Botulinum toxin type A (BTX-A) has been used for years with excellent results for upper facial cosmetic applications. Because of this success, the use of BOX-A for facial aesthetics has expanded to the lower facial and neck regions. BTX-A, especially when used in combination with fillers, has generally proven to be safe and efficacious in these areas. For optimal results, however, several issues must be taken into considerations, including dosing differences versus upper facial applications, the specific type of botulinum toxin used and the importance of precise placement and injection technique. In this article, the authors present their experience with BTX-A in the lower face and neck, and compare and contrast their current practices with those reported by others.
A型肉毒杆菌毒素（BTX-A）多年来一直用于上半面部的美容应用，效果极佳。鉴于此成功经验，BTX-A在面部美学中的应用已扩展至下半面部和颈部区域。BTX-A，尤其是与填充剂联合使用时，在这些区域总体上已被证明是安全有效的。然而，为了达到最佳效果，必须考虑几个问题，包括与上半面部应用相比的剂量差异、所使用的肉毒杆菌毒素的具体类型以及精确注射位置和注射技术的重要性。在本文中，作者介绍了他们在使用BTX-A治疗下半面部和颈部方面的经验，并将他们目前的做法与其他文献报道的做法进行了比较和对比。
