Enlarged biting muscle can be improved by injection of Botox, partial excision of biting muscle, jaw angle osteotomy and other ways. 1. Botulinum toxin injection: Botulinum toxin injection is also called face slimming injection. Botulinum toxin injected into the enlarged biting muscle can block the nutritive effect of the nerve to the muscle, so that the muscle will gradually atrophy to improve the situation of biting muscle hypertrophy. 2. Partial Bite Muscle Excision: Partial Bite Muscle Excision refers to resecting the stop point of the bite muscle from the jawbone through a hidden incision in the oral mucosa, and then removing part of the hypertrophied muscle fibers to improve the hypertrophy of the bite muscle. 3. Mandibular angle osteotomy: If the bite muscle hypertrophy is accompanied by mandibular angle hypertrophy, it is necessary to remove part of the bony tissue of the mandibular angle, which can improve the bite muscle hypertrophy. Patients with enlarged biting muscle should go to the hospital in time, and the doctor will give the right treatment according to the patient’s condition.
