We report a case of a 65-year-old man who developed peripheral facial nerve paralysis after perioperative infiltration of lidocaine and successful biopsy. He was then observed by his daughter to have a crooked smile and slurred speech after going back to in-patients department. The clinical signs of facial paralysis started to regress 1 hour later, and then, the facial nerve paralysis was resolved completely with no neurological sequelae after another 2 hours. We assumed this to be caused by the direct action of the local anesthetic agent on the facial nerve.
