Can I lay on my side after chin implant and neck lipo?

 You are early in your recovery. I would sleep only with your head elevated and not rest on the side of your face. I would advise you strongly to seek the opinion of your operating surgeon as well. 

Often plastic surgeons advise sleeping on your back and elevating your head following chin and neck surgery to avoid excess swelling and also to avoid pressure and forces on the chin that may disrupt the incision or cause other issues. With time these issues become less important. At one week there is still swelling going on and if one were to sleep on the side one may develop more swelling on one side. The incisions are not strong at this point and if one is laying on the side, pressure should be avoided around the chin incision. One should always discuss positioning with his or her plastic surgeon.
