Abstract

Peripheral facial nerve palsy is one of the most common cranial nerve disease. There can be multiple etiologies including trauma, infection, idiopathic conditions. In rare case, during dental treatment including extraction, peripheral facial palsy also can occur. Based on the time of onset and duration of the symptom, facial palsy could be classified on immediate or delayed. Immediate facial palsy is relatively common and mainly associated with the injection of local anesthetic. However, in case that onset of facial palsy and symptom are delayed, it is difficult to determine the pathogenesis. We report a rare case of delayed facial palsy as a complication of tooth extraction, which occurred 5 days after the tooth extraction and subsided in about 1 month and discuss the possible etiology and management.

Key Words: Facial palsy; tooth extraction; third molar; complication
