Correction of Chin Asymmetry
There is no non-surgical permanent solution to your chin/jawline asymmetry. Depending upon which side of your face you favor, a bony genioplasty can be done to open up (lengthen) the left chin or close down (shorten) the right side of your chin.
Regarding the chin asymmetry, sliding genioplasty could potentially resolve this. It is a same day surgery under general anesthesia.
