Hello and thank you for this great question. Both during your procedure, and especially during the first two to three weeks after your procedure, your board certified facial plastic surgeon will recommend lying on your back with your head elevated. Doing so will help minimize swelling as well as any direct impact to your surgical areas. Lying on your back will also help ensure you will heal evenly, without visible differences on one side or the other. After two to three weeks, you can once again sleep on your side, if that is more comfortable to you, without worrying about impacting your results. I hope this information helps you. Good luck with your procedure! - Jacqueline T. Cheng, MD
