Epidemiological characteristic of Orofacial clefts and its associated congenital anomalies: retrospective study.

Abstract：

BACKGROUND:To evaluate the relationship between gender, ethnicity/citizenship, clinical phenotype, total prevalence, and the various congenital malformations associated with oral clefts (OC) in Italy across the period 2001-2014. METHODS:A retrospective analysis (2001-2014) was conducted based on the National Congenital Malformation Registries network of Italy (Emilia-Romagna Registry of Birth Defects [IMER] and Registro Toscano Difetti Congeniti [RTDC]), which were analyzed to investigate time trends, geographical/ethnic clusters, topography, sex ratio, and associated congenital anomalies of OC phenotypes. RESULTS:Among 739 registered cases, 29.8% were syndromic or had multi-malformed associated anomalies, compared with 70.2% having isolated orofacial cleft. Cleft lip (CL) was observed in 22%, cleft palate (CP) in 40%, and cleft lip and palate (CLP) in 38% of live births, stillbirths, and terminations of pregnancy for fetal anomaly cases. Other associated conditions were major anomalies of cardiovascular defects (39%), followed by defects of the limbs (28%), neuroectodermal defects (23%), and urogenital malformations (10%). Male-to-female sex ratio was 1:1.14 in CP, 1.22:1 in CL, and 1.9:1 in CLP. Foreigners were represented by 29% from Southeast Asia, 25% from Balkans, 25% from North-Central Africa, 9% from the East, 7% from Western Europe, and 5% from South America. Total prevalence of OC cases ranged from 0.9 (RTDC) to 1.1 (IMER) of 1000 births. CONCLUSIONS:This retrospective study provides a population-based, clinical-epidemiological description of the orofacial cleft phenomenon. As a relatively frequent congenital malformation, its social and economic impact is worthy of further study. These abnormalities can cause significant problems that may be solved or minimized by early diagnosis and treatment.
