Local anesthesia is easy for a brow lift since the sensory nerves are easy to block. No one worries about doing a skin test for allergy to the local, since a true allergy is extremely rare. If you know or suspect you have an allergy to a specific local anesthetic, there is another family of local anesthetics that can be used instead. Most of what people think are allergies to local are, in fact, normal reactions to a component in them to reduce bleeding. This is usually first appreciated from a dental injection, since they use very concentrated epinephrine in their injections. Most Plastic Surgeons use a dilute concentration that prevents the reaction. With the local you will generally need sedation so you do not care what is going on over your head. I generally prefer a gas rather than IV meds since the gas wears off faster. (This, of course, would be general anesthesia, but I believe it is safer, wears off faster and causes less nausea postoperatively. Very little is used since we use the local even with general anesthesia. All the general is for is so you do not feel the local injection and are comfortable otherwise.)
