At birth it consists of right and left halves, joined by a suture that usually closes during infancy.The bone which forms the forehead and protects the frontal lobes of the brain. In the substance of the bone is a cavity on each side (the frontal sinus) which communicates with the nose. Catarrh in these cavities produces the frontal headache characteristic of a ‘cold in the head’, and sometimes infection known as sinusitis develops.
