Which prenatal diagnostic approach can identify cleft lip/palate prenatally?

• A. Ultrasound
• B. Amniocentesis
• C. Blood glucose test
• D. Nuchal translucency measurement

Answer: (A)

Ultrasound imaging of the fetus is the method that allows prenatal visualization of facial structures, making it possible to identify cleft lip and, in some cases, cleft palate. During the midtrimester anatomy scan, the sonographer can assess the upper lip and the palate for gaps or discontinuities, and 3D/4D ultrasound can help clarify the presence and extent of the cleft. This imaging is specifically designed to visualize fetal anatomy, so it directly detects structural anomalies.

The other options don’t identify cleft lip/palate. Amniocentesis examines fetal genetic material and is used for chromosomal or specific genetic testing, not for visualizing facial anatomy. A blood glucose test screens for maternal diabetes risk, not fetal structure. Nuchal translucency measurement screens for chromosomal anomalies in the first trimester and also does not reveal clefts. Thus, ultrasound is the prenatal diagnostic approach that can identify cleft lip/palate.
