Q. My 5 month old was just diagnosed with a sinus infection and puton antibiotics, but my friends all tell me that my baby doesn't evenhave sinuses yet. Does she?A. It is a common misunderstanding that infants do not have sinuses.
Infact, babies are born with sinuses, but they are just not very welldeveloped. Newborns have very small maxillary (under your cheeks) andethmoid sinuses (between your eyes), but they can't be seen on regularxrays until a child is 1-2 years old.
The frontal sinuses (whichoften contribute to typical adult sinus headaches) and sphenoid sinusesdon't begin to develop until a child's second year and can't be seen onan xray until the child is 5-6 years old. The sinuses continue to growuntil your child is a teenager.
How long had your child been sick?
Ifit had been for more than 10-14 days, then she may very well have asinus infection. But whether or not she could have a sinus infection iscontroversial. Most likely, even if she has a green or yellow runnynose for several weeks, instead of a real sinus infection, it would bemore appropriate to just call it purulent rhinitis. If it was lingeringand getting worse, you would still treat her with antibiotics though.
If she has only been sick for 5-7 days, then she may just have a cold.
