About this trial
This study seeks to determine whether adjunct regional nerve blocks reduce pain and anxiety in adult patients undergoing Mohs micrographic surgery for face and scalp skin cancers. Participants will be randomized to one of two arms: (1) placebo regional nerve block with sterile normal saline or (2) adjunct regional nerve block with lidocaine. All patients receive local infiltration with lidocaine for complete anesthesia.
