This is something I'm not sure about, but I believe that its normal for a child to have an absent frontal sinus. I might be wrong. I just rememebr that one of the functions of the sinus is to allow a deeper resonance of voice during puberty. Another preposed reason is to make the head lighter. I would still look it up , but it should give you some insight.

Hey thanks for the reply. I took the exam two days ago and that was one of the questions and I put that it was normal for a child. I tried to look it up but I could'nt find it. But I hope we are right.

In the newborn the ethmoidal sinus, which gives rise to all the other sinuses, as well as the maxillary sinus, can already be identified on x-rays.
The frontal sinus appears as a triangle at the age of four and oversteps the supraorbital margin at the age of six.
The sphenoidal sinus begins to excavate the concha sphenoidalis at the age of four and can be seen on x-rays at the age of eight, when it extends to the hypophyseal fossa.
In the twelve-year-old child all sinuses almost reach their final sizes.
However, the size and shape of all sinuses, particularly of the frontal and the sphenoidal sinuses are very different.
