概括

将酸 (HA) 或聚-L-乳酸 (PLLA-SCA) 注射到后部,不会产生显著的面部提升效果. 这项研究发现,这些治疗方法对软组织的移位是最小的,并且没有临床上有意义的美学改善.

科学领域:

审美医学是一种美学医学.
皮肤病学皮肤病学
整形外科手术整形外科手术

背景情况:

在面部提升中后部区域的作用受到辩论.
在这个领域缺乏对注射剂的客观评估.

研究的目的:

量化评估氨酸 (HA) 和聚-L-乳酸 (PLLA-SCA) 在后区域的影响.
评估注射后软组织位移和美学结果.

主要方法:

一个随机的,分脸试验,涉及17名参与者.
在后部注射HA (0.5毫升) 和PLLA-SCA (4.5毫升).
软组织位移的3D立体摄影仪和全球美学改进量表 (GAIS) 的结果.

主要成果:

无论是HA还是PLLA-SCA都导致了最小的,临床上无关紧要的软组织移位.
在治疗之间或随着时间的推移,没有观察到异位的显著差异.
90天和180天没有发现相关的美学改善;没有发生严重的不良事件.

结论:

这是第一个分脸试验,客观地评估面部提升后部区域.
在这个区域注射HA或PLLA-SCA不足以产生临床上有意义的起重效应.
在实践中使用的当前体积在注入后部区域时不会产生显著的提升.

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
