What can a small nasal bone in 22 week scan mean apart from Down syndrome ?

What can a small nasal bone in 22 week scan mean apart from Down syndrome ?

Talk with the Ob-Gyn: Depending upon ethnic group and other factors, some babies will not show bone formation in the nasal bridge by 22 weeks. It is believed that having a nonossified nasal bone between 15 and 22 weeks increases the Down syndrome risk, especially in women with high risk factors.

I had a 12 ultrasound and no nasal bone was found that's it mean my baby has Down syndrome or it may be to little to tell help i'm worried please?

Needs followup: Although suspicious, it may be too early to tell for sure. Data are better for 2nd trimester ultrasounds, in the 15 to 20 week range. Please see your ob/gyn and discuss consultation with high risk OB and a plan for further testing and additional OB us. Based on epidemiology (population analysis - not necessarily true for you!): hypoplastic nasal bones - .5-1.2% normal fetuses vs. 43-62% down's. ...Read more

19 weeks pregnat blood came back negative but they can see babys bone in nose does it always mean down syndrome?

19 weeks pregnat blood came back negative but they can see  babys bone in nose does it always mean down syndrome?

Not Down's: The blood test is the gold standard for testing. I would believe that 10 times more than an indistinct shadow on a 19 week ultrasound. There are lots of false positives (meaning a condition is suspected but ends up not being true) with us screening. That's why it is just a screening. If you then have a positive screen, you move ahead to the gold standard test - in this case the blood work or amnio. ...Read more

Check with you Dr.: First check with you physician to be sure there are no medical complications. You may also have some dental concerns (grinding your teeth, sleep disturbances, etc.) but rule medical complications out first. If you physician does not find an answer, you may look into finding a doctor that deals with TMJ issues to see if this might be a cause. Treat the cause, not the effects. ...Read more

At my us at 13w5days, the NT measured 1.42mm + nasal bone good. But they said moderate ds risk due to 4.7 hCG reading. Is this common?

No.: The human Chorionic Gonadotropin hormone, "hcg" level, starts low and increases as a healthy fetus grows. It is used as a measure of a fetus' appropriate growth and viability. If your HCG level is truly very low that usually suggests the fetus is not viable. (healthy and normal). ...Read more
