Abstract Objectives Orofacial clefts are one of the most common birth malformations and represent a significant public health economic expenditure. The purpose of this investigation was to study the epidemiology of orofacial clefts in newborns from 1993 to 2005 in Israel. In addition, a comparison of data from the National Birth Defects Registry (NBDR) and Hospital records will be made. Methods A retrospective data review of reports to the Israeli NBDR on infants with orofacial clefts in comparison with records reviewed at 13 major hospitals, accounting for 60% of all births in Israel. Results Of 1334 newborns found to be with orofacial clefts all over Israel between 1993 and 2005, 1015 were reported to the NBDR and 319 were unreported but retrieved from hospital files. During this period, of the 976 578 live births found in the 13 participating hospitals, there were 866 newborns with orofacial clefts. Of those, 684 (79%) were nonsyndromic orofacial clefts and 182 (21%) had additional syndromes. The prevalence of nonsyndromic orofacial clefts was 7/10 000 live births, lower than reported outside Israel. Only 65% of orofacial clefts retrieved from the 13 hospitals were reported to the NBDR. A significantly higher orofacial cleft prevalence was found among non‐Jews than Jews (11 and 6 of 10 000 live births, respectively), ( P < .00 001). CL/P was found more frequently than isolated cleft palate (CP). More males had orofacial clefts than females, mostly unilateral with left side predominance. Conclusions The prevalence of nonsyndromic orofacial clefts was found to be 7/10 000 live births. The higher orofacial cleft prevalence among non‐Jews may be explained by the high prevalence of consanguinity and deprived maternal nutritional status in this population.
