Facelift surgery takes several hours (done carefully, completely, and properly) in the operating room, and general anesthesia regimens utilizing "standard" inhalation anesthetics have as high as 30% nausea rate. Vomiting after facelift can cause hematomas requiring re-operation, so even the best surgeons with skillful techniques can have their careful surgery "undone" by post-operative nausea and vomiting (PONV). Overnight stays are one way of trying to compensate for these concerns. Pills, suppositories, and injections of anti-nausea medications don't always work to prevent PONV from these drugs, and sometimes from the narcotic pain medications as well. That is the reason I stopped doing facelift surgery in hospitals or hospital-affiliated surgicenters over 20 years ago, and instead began doing all of my elective cosmetic surgical procedures in our own AAAASF-accredited on-site office surgical facility, where we can offer BETTER anesthesia options, such as TIVA (total intravenous anesthesia) which allow PONV rates in the low single digits (our latest rates are at 3.5%, including 7-hour lower body lifts and other "big" operations such as facelifts, eyelids, and browlifts done all at one operation). For the past 21 years we have performed all of our cosmetic surgeries as outpatient procedures, so NO ONE is hospitalized overnight. Out-of-town patients are asked to stay in town overnight, and are seen by me the following morning after they check out of their hotel and before returning home. Many of my plastic surgical colleagues who operate their own accredited surgical facilities have similar statistics (and offer similar better anesthesia practices that allow these kinds of results with outpatient ambulatory procedures). It's not about OUR surgical skill or expertise--it's about the difference anesthetic practices make! You don't HAVE to stay overnight in a hospital, but it may be best with certain anesthetic choices. Ask your surgeon where he or she does their facelift surgery, what type of anesthetic is used, and what the PONV rate is. You may be surprised at the answer. You may also want to ask if your anesthesiologist stays in the operating room for the entire surgery, or if they just "supervise" your actual anesthesia provider. Best wishes! Dr. Tholen
