The nasal bone is imaged on prenatal ultrasound in the second trimester of pregnancy, evaluated perpendicular to the longitudinal axis of the nose, in the mid sagittal plane of the fetal face. A hypoplastic nasal bone can be defined as a ratio against the biparietal diameter, by absolute length, by gestational age-based percentiles or by multiples of the median. If absent or hypoplastic nasal bone is suspected, next steps should include detailed anatomic evaluation and aneuploidy testing. SMFM considers an absent or hypoplastic nasal bone a “soft marker” which is a “minor ultrasound finding” associated with an increased risk of aneuploidy.
Isolated Ultrasound Finding
Absent or hypoplastic nasal bone occurs in 0.1 to 1.2% of euploid pregnancies. It is associated with trisomy 21, especially when occurring with other structural anomalies or soft markers. If screening is low risk for aneuploidy, this finding is of little clinical significance and most likely a normal variant.
