Introduction - In a door-to-door two-phase survey of common neurologicdiseases conducted in two Sicilian municipalities, we investigated theincidence and the lifetime prevalence of Bell's palsy (BP). Material &methods - During phase 1, we administered a screening instrument forfacial palsy to 11,901 adult persons. During phase 2, study neurologistsusing specified diagnostic criteria evaluated those subjects who screenedpositive. Results - We found 73 subjects who had experienced BP duringtheir life. The lifetime prevalence as of November 1, 1987, was 642.8 casesper 100,000 population age 15 years and above. The prevalence increasedwith age and was similar in men and women. Eighteen episodes of BPoccurred in the three years preceding the prevalence day. The averageannual incidence rate was 52.8 new episodes per 100,000 population age15 years and above. Incidence increased with age. Conclusion -Comparison with other incidence studies suggests some geographicvariability.
