Can facial abnormalities be detected on ultrasound?

A 3D fetal ultrasound can detect facial abnormalities or neural tube defects. Typically, a fetal ultrasound offers reassurance that a baby is growing and developing normally.

What are the abnormalities of the face?

Common craniofacial anomalies include: cleft lip and palate: a separation in the lip and the palate. craniosynostosis: premature closure of the soft spots in an infant’s skull. hemifacial microsomia: a condition in which the tissues on one side of the face are underdeveloped.

When can you see facial features on an ultrasound?

27-40 Weeks: Generally, by this time the baby is head down, which is preferred. 27 to 40 weeks is the best time to get the up-close detailed pictures of the baby’s face in 3D/4D.

What causes facial abnormalities?

Craniofacial malformations, including craniosynostosis, are the result of an infant’s skull or facial bones fusing together too soon or in an abnormal way. When the bones fuse together too early, the brain can become damaged as it grows and cannot expand properly, and the infant may develop neurological problems.

When to have an ultrasound of the fetal face?

Therefore, any time a fetal anomaly is identified, the diagnostic workup should include a detailed examination of the fetal face. Apart from obvious malformations, such examinations may also identify subtle dysmorphism that may be crucial for a definitive diagnosis.

Can a 2D ultrasound be used to diagnose facial anomalies?

Apart from obvious malformations, such examinations may also identify subtle dysmorphism that may be crucial for a definitive diagnosis. With two-dimensional (2D) ultrasound, a combination of planes must be used to assess facial anomalies (Fig. 11-1). 1,3,4,6 The following discussion applies mostly to the midtrimester fetus.

How to diagnose congenital abnormalities in the face?

The nostrils typically appear as two little anechoic areas. A series of transverse scans from the top of the head moving caudally allows examination of the forehead, nasal bridge, orbits, nose, upper lip and anterior palate, the tongue within the oral cavity, lower lip and mandible.

When to visualize the fetal face and neck?

Visualization of the fetal face and neck in early gestation is an important aspect of the ultrasound examination as it has been incorporated in the first-trimester fetal risk assessment for aneuploidy ( Chapters 1 and 5 ).
