The inspiration for writing this paper is the lack of professional and scientific papers on the selection and application of physiotherapy processes in the treatment of Bell's palsy (paresis nervus facialis) in the Republic of Croatia. By reviewing professional literature and in particular the database, it is noteworthy that the opinions of experts regarding the choice of the treatment method of this condition are greatly different.The cause of Bell's palsy is unknown or idiopathic, and hence the ways of treatment differ. Professional guidelines for physiotherapists have not yet been developed which would be used as a standard protocol for the treatment and rehabilitation of the nervous facialis paresis. The objectives of the study were to determine whether the paresis nervous facialis occurs more often at certain times of the year, whether there is a difference in the grades of manual muscle test before and after physical therapy and whether the paresis affects more specific sex. Respondents included in this retrospective study were patients from Osijek-Baranja County who were treated at the Department of Physical Medicine and Rehabilitation at the Clinical Hospital Center in Osijek since June 2016. by August 2018 years. The documentation of 50 patients with paresis nervosa facialis under code G51.0 was processed. Data was processed in SPSS (v. 16.0). The differences between the category variables were tested by a binomial test. The differences between the two independent groups of numeric variables with normal distribution were tested using Student's t-test, and among several groups using one-way variance analysis (ANOVA). Differences between dependent numeric variables that do not follow normal distribution were tested by Wilcoxon's assay. Relationships between numeric variables were investigated using a Pearson correlation test. The study found that there are differences in the manual muscle test after rehabilitation, ie the ratings have increased. Patients in the outpatient clinic with this diagnosis usually appear in January and August. Both sexes and all ages are equally obnoxious of facialis facials. It is necessary to continue research on this subject with a large number of respondents and continue to improve the techniques of physical therapy.
