[Prognostication of sequelae in Bell's palsy].

Four symptoms of sequelae (abnormal synkinesis, facial spasm, contracture, and crocodile's tear) which persisted or appeared after 6 months from onset were examined with 351 patients with Bell's palsy. The incidence of sequelae were 2% in the group having score (May-Hosomi's modified method, 90 points method) over 40 points within 1 months after onset. Other hand, the incidence of sequelae were 15% in the group having score under 40 points at 1 weeks from onset, 30% in the group having score under 40 points at 2 weeks, 57% in the group having score under 40 points at 3 weeks, and 76% in the group having score under 40 points at 1 month. From these findings, it was seen that the prognostication with a high accuracy was possible by the score.
