Managing Masseter Muscle Hypertrophy with Botox

Masseter hypertrophy (MH) is a rare condition that can cause aesthetic and functional issues. It can affect one side or both of the muscles. Gum chewing, clenching, and/or bruxism are the most prevalent causative factors that are associated with MH. In addition to conservative management, surgical resection of the enlarged muscle and/or bone is used to treat MH. Botox or Dysport injection is a relatively new, minimally invasive method for the treatment of masseter muscle hypertrophy that offers numerous advantages over conventional surgical treatment.
