What Causes Non Closure Of Posterior Fontanelle In An Infant?
My almost 7 months old son s posterior soft spot is not closed , he keeps getting dents whenever he sits in the car seat or high chair for too long and the dent becomes less visible the next day , but still can be touched . Is it normal for the posterior sport spot not to close at this age ? His anterior is still open and I know that s ok. His head has been measuring big from day 1, he is now in the 90s percentile . No other symptoms . Growing well and hitting all his milestones .

HI, thanks for using healthcare magic
The posterior fontanel closes by 2 to 3 months in most infants but the fact that he is reaching his milestones is good.
It implies that there is no neurological deficit.
His doctor may want to consider imaging such as ultrasound and blood test such as thyroid function tests, to rule out any problems.
Low levels of thyroid hormones can sometimes cause delayed closure.
I hope this helps
