If Your Mental Nerve is Very Low on Your Chin Can You Still Have a Sliding Genioplasty?

I can fill with my fingers my mental nerve in my chin. I have a short chin vertically and the mental nerve feels as if it is almost at the bottom of my bone. With my understanding of sliding genioplasty, the mental nerve is usually above where the cut is made. But when I feel with my fingers through my skin, I feel the nerve and it is basically at the very bottom of my chin. Would this cause a problem with having a sliding genioplasty done? Would it increase risk of nerve damage? Thank you!
