Subjects and Methods: A total of 396 patients initially diagnosed with Bell\u2019s palsy that had visited the Department of Neurology of Chang Gung Memorial Hospital, Taoyuan, a tertiary referral medical center in Taiwan, between January 2014 and December 2018 were included. Medical records, facial electroneurography (fENoG), and blink reflex (BR) tests were reviewed and analyzed. A favorable outcome was defined as patients who improved to grade \u2264 II, and an unfavorable outcome was defined as patients who improved to grade \u2265 III in 6 months according to the House\u2013Brackmann (HB) grading system. Results: The rate of favorable outcomes was 89.4% (354 of 396 patients) at the 6-month follow-up. A favorable outcome (HB less than grade II) was associated with a delayed BR (odds ratio, OR, 5.38; 95% CI, 1.82 to 15.90) and fENoG values (the lesion side\/the healthy side) over 33% (OR, 6.67; 95% CI, 3.02 to 14.71). The recovery time was significantly shorter for those with a delayed BR than for those with an absent BR and shorter for those with good fENoG values (&gt;33%) than for those with poor values (\u226433%). However, treatment without or with different doses and durations of oral glucocorticoid did not influence the final outcome or recovery time in this study. Conclusions: The fENoG and BR tests were significant and highly valuable examinations for predicting the final outcome. Moreover, age younger than 60 years, a delayed BR, and fENoG values &gt; 33% were associated with shorter recovery times.<\/jats:p>","DOI":"10.3390\/jpm11030171","type":"journal-article","created":{"date-parts":[[2021,3,2]],"date-time":"2021-03-02T10:36:37Z","timestamp":1614681397000},"page":"171","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Reappraisal of the Prognostic Factors of Outcome and Recovery Time in Patients with Idiopathic Bell\u2019s Palsy: A Retrospective Single-Center Analysis"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7109-2745","authenticated-orcid":false,"given":"Chi-Hao","family":"Peng","sequence":"first","affiliation":[{"name":"Division of Chinese Internal Medicine, Center for Traditional Chinese Medicine, Chang Gung Memorial Hospital, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiun-Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Chinese Internal Medicine, Center for Traditional Chinese Medicine, Chang Gung Memorial Hospital, Taoyuan 333, Taiwan"},{"name":"School of Traditional Chinese Medicine, College of Medicine, Chang Gung University, Taoyuan 333, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming-Feng","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei 105, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung-Lung","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei 105, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui-Ching","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Traditional Chinese Medicine, Division of Chinese Acupuncture and Traumatology, Chang Gung Memorial Hospital, Taipei 105, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Long-Sun","family":"Ro","sequence":"additional","affiliation":[{"name":"Department of Neurology, Chang Gung Memorial Hospital, Taipei 105, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,2]]},"reference":[{"key":"ref_1","first-page":"1204","article-title":"Bell\u2019s Palsy","volume":"2014","author":"Holland","year":"2014","journal-title":"BMJ Clin.
