A survey of congenital heart disease and other organic malformations associated with different types of orofacial clefts in Eastern China.
BACKGROUND
A high incidence of orofacial clefts is reported in China, but no data has shown the relation between cleft types and the incidence of other defects so far. The aim of this study is to assess the incidence of congenital heart diseases and other organic defects associated with different types of orofacial clefts.


RESULTS
All children with orofacial clefts, which were sought out from the Health Information System of Shanghai Ninth People's Hospital between 1(st) Jan 2009 and 30(th) Dec 2011, were enrolled in this study. All subjects underwent a thorough examination and grouped by the cleft phenotype. The numbers and types of other organic defects were recorded and analyzed statistically using SPSS 17.0. Of 2180 cases reported as having orofacial clefts, 657 (30.1%) had other congenital abnormalities, which were significantly more common in cleft palate (47.9% (329/687)) than that in cleft lip (10.6% (80/755)) or cleft lip and palate (33.6% (248/738)) (P<0.01). In subgroups, unilateral cleft lip and palate had a statistically higher incidence of associated abnormalities than bilateral cleft lip and palate (P<0.01). The most common malformation was congenital heart disease, which counted 45.1% (296/657) of all malformations. Disorders of the central nervous system (14.3%(94/657)) and Skeletal anomalies (13.1%(86/657)) were also frequently associated. Additionally, the most common defect in heart was atrial septal defect, which was 39.7% (118/296) of all congenital heart diseases.


CONCLUSIONS
As the high incidence of heart defects and other organic abnormalities in the children with cleft palate in Eastern China, special attention should be paid to them and echocardiography should be a proposed examination in the evaluation of children with cleft palate before any surgical correction being executed.
