摘要
two young patients with bilateral facial palsy are described. they initially presented unilateral facial palsy, followed by contralateral facial nerve involvement a few days later, together with clinical and serologic evidence of acute epstein-barr virus infection. the outcome was favourable in one patient but severe sequels persisted in the second. these two cases show that this infrequent complication of epstein-barr virus infection may not always have a good outcome. the pathogenic mechanism of bilateral facial palsy is discussed.
