Botox facial slimming/facial sculpting: the role of botulinum toxin-A in the treatment of hypertrophic masseteric muscle and parotid enlargement to narrow the lower facial width

Facial Plast Surg Clin North Am. 2010 Feb;18(1):133-40. doi: 10.1016/j.fsc.2009.11.014.


Botulinum toxin A is a highly efficacious and cost-effective, nonsurgical option for reducing the width and shape of the lower face and jawline. The results can vary from the subtlest thinning of the face to an extremely thin, cachectic appearance. Many nuances can be achieved. The administration is simple, and the process takes barely 5 minutes in an office setting. Botulinum toxin A can also be effectively used to reduce the bulk of an enlarged parotid gland without affecting saliva production.
