A CASE REPORT OF TREATMENT OF MASSETERIC HYPERTROPHY WITH BOTULINUM TOXIN

• Choi MG

Abstract

The treatment of hypertrophy of the masseter has to been dominated by conservative and surgical measures. Local therapy with type A botulinum toxin permits an alternative method of treatment. After targeted, intramuscular injection of the affected muscles, marked inactivity atrophy occurred in the muscles of patients over the course of 3 to 8 weeks. It has been proven that the atrophy remained constant over a long peroid and no side effects were abserved. Because of its minimal invasiveness, this technique seems to have an advantage over conventional surgical therapy. Consequently, treatment with type A botulinum toxin can be regarded as a sensible alternative to surgery in cases of hypertrophy of the masseter muscles.
