This book, containing more than 200 cadaveric photos and 200 illustrations, aims to familiarize physicians practicing botulinum toxin type A (BoT-A) and filler injection with the anatomy of the facial mimetic muscles, vessels, and soft tissues in order to enable them to achieve optimum cosmetic results while avoiding possible adverse events. Anatomic considerations of importance when administering BoT-A and fillers are identified and in addition invaluable clinical guidelines are provided, highlighting, for example, the preferred injection points for BoT-A and the adequate depth of filler injection. Unique insights are also offered into the differences between Asians and Caucasians with regard to relevant anatomy.
