Crooked face can be treated. For the treatment of crooked face, the cause of crooked face should be clearly identified first and treated for the cause. If it is caused by unilateral chewing habits, it can be treated by correcting the patient’s chewing habits or by injecting botulinum toxin and hyaluronic acid. If the jaw development is asymmetrical due to developmental causes or traumatic infections, surgical treatment is needed, usually through Botox or hyaluronic acid injections, or chin surgery to improve the patient’s crooked face. In addition, patients with systemic diseases, including intracranial tumors and intracranial inflammation, may also cause patients to have a crooked face, and it is recommended that patients go to a regular hospital for examination, diagnosis and treatment at this time.
