Narcotics have a very high incidence of causing nausea and vomiting. This is also true of general anesthesia, much more so than the use of antibiotics.Neck liposuction is a fairly simple procedure in terms of recovery. Many patients can tolerate recovering from this procedure using only high-dose ibuprofen. The chance of developing an infection after chin and neck liposuction is exceedingly small. The only proven use of antibiotics in most elective surgery is a single dose taken before the procedure. When it comes to chin and neck liposuction, even this may be overkill. The use of antibiotics after cosmetic surgery is often beyond what is scientifically indicated. Most plastic surgeons use antibiotics for most cosmetic procedures and, as such, it is most likely considered the standard of care. Talk to your plastic surgeon if he or she feels comfortable avoiding the use of antibiotics. In regard to the risk of nausea and vomiting, narcotics are most likely the major culprit. If your procedure is scheduled to be done under general anesthesia, then there is a high likelihood of developing postoperative nausea and vomiting considering your history.If this is the case, please tell your anesthesiologist about your history of severe nausea and vomiting after the medications you took following the dental procedure. Anesthesiologists can sometimes alter which medications they use to limit the chance of postoperative nausea and vomiting. Liposuction of the chin and neck is easily tolerated without the use of general anesthesia. Each plastic surgeon has their own preference on how to do the procedure.Best of luck,Mats Hagstrom, M.D.
