Consideration of facial muscle dynamics is underappreciated among clinicians who provide injectable filler treatment. Injectable fillers are customarily used to fill static wrinkles, folds, and localized areas of volume loss, whereas neuromodulators are used to address excessive muscle movement. However, a more comprehensive understanding of the role of muscle function in facial appearance, taking into account biomechanical concepts such as the balance of activity among synergistic and antagonistic muscle groups, is critical to restoring facial appearance to that of a typical youthful individual with facial esthetic treatments. Failure to fully understand the effects of loss of support (due to aging or congenital structural deficiency) on muscle stability and interaction can result in inadequate or inappropriate treatment, producing an unnatural appearance. This article outlines these concepts to provide an innovative framework for an understanding of the role of muscle movement on facial appearance and presents cases that illustrate how modulation of muscle movement with injectable fillers can address structural deficiencies, rebalance abnormal muscle activity, and restore facial appearance.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

考虑到面部肌肉动态在提供注射填充剂治疗的临床医生中被低估，因此，在考虑到协同和拮抗肌肉群之间的活动平衡等生物力学概念的情况下，全面了解肌肉功能对面部外观的作用，对于通过面部美学治疗将面部外观恢复为典型年轻个体的外观至关重要。如果不能充分理解支撑力丧失（由于衰老或先天结构缺陷）对肌肉稳定性和相互作用的影响，可能会导致治疗不足或不当，从而产生不自然的外观。本文概述了这些概念，为理解肌肉运动对面部外观的作用提供了一个创新框架，并介绍了一些病例，这些病例说明了如何通过注射填充剂来调节肌肉运动，以解决结构缺陷、重新平衡异常的肌肉活动，并恢复面部外观。
