THE MAXILLARY SINUSES

. Posted in HEALTHY BODY

The maxillary, or cheek, sinuses are fairly well developed at birth, although they will become larger as the rest of the body continues to grow. The maxillary sinuses are housed in the cheekbones. The roof of the maxillary sinus forms the floor of the space, called the orbit, that houses the eyeball. The floor of the maxillary sinus forms part of the hard palate. Both baby and adult teeth in your upper jaw form in this
area. As the teeth drop down, they push through the floor of the maxillary sinus into the mouth. The nerve that feeds into your teeth, your cheeks, and the maxillary sinus is the trigeminal or cranial nerve V. This nerve runs through the roof of the maxillary sinus and provides sensation to your facial skin.
