Botulinum Toxin for Mentum and Perioral Area
There is no doubt that the treatment with botulinum toxin is the most popular aesthetic procedure for facial rejuvenation. At the beginning, it was indicated only for the upper face, but now, it is frequently injected for the treatment of the lower face. When treating this area, the goal is to relax the muscles. In the perioral area, the muscle to be treated is the orbicularis oris, important for the execution of simple actions like speaking, drinking, and blowing, and which impairment would be very unpleasant. This is especially important for those who need a total competence of the lips in their jobs, like speakers, musicians, scuba divers, and others. A complete knowledge of the anatomy and the correct injection technique, not exceeding the total number of units recommended, are essential for a safe and successful treatment of the lower face. The anatomy is important not only for the perioral area treatment but also for the mentum, because of the proximity and numerous muscle intersections at this region. For example, when treating the mentum, it is possible to accidentally relax the orbicularis oris. We hope that with this chapter, we contribute for a better understanding of the lower face treatment and that after reading it, the injector feels confident to inject this region.
