Fat injections can be done with either local anesthesia or twilight sedation. If you choose the former, it can be done in the office. If you choose the latter, it is done at our accredited surgery center. During twilight anesthesia, you will breathe on your own, but you will not remember anything. It is a quick acting type of anesthesia that also wears off quickly. Because you are breathing spontaneously, an endotracheal tube is usually not used.
