From the photo, it seems that it is mainly the mandibular angle. I suggest you go to the hospital for a doctor's examination, and then discuss the detailed operation plan with the doctor.

(Dr. Liu Lei from West China Stomatological Hospital solemnly reminds me that because I can't meet the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
