Can a 4D color ultrasound detect fetal cleft lip and palate?

　　Four-dimensional color ultrasound can usually detect fetal cleft lip and palate, although it may also have certain limitations.

　　Four-dimensional color ultrasound is an advanced ultrasound imaging technology that provides high-resolution images of the fetus, including the facial features. When the fetal position is appropriate and the cleft lip or palate is relatively obvious, four-dimensional color ultrasound can detect whether the fetus has cleft lip and palate. Doctors can observe the fetal facial structure from multiple angles, improving diagnostic accuracy.

　　Four-dimensional color ultrasound has high accuracy in detecting fetal cleft lip and palate, but there are still some limitations. For mild cases of cleft lip and palate, due to the small clefts, they may be difficult to visualize during the fetal stage. In such cases, four-dimensional color ultrasound may not provide sufficient diagnostic information, leading to missed diagnoses. If the fetus is in an unfavorable position for observation during the examination, such as facing the maternal body or having limbs covering the face, it may affect the doctor's ability to observe the fetal facial structure, thereby increasing the risk of missed diagnosis.

　　Pregnant women are advised to undergo regular prenatal checkups during pregnancy and have four-dimensional color ultrasound examinations under the guidance of professional doctors. Maintaining good lifestyle habits during pregnancy can promote healthy fetal development.
