But the lack of a visible nose bone doesn’t mean that your baby definitely has Down syndrome. Babies without Down syndrome can also appear to be missing a nasal bone on a scan, particularly if they’re non-Caucasian. These images show scans that looked for the nasal bone at the bridge of two babies’ noses.
Does absent nasal bone always mean Down syndrome?
If the ratio were 11 or greater, 69% of fetuses with Down syndrome would be identified, compared with 5% of euploid fetuses. Conclusions: The absence of a nasal bone is a powerful marker for Down syndrome. A short nasal bone is associated with an increased likelihood for fetal Down syndrome in a high-risk population.
Can nasal bone grow after 12 weeks?

How important is nasal bone on ultrasound?
Furthermore, the absence of the nasal bone or its hypoplasia is one of the sonographical markers for helping the diagnosis of Down’s syndrome. In 2001, it was found that the nasal bone is absent in 60-70% of the fetuses with Down’s syndrome and 2% of normal fetuses in 11-14 weeks ultrasound.
How can an ultrasound detect Down syndrome?
An ultrasound can detect fluid at the back of a fetus’s neck, which sometimes indicates Down syndrome. The ultrasound test is called measurement of nuchal translucency. During the first trimester, this combined method results in more effective or comparable detection rates than methods used during the second trimester.

Women who are 35 years or older when they become pregnant are more likely to have a pregnancy affected by Down syndrome than women who become pregnant at a younger age.3–5However, the majority of babies with Down syndrome are born to mothers less than 35 years old, because there are many more births among younger women
