Skewed chin is a facial asymmetry, mainly caused by muscle, bite or joint resorption and other factors. Generally, it can be corrected by muscle function training, hyaluronic acid injection, local filler, bone grinding and bone cutting. 1. Myofunctional training: For younger patients, the crookedness of the chin is mainly caused by functional factors, and the crookedness of the jaw can be improved through myofunctional training. 2. Hyaluronic acid injections: Using hyaluronic acid injections to augment the chin can be a quick, safe, and painless way to improve a patient’s crooked chin. It is one of the more common methods of injecting hyaluronic acid into the sunken chin to make the chin full and symmetrical, thus improving the crooked chin without any trauma. 2. Local filler: After trimming the local bones, special instruments are used to fix them, during which local depressions or missing parts can be filled in order to restore facial beauty. 3. Orthognathic Surgery: For more serious cases of crooked jaw, orthognathic surgery is needed to improve the symptoms of crooked jaw under the guidance of professional doctors. If the patient has a crooked chin, he should go to the hospital in time to clarify the cause of the disease and get the appropriate treatment in time.
