The use of botulinum toxin (BoNT) is well established in medical practice. The application of BoNT extends over many indications such as strabismus, blepharospasm, hemifacial spasm, and others. Another indication for the use of BoNT type A is the masseteric muscle hypertrophy to obtain a lower facial contouring. Authors report the treatment of 5 patients with intramuscular injection of BoNT. A high degree of patient and physician satisfaction was noted after the treatment. Authors concluded that BoNT type A can safely be considered as a noninvasive drug treatment for patients with MMH.
