Wide jawbone in boys may be caused by congenital genetic factors, acquired trauma, developed masticatory muscles, etc. Treatment mainly includes medication and surgery. 1. Medication: Botox can be injected into the jawbone if the jawbone is wide due to well-developed masticatory muscles and hypertrophy of biting muscles. Botulinum toxin is a face-slimming injection, the main effect is to block the release of acetylcholine from the nerve endings, the muscles do not have the stimulation of acetylcholine, not up to the threshold strength of contraction, and gradually shrinkage will occur, which also achieves the purpose of face-slimming. The above drugs need to be used under the guidance of a doctor to avoid self-medication. 2. Surgical treatment: Surgical treatment can be considered for patients with wide bony mandibles due to congenital genetic factors, antibodies after botulinum toxin injection, and patients with wide deformed mandibles caused by acquired trauma. Surgical options mainly include osteotomy and orthopedic surgery, bone grinding and orthopedic surgery, and liposuction surgery.
