Epidemiologische gegevens over schisis in Noord-Nederland, 1981-1988

– Cleft lip with or without cleft palate (CL(P)) is very frequent in the northern Netherlands. In a descriptive epidemiological study the pattern of occurrence of oral clefts in the northern Netherlands was investigated and compared to findings from other regions. Data from the EUROCAT registration on type of birth, aetiological category, localisation of the cleft, sex-ratio, maternal age, seasonal distribution and geographic distribution within the northern Netherlands were analysed and compared with the literature.

Except for the high birth prevalence of isolated CL(P) no major differences from the pattern of occurrence described elsewhere were found.
