Yes, a SMAS facelift can be performed under local anesthesia only BUT probably should not be.A SMAS facelift means different things to different patients and surgeons. I know that may seem surprising but its true. If a SMAS facelift means the SMAS layer is elevated and released then the procedure should be performed with IV sedation or even a general anesthetic in some cases. The person's health, age, anxiety level, and areas needing improvement all need to be considered.Through the years I have found most patients under-estimate their true anxiety level (its usually higher than they think especially when it comes time to do the procedure). The increased anxiety level can affect many important parameters, such as blood pressure; it increases which is not good. Additionally, it may sounds like "less" of a procedure or "less major" when a surgeon or business suggests only local anesthesia but IV sedation (twilight, conscious sedation) and general anesthesia are both very, very safe and provide a better and safer experience for the patient, in my opinion. An additional reason for the higher safety is that to have IV sedation or a general anesthetic the procedure must be done in an accredited facility, which meets certain standards for safety and sterility. In office procedures do not have or meet these standards.I hope this helps.
