The demand of botulinum toxin injection for benign masseter hypertrophy is high in Asia. Benign hypertrophy of the masseter muscle is common in Asians and contributes to an quadrangular and wide lower face. It is common to regard a slim mandible to be a beautiful appearance in Asians, and the use of botulinum toxin to improve a square jaw appearance is common. The target muscle is the masseter. During the treatment, doctors will ask patients to clench their teeth to set the boundary of the safe zone for injection. In addition, Sometimes, repeated injections of botulinum toxin may be needed in order to achieve good results. The crunching power may be reduced for 2 to 4 weeks after injection. Occasionally, disappearance of facial dimples and protrusion of muscles with crunching motion may occur.
