改善面部提升患者下颌颈角和下颌缘轮廓的一种极其有效且持久的方法。
