Facial rejuvenation with autologous fat has the advantage of replacing or augmenting tissue with like tissue. The results of injected fat are unpredictable because of cellular trauma and other factors. Excised whole or en bloc fat grafting has been shown experimentally to have a greater percentage of adipocyte survival when compared with blunt cannula delivery techniques. En bloc grafting, however, requires an incision for the harvesting and placement of the fat graft with visible scars. A novel, less traumatic cylinder core fat harvest and delivery technique for facial augmentation with minimal incisional access is reported here.
Twenty-six facial augmentation procedures were performed involving the malar area, buccal area, lips, nasolabial folds, and mental region. Fat transfer volume ranged between 1 and 4 cc per site. In this report, 16 patients' results were documented 6 to 16 months postoperatively (mean follow-up time, 9.5 months) with a postoperative questionnaire and photographs.
Social recovery for patients was short, with a recovery time of 2 to 20 days (mean, 10.91 days). There were no procedure-related complications at the fat harvest or recipient graft sites. The need for overcorrection was minimal. Graft maintenance during the average follow-up at 9.5 months appeared excellent and without appreciable volume loss. The mean patient satisfaction score was 7.64 +/- 2.97 on a scale of 0 to 10.
The authors' preliminary results have demonstrated that this technique is effective and highly predictable. The surgical time was short, and patient recovery time has been significantly reduced compared with recovery time after other fat injection techniques.
自体脂肪面部年轻化具有用相似组织替代或增加组织的优势。由于细胞创伤和其他因素,注射脂肪的效果难以预测。与钝性套管注射技术相比,实验表明切除整块脂肪移植的脂肪细胞存活率更高。然而,整块移植需要切口来获取和放置脂肪移植体,会留下可见疤痕。本文报道了一种新型的、创伤较小的圆柱状核心脂肪获取和移植技术,用于面部填充,切口最小。
对26例面部填充手术进行了研究,涉及颧部、颊部、唇部、鼻唇沟和颏部。每个部位的脂肪转移量在1至4立方厘米之间。在本报告中,通过术后问卷调查和照片记录了16例患者术后6至16个月(平均随访时间9.5个月)的结果。
患者的社交恢复时间短,为2至20天(平均10.91天)。在脂肪获取或移植接受部位没有与手术相关的并发症。过度矫正的需求最小。在平均9.5个月的随访期间,移植维持情况良好,没有明显的体积损失。患者满意度平均评分为7.64±2.97(满分0至10分)。
作者的初步结果表明,该技术有效且高度可预测。手术时间短,与其他脂肪注射技术相比,患者恢复时间显著缩短。
