How can I get rid of my deep mentolabial fold, cheek surgery?

Your photos demonstrate  rare but very visible deformity of lip/chin junction. Very likely your overbite has contributed to it to a certain degree. Fillers could fix this problem easily in experienced hands. Fat grafting is probably better and more permanent option. Good luck.

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Part of your deep labiomental fold is that your chin is vertically short. This probably represents an overall lower jaw vertical shortness due to over rotation from a significant overbite. But short of undergoing entire lower jaw surgery, a vertical lengthening geniopasty to lengthen your chin with simultaneous fat grafting to the labiomental fold will provide the best aesthetic benefit to your chin area concerns.
