For your comfort, surgery can be performed under local anesthesia only, with light sedation combined with local anesthesia, or under general anesthesia, where you are fully asleep.
Local Anesthesia
Local anesthesia is used most commonly for straightforward surgical procedures, where patients experience little anxiety. An injection of medication numbs the area where surgery will be performed. You will be fully awake during your procedure and you should not feel any pain. Local anesthesia is not usually recommended for patients who are uncomfortable with popping and grinding noises.
