PURPOSE: To describe the incidence, @entity1 demographics, and response to treatment of benign essential @entity9663 (BEB) in a population-based cohort. METHODS: In this epidemiologic study, we searched the Rochester Epidemiology Project database for @entity1 diagnosed with @entity9663 or related disorders between 1976 and 1995. The incident rate denominator was based on a linear interpolation of decennial census data from Olmsted County. The 95% confidence interval for the incidence rate was based on the Poisson distribution. RESULTS: Olmsted County residents (n = 295) were diagnosed with @entity9663 or related disorders between 1976 and 1995. Of these, 8 @entity1 met the criteria for BEB. The calculated incidence rate of BEB is 1.2 @entity1 per 100,000 population per year (95% CI, 0.37 to 2.02). At the time of BEB diagnosis, the median @entity1 age was 61.5 years, and symptoms had been present for a median of 24 months. Four @entity1 were @entity1 and 4 were @entity1 . Four of the 8 @entity1 had @entity18711 . Three of 4 @entity1 treated with oral medications reported symptomatic improvement. Botulinum toxin injection was offered to all @entity1 , but only 4 elected treatment. All who were treated with botulinum toxin had temporary symptomatic improvement. No @entity1 underwent surgical treatment for BEB. Two @entity1 had resolution of symptoms within the follow-up period. CONCLUSIONS: BEB is a @entity395 . In this small, population-based sample, @entity1 and @entity1 were affected with equal frequency, and half of @entity1 had lower facial @entity3519 ( @entity18711 ). Only half of @entity1 with BEB elected botulinum toxin injections, and none required surgery. Disease remission occurred in 2 of 8 @entity1 .
