Clinical Practice and Cases in Emergency Medicine

Case Presentation: A 26-year-old male presented to our emergency department for six days of right-sided facial myasthenia and parasthesias following a dental procedure using anesthetic nerve blocks.

Discussion: Iatrogenic cranial nerve VII neuropraxia, a peripheral nerve injury, is an uncommon complication of alveolar nerve blocks with few documented cases specifically due to dental anesthesia. Treatment usually involves use of oral corticosteroid and/or antiviral medications along with close follow-up in clinic with a neurologist and/or otolaryngologist.
