djs is a very invasive surgery. i hope you have consulted with enough surgeons and have thoroughly understood what you would be going through. i would absolutely want to avoid a revision surgery which is a key factor in my decision making. im not sure how much deposit you have made, but i think you have time before flying over to korea to really flip through the internet/google/this forum and maybe choose 2 more clinics to consult in person before making a final decision. it's a permanent change. anything which gotta do with your upper and lower teeth/or the pro would term them as "jaw", heck, even for vline, i would 100% go to a oral maxillofacial surgeon than a random plastic surgeon. there are many reasons why these surgery are under "Oral and Maxillofacial" department. please consider the different risk involved. again, there's still time. all the best~
