Occurrence of sequelae in Bell's palsy.
The occurrence of sequelae in 330 patients with Bell's palsy followed up for more than 6 months was investigated. At least one of five kinds of sequelae (synkinesis, crocodile tears syndrome, spasm, contracture, tinnitus and/or hearing loss during facial movement) was observed in 30 of the 330 cases (9.1%). Sequelae occurred at 23.9-39.0 weeks (mean) after onset of palsy and at scores of 30-34 points (mean; full score 40 points). The incidence of sequelae was correlated to the degree of facial nerve dysfunction.
