A case of dysphagia following botulinum toxin injection for neck rejuvenation

Botulinum toxin type A (BTX-A) is now extensively employed for cosmetic concerns. Upper face rejuvenation, including glabella frown lines and crow's feet lines, received FDA approval for cosmetic uses. However, other off-label uses for lower face conditions have been employed for texture and contouring purposes, including masseter hypertrophy and vertical banding of the neck. BTX-A for rejuvenation of the aging neck is an effective and popular treatment with high patient satisfaction rates. Alleviating the aging appearance of the neck by BTX-A is the result of denervation of hyperkinetic platysma. Concerning an extensive area of treatment and the relationship of treated muscles with other nearby muscles, dermatologists should be aware of potential adverse effects of the BTX-A injection. We herein present a case of dysphagia following botulinum toxin injection for the treatment of platysma bands.
