2D And 4D Ultrasound At 22 Weeks Shows Recessed Chin And Overbite. Concerned ?

default
Posted on Tue, 2 Oct 2012
Question: Dear Doctor,
I am concerned about my baby boy 2D ultrasound at 20 weeks, and my 4D ultrasound at 22 weeks. They both show what seems like a recessed chin and overbite (duck-like upper lip that is really prominent...). It looks nothing like the other ultrasound I've seen on google...Both baby's father and I are caucasian and have full lips, but no overbite.
I am really worried that this might be an indication of micrognathia or something else.
Please find hereunder two links to my ultrasounds:

Please advice. Best Regards,
XXXXXXX

Hello,
Thanks for posting your query.
I have seen both the photographs. Although the appearance is like that of a recessed chin, this might just be a normal variation and further development may give the face a normal shape.
Right now it is too early to comment about the facial features. These will become more clear after 30 weeks gestation.
Hope this answers your query. I will be glad to answer the follow up queries that you have.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Regards.
Dr. Rakhi Tayal.

Hello.
Thanks for writing again.
The overbite that is seen is again a developmental stage and is likely to correct on its own as the child grows. Please do not worry and go for a repeat scan at 30 weeks to see the change.
Hope my answer is helpful.
Do accept my answer in case there are no further queries.
Regards.
