Jaw implant vs double jaw surgery - what would be the best choice for me? (photos)

I’ve only done 1 consultation with a surgeon who said that a jaw implant is applicable for my situation. The internet seems to indicate otherwise, and have told me that DJS is the only solution to my jaw disharmony. I have a perfect bite and no functional issues besides mouth breathing at night. DJS seems extremely aggressive and expensive. I’ve been considering a rhinoplasty in addition to the jaw implant. Would this be advisable? I might avoid anything if DJS is the only solution. Thanks.
