Abstract

Over 92 thousand newborns (1982-1991) have been analyzed to reveal 186 infants with cleft lip and(or) palate which produced the mean frequency of clefts as 2:1000. Additionally, the forms and sides of clefts, and sex of children with clefts have been defined. The comparison of results from 1951-1965 research showed a slight increase of frequency of clefts which at that time (1951-1965) amounted at 1.7:1000. Our results correspond to the actual data of the world's literature.
