@entity4724 : multicentricity and increasing incidence in XXXX .

@entity5 @entity1 @entity4724
Warthin's @entity5 comprised 14 percent of all @entity5 operated on. The average @entity1 age in our series was 57.2 years. Eighty-seven percent of the @entity5 occurred in the parotid tail. The rest were in the deep lobe, or in an extraparotid location. Fifteen @entity1 had multifocal @entity5 . The maximum number of @entity5 foci in one @entity1 was six. A significant increase in the female incidence was noted with a 1.5:1 male-to-female ratio as compared with the previous male dominant ratio of 8:1. Eighty-two percent of the female @entity1 in our group were smokers. We correlated a very high incidence of cigarette smoking in our series when compared with age-matched groups in both sexes within the general population. Since it is estimated that one of eight @entity1 with @entity4724 will have multifocal disease, we suggest wider exposure and more meticulous operative exploration to avoid overlooked @entity5 foci and subsequent recurrence.
