All plastic surgery procedures require some form of anesthesia, even if minimal. The minimal amount of anesthesia is referred to as local anesthesia, where ice, vibration, numbing cream, and/or local injection is used to numb the treated area. Only the treated area is numbed, and the patient remains awake, alert, and comfortable. Nonsurgical office treatments (e.g., BOTOX® or Restylane®) are often performed via local anesthesia. Most brow lift surgery is performed with either IV (twilight) sedation or general anesthesia.
