title: Prevalence of cleft lip and palate in western Slovakia in the years 2001-2007.
abstract: OBJECTIVE
  The aim of this study was to investigate the prevalence of orofacial clefts (OC) in live newborns from 2001 to 2007 in Western Slovakia and correlate their occurrence with a number of relevant seasonal and geographical factors and epidemiological trend of this condition. In this study we used retrospective active survey collecting clinical data of 220 children with OC registered and operated at the cleft centre in Bratislava. Our study group included 67 patients from Bratislava region and 151 patients from the remaining Western Slovakia (Nitra, Trnava, Trenčín regions). Data of live births was obtained from Health Statistics of the Slovak Republic.
  
  
  RESULTS
  Total incidence (TI) of 1.49/1000 live births (LB) in the region of Western Slovakia in 2001-2007 marked a decrease of prevalence compared to 1.64/1000 LB in the years 1985-2000. Bratislava region dominated in total prevalence of 1.82/1000 LB compared to the rest of Western Slovakia regions with 1.37/1000 LB. Most observed cleft type was the CP with 38.6 % frequency, followed by CLP with 35.5 % and CL with a frequency of 24.1 %. The frequency of AM with 1.82 % was the lowest.
  
  
  CONCLUSIONS
  The results showed that the frequency risk rate of a birth of a child with OC was 1 to 671 LB in Western Slovakia. The data proved a higher prevalence of OC in Bratislava region with 1 child with this type of congenital anomaly to 549 LB compared with 1 child with OC to 730 LB in the rest of the Western Slovakia regions (Tab. 7, Ref. 16).
