Evaluation of prenatal diagnosis of cleft lip/palate by foetal ultrasonographic examination.
Ultrasound scans in the midtrimester of pregnancy are now a routine part of antenatal care in many countries. This type of screening procedure can detect serious foetal anomalies. Thanks to our registry of congenital anomalies a study was undertaken. The objective of the study was to evaluate prenatal detection of cleft lip (palate)(CL/P) by routine ultrasonographic examination of the foetus in 265679 consecutive pregnancies from 1979 to 1998. The percentage of prenatal detection of CL/P was low. For isolated malformation (foetuses with only CL/P) the detection rate was low: 17.8%; however, this detection rate increased from 5.3% during the period 1979-1988 to 26.5% during the period 1989-1998, for foetuses with associated malformations (foetuses with CL/P and one or more additional major malformations) these detection rates were 34.6, 13. 3 and 50.0%, respectively. In foetuses with associated malformations with CL/P this detection rate was higher for chromosomal abnormalities with CL/P and for non-syndromic, non-chromosomal multiply malformed children with CL/P than for non-chromosomal recognized syndromes with CL/P.
