Abstract

Background and objective: The aim of this study was to report the prevalence of cleft lip and/or palate in two hospitals in Hawler city among children born from 1/1/2008 to 31/12/ 2008.

Methods: In a retrospective study, birth records of 22387 children from two hospitals (Maternity and Raparin Hospitals) were used to identify all children born with cleft lip and/or palate. Information about prevalence, type of cleft, site, gender, family history, and associated anomalies were investigated.

Results: The overall prevalence rate of cleft lip and palate was 0.58 per 1000 births. The prevalence of isolated cleft palate, isolated cleft lip and cleft lip and palate were 0.13, 0.09 and 0.36 per 1000 respectively. Male to female ratio was 1.6:1. Regarding the site of cleft 30.8% was on the right side, 7.7% was on the left side and 61.5% was bilateral. A positive family history was found in 15.4% of the cases and 38.5% of the cases were associated with anomalies.

Conclusion: The prevalence rate of cleft lip and palate in Hawler obstetric hospitals during 2008 was lower than that reported in Asians and Europeans, and it was slightly higher than that reported in Africans. Male predominates in all types of clefts. Higher incidence of associated anomalies was observed compared with other studies in different populations.
