Drooping After Scoping: A Rare Case of Peripheral Facial Nerve Palsy After RoutineEsophagogastroduodenoscopy

Peripheral facial nerve palsy is a prevalent type of mononeuropathy that can have a variety of etiologies. Facial nerve damage because of esophagogastroduodenoscopy, however, is exceedingly rare and has only been reported in 1 patient. We report the first case in the United States of a patient who developed left-sided facial nerve palsy after a routine esophagogastroduodenoscopy, with little meaningful recovery of nerve function. We hope to bring awareness to gastroenterologists of this rare complication with potential long-term detrimental effects that can be avoided with the adjustment of equipment and patient position before the procedure.
