A bifid uvula is an anatomic variation that can be predictive of sub-mucous cleft palate, which may cause velopharyngeal insufficiency (VPI). Bifid uvula prevalence in the literature ranges from 0.18% to 10.3%, depending on the population studied. The aim of this study is to determine the prevalence of bifid uvula in the Geneva's school children population.
A cross-sectional study was conducted in Geneva's primary school children, from September 2014 to June 2015. An examination of the uvula was performed by dentists working for the Scholastic Dental Service, after a specific training in diagnosing bifid uvulas. The dentists recorded their findings on a standardized form.
The total number of school children in Geneva in the school year 2014-2015 was 30,375. 23,961 children had their uvula examined, representing 79% of the total population of school children. Among them, a hundred school children had a cleft uvula. One schoolgirl had no uvula. The prevalence of bifid uvula is 0.42%. Sex ratio (M/F) is 0.96.
This large study, the second in literature for number of patients examined, identified a prevalence of bifid uvula of 0.42%. This result is in agreement with previous studies.
悬雍垂裂是一种解剖变异，可预测黏膜下腭裂，而黏膜下腭裂可能导致腭咽闭合不全（VPI）。根据所研究的人群不同，文献中悬雍垂裂的患病率在0.18%至10.3%之间。本研究的目的是确定日内瓦学龄儿童中悬雍垂裂的患病率。
2014年9月至2015年6月，在日内瓦的小学生中进行了一项横断面研究。为学校牙科服务机构工作的牙医在接受了诊断悬雍垂裂的专门培训后，对悬雍垂进行了检查。牙医们将他们的检查结果记录在一份标准化表格上。
2014 - 2015学年日内瓦的学龄儿童总数为30375人。23961名儿童接受了悬雍垂检查，占学龄儿童总数的79%。其中，100名学龄儿童有悬雍垂裂。一名女学生没有悬雍垂。悬雍垂裂的患病率为0.42%。性别比（男/女）为0.96。
这项大规模研究是文献中患者检查数量第二多的研究，确定悬雍垂裂的患病率为0.42%。这一结果与先前的研究一致。
