Cleft lip and palate are mainly caused by open defects in bone and soft tissues, or by changes in the tissues of the cleft lip and palate that resemble the shape of a rabbit's mouth during abnormal development. Can cleft lip and palate be detected by ultrasound at 20 weeks?

At 20 weeks of pregnancy, cleft lip and palate can be detected through ultrasound examination, as the fetal limbs are gradually developing. Ultrasound can also show the size of the fetus, the amount of amniotic fluid, and whether there are any abnormalities in the fetus. It can also detect the condition of cleft lip and palate, as well as whether there are any problems with the limbs.
There are many reasons for a fetus to suffer from cleft lip and palate, which are related to genetic factors of parents, maternal care during pregnancy, and dietary habits during pregnancy. Therefore, for the sake of the baby's health, pregnant mothers must prepare for pregnancy, have a balanced and nutritious diet, and ensure that the fetus grows up in a comfortable and safe environment.
The degree of cleft lip and palate varies from mild to severe, and there are different details during ultrasound examination. As the development of cleft lip and palate deepens, the results of ultrasound examination in the later stage will also be different. Pregnant women can also do four-dimensional ultrasound to check the condition of cleft lip and palate. Pregnant women should supplement sufficient folic acid in early pregnancy to reduce the risk of fetal abnormalities, and also regularly undergo prenatal check ups.
