[Sequelae and transient sequelae-like symptoms in Bell's palsy].

Four symptoms of sequelae of Bell's palsy, such as abnormal synkinesis, facial spasm, contracture, and crocodile's tear were examined with 351 patients with Bell's palsy. As a result, it was seen transient sequelae-like symptoms which disappeared in recovery process. These 4 symptoms were divided into the persistent symptoms which persisted or appeared (sequelae) after 6 months from onset and the transient sequelae-like symptoms which disappeared before 6 months from onset (transient symptoms). The relation between the sequelae and the transient symptoms were examined. Transient facial spasm were shown only in mild cases with early cure, and it was deemed that these had no relation to sequelae. Other transient symptoms were shown in the cases with moderate and severe palsy, and it was deemed that these had a close relation to sequelae. The incidence of sequelae was 19%, and that of transient symptoms was 23%. Therefore, in order to discuss the actual behavior of the sequelae, it is important to investigate the sequelae with rejection of transient symptoms.
