To analyze some clinical and epidemiologic aspects of Bell's palsy (BP) and to develop relevant correlations between existing data in literature and those obtained in this research.
From January 2012 to December 2014, 372 consecutive patients diagnosed with BP were studied retrospectively. We reviewed the patients' data including gender, age, occupation, clinical manifestations, comorbid disease, and the rate of recurrence.
The highest incidence was identified in those between 39 and 50 years of age. BP was more frequent in warm seasons (spring and summer) with its incidence reaching a peak value in September. The seasonal incidence of BP was significantly higher in summer (p < 0.05). In addition, diabetes mellitus was the most common accompanying comorbid condition.
The peak age when BP showed up was in the fourth decade of life and 55.1% of patients belonged to the male gender. BP has been observed to have the highest incidence during warm seasons (spring and summer). Diabetes mellitus was the most common comorbid condition accompanying BP. In addition, a recurrence was more likely to occur in the first 1.5 years after its first incidence.
分析贝尔面瘫（BP）的一些临床和流行病学特征，并在文献现有数据与本研究所得数据之间建立相关联系。
对2012年1月至2014年12月期间连续诊断为BP的372例患者进行回顾性研究。我们回顾了患者的数据，包括性别、年龄、职业、临床表现、合并疾病以及复发率。
39至50岁年龄段的发病率最高。BP在温暖季节（春季和夏季）更为常见，9月份发病率达到峰值。BP的季节性发病率在夏季显著更高（p < 0.05）。此外，糖尿病是最常见的合并疾病。
BP出现的高峰年龄在人生的第四个十年，55.1%的患者为男性。观察发现BP在温暖季节（春季和夏季）发病率最高。糖尿病是BP最常见的合并疾病。此外，首次发病后的前1.5年内更易复发。
