In a door-to-door two-phase survey of common neurologic diseases conducted in two Sicilian municipalities, we investigated the incidence and the lifetime prevalence of Bell's palsy (BP).
MATERIAL & METHODS: During phase I, we administered a screening instrument for facial palsy to 11,901 adult persons. During phase 2, study neurologists using specified diagnostic criteria evaluated those subjects who screened positive.
We found 73 subjects who had experienced BP during their life. The lifetime prevalence as of November 1, 1987, was 642.8 cases per 100,000 population age 15 years and above. The prevalence increased with age and was similar in men and women. Eighteen episodes of BP occurred in the three years preceding the prevalence day. The average annual incidence rate was 52.8 new episodes per 100,000 population age 15 years and above. Incidence increased with age.
Comparison with other incidence studies suggests some geographic variability.
在对西西里岛两个市镇进行的常见神经系统疾病的逐户两阶段调查中，我们调查了贝尔氏面瘫（BP）的发病率和终生患病率。
在第一阶段，我们对11,901名成年人使用了面瘫筛查工具。在第二阶段，研究神经科医生根据特定诊断标准对筛查呈阳性的受试者进行评估。
我们发现73名受试者一生中曾患贝尔氏面瘫。截至1987年11月1日，15岁及以上人群的终生患病率为每10万人642.8例。患病率随年龄增长而增加，男女相似。在患病率调查日之前的三年中发生了18次贝尔氏面瘫发作。15岁及以上人群的年平均发病率为每10万人52.8例新发病例。发病率随年龄增长而增加。
与其他发病率研究的比较表明存在一些地理差异。
