Botulinum Toxin on the Neck
The use of toxin botulinum A (BTXA) for aesthetic indications continues to grow in popularity due to its safety, quick effects, and short recovery time. Its use on the neck to improve vertical and horizontal lines is becoming more common, due to the better understanding by physicians of the role of the contraction of the platysma muscle during the senescent changes seen in the neck. The downward pull of the platysma over time leads to a loss of the definition of the chin and the jawline, the jowls, the vertical bands, and the horizontal rhytides. The cervical treatment can also soften the melomental fold and improve the lateral cheek lines by weakening the downward force exerted by the platysma on the structures of the lower face. Knowledge of the anatomy of this region, familiarity with toxin botulinum injection, and technical experience are crucial for the best results. This chapter discourse about the treatment of the vertical bands and the horizontal lines of the neck using botulinum toxin.
