There have been no systematic reviews and meta\u2010analyses of recurrent Bell's palsy. The purpose of this study was to evaluate the clinical manifestations of recurrent Bell's palsy through a systematic review and meta\u2010analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>The SCOPUS, PubMed, Cochrane Library and EBSCO databases were searched through 1 May 2018, using the search terms \u201crecurrent Bell's palsy\u201d and \u201crecurrent facial palsy,\u201d for studies involving patients with recurrent Bell's palsy.
