Patients with a high chin and a low chin can be corrected by the following methods: 1. Local micropigmentation: If the difference is not significant, local micropigmentation can be done by implanting own fat to alleviate the high and low chin on both sides. 2. Surgical removal of excess bone: If the developmental abnormality is more serious in appearance, surgical treatment needs to be considered to surgically remove excess bone to make the chin symmetrical bilaterally. Through the above two methods, the clinical symptoms of a high chin and a low chin can be corrected. Patients who use micropigmentation also need to avoid local trauma after surgery, otherwise it may lead to treatment failure and affect local appearance. Therefore, patients who have a high chin and a low chin should be seen and treated at an early stage.
