The capacity to benefit from scar tissue retraction beneath the intact skin has been demonstrated by a number of surgeons working in the superficial fat over the past decade. The efforts to achieve predictable skin retraction have largely overlooked the importance of the mechanism of removal of fat, focusing instead on the depth of the surgical plane and the vacuum pressure utilized. Recent experimental and clinical evidence has pointed out the role of mechanical dislodgment as a key factor in fat removal. A modification of an existing cannula design has been utilized to achieve predictable skin retraction in the face and neck in a series of 75 patients with follow-up from 3 months to 3 years. Facial and cervical flap elevation with this instrument (with or without deep tissue tightening and skin excision) has consistently enhanced results, improving skin tone and facial contours and at the same time diminishing both recovery and operative time. The combination of the technique described and existing techniques such as endoscopic and composite lift approaches may offer enhancement of achievable results.
在过去十年中，许多在浅表脂肪层工作的外科医生已经证明了从完整皮肤下方的瘢痕组织收缩中获益的能力。为实现可预测的皮肤收缩所做的努力在很大程度上忽视了去除脂肪机制的重要性，而是将重点放在手术平面的深度和所使用的真空压力上。最近的实验和临床证据指出，机械性移位是脂肪去除的关键因素。在一系列75例患者中，采用了一种对现有套管设计的改良方法，以在面部和颈部实现可预测的皮肤收缩，随访时间为3个月至3年。使用该器械进行面部和颈部皮瓣提升（无论是否进行深部组织收紧和皮肤切除）均持续改善了效果，改善了肤色和面部轮廓，同时减少了恢复时间和手术时间。所述技术与现有技术（如内镜和复合提升方法）的结合可能会增强可实现的效果。
