The sinuses are basically pockets of air in the bone, 2 on the forehead, and one under each eye. The 'inner lining' of the sinuses is a thin layer of tissue. They are all interconnected with the nasal cavity, hense when you get a cold, you have the feeling that there is 'pressure on your head'
The reason for their existence is simple:
They act as natural 'Shock-absorbers'. If the head were to take a direct hit to the forehead, and if the sinuses weren't there, the impact would exert pressure on the rest of the skull. Lack of sinuses would make the skull more prone to cracking.
