Nationwide investigation on diagnostic methods for facial palsy

We investigated the present status concerning the performance of examinations of facial nerve function for facial palsy, based on statistics obtained from the project supported by a Grant-in-Aid for Co-operative Research (A) from the Ministry of Education. The project is called An Epidemiological and Clinical Study on the Idiopathic Facial Palsy. In an analysis of the questionnaire "individual investigation card for idiopathic facial palsy" obtained from 28 medical facilities throughout Japan between 1984 and 1986, the outline of the examinations performed for peripheral facial palsy was examined.
