Chin implant removal. I am having my chin implant removed next week. 1st time was along with rhino/Bichectomy then it shifted?

Revision surgery was a success but I know I can't live with a foreign object and I don't look like myself. Doctor let me know he will used local anesthesia and iv sedation because he will need to shave my bone a little for the skin to reattach back and avoid my skin from hanging. Does this sound right? I am reading about sutures and taping my jaw to help with that afterwards but he didnt mention it. I am 41 and I had the medium silicon implant for exactly 45 days. Any info will be appreciated.
