In Asian populations, an oval face shape with a slimmer lower face is considered favorable. Botulinum toxin type A (BoNT-A) treatment of the lower face for aesthetic purposes is widely performed in Asia, although it is not officially approved for this indication in any country. In this review, the authors highlight recent research describing injection techniques, mechanism of action, clinical efficacy, and key learning points to safely treat benign masseter muscle prominence (MMP) in Asian populations using BoNT-A. To support the existing literature, clinical examples are provided that demonstrate individualized treatment plans for patients with asymmetric vs symmetric MMP and an observed complication after treatment. This review provides insights for optimizing clinical outcomes and for designing future studies investigating the safety and efficacy of BoNT-A for treating MMP.
在亚洲人群中，椭圆形脸且下脸部较窄被认为是美观的。出于美学目的，A型肉毒毒素（BoNT-A）在下脸部的治疗在亚洲广泛开展，尽管在任何国家它都未被官方批准用于这一适应症。在本综述中，作者重点介绍了近期的研究，这些研究描述了使用BoNT-A安全治疗亚洲人群良性咬肌肥大（MMP）的注射技术、作用机制、临床疗效及关键要点。为支持现有文献，文中提供了临床实例，展示了针对不对称与对称MMP患者的个体化治疗方案以及治疗后观察到的一种并发症。本综述为优化临床疗效以及设计未来研究以探究BoNT-A治疗MMP的安全性和有效性提供了见解。
