Abstract
We have reported two rare cases of facial nerve palsy. Case 1: A 17-year-old female underwent a right sagittal split osteotomy (SSO) to correct her prognathism. Six days after the operation a right facial palsy was noted and remained moderate over 3 months. To improve it stellate ganglion blocks were performed, and the palsy remitted completely. We suppose that the cause might be due to the traction and hypoxia of the tissues induced by postoperative swelling. Case 2: A 63-year-old man has had a bilateral recurrent type of facial palsy for 6 years. The palsy had worsened attack by attack and was in severe condition (facial palsy score=3) at the fourth attack. At this time, His serum Epstein-Barr (EB) virus titers were x1280 (VCA IgG) and x640 6 months later. We suspected that the etiologies might be Sarcoidosis, Guillain-Barré syndrome, Melkersson-Rosenthal syndrome and EB virus infection. But the definitive findings were not found. We thus conjectured the etiology to be idiopathic.
