Surgical facial rejuvenation techniques with thread lifting have gained popularity. To effectively rejuvenate an aging face, it is necessary to perform both soft tissue envelop repositioning and volume restoration procedures. With the trend toward less invasive techniques and long-lasting results with minimal complications, many surgeons have continued changing the techniques.
In the present study, we developed the 4 M (Multi-target, Multi-vector, Multi-layer, Multi-material) thread lift technique for long-lasting results.
A prospective study was conducted on 73 patients who underwent the 4 M thread lifting procedure between January 2016 and February 2018. To evaluate the surgical outcomes objectively, two plastic surgeons compared photographs using a 5-point Global Aesthetic Improvement Scale (GAIS) at 1, 3, 6, 12, 18, and 24 months of follow-up.
Based on the GAIS objective assessment, in most patients (85%) experienced better than 3 score ("improved") changes. Approximately 42.5% of the patients experienced better than 4 score ("much improved") changes. The mean GAIS grade improved significantly (p < 0.005) without decline throughout a period of 12 months. No serious adverse complication was observed except one patient, who experienced skin irregularities and dimpling for up to 9 months after the procedure.
This 4 M thread lifting is the multiple layer lifting and rejuvenation using different materials in addition to the multiple targets. Using the concepts of structural rejuvenation, the 4 M thread lifting technique presented modest to significant improvement, maintaining good results at 12 months after procedure.

带线提升的面部年轻化手术技术已受到欢迎。为有效改善衰老面容，有必要同时进行软组织包膜复位和容量恢复手术。随着技术朝着侵入性更小、效果持久且并发症最少的趋势发展，许多外科医生不断改进技术。
在本研究中，我们开发了4M（多靶点、多向量、多层、多材料）带线提升技术以获得持久效果。
对2016年1月至2018年2月间接受4M带线提升手术的73例患者进行了一项前瞻性研究。为客观评估手术效果，两名整形外科医生在术后1、3、6、12、18和24个月时使用5分全球美容改善量表（GAIS）对比照片。
基于GAIS客观评估，大多数患者（85%）的变化优于3分（“改善”）。约42.5%的患者变化优于4分（“明显改善”）。GAIS平均评分在12个月内显著改善（p < 0.005）且未下降。除1例患者在术后长达9个月出现皮肤不平整和酒窝状外，未观察到严重不良并发症。
这种4M带线提升是除多靶点外使用不同材料的多层提升和年轻化技术。运用结构年轻化的概念，4M带线提升技术呈现出轻度到显著的改善，术后12个月仍保持良好效果。
