The frontal sinus is one of the four major sinuses in the skull. The development process of these four paired sinuses differ from one another. The sphenoid and frontal sinuses are both pneumatized after birth, and not fully grown until late adolescence. 1 The frontal sinuses are two sinuses located within the frontal bone in the posterior section of the supercilliary arches. They are rarely symmetrical; the septum between these two sinuses frequently deviates from the midline. On rare occasions, one or both sinuses may be absent. 2 A large asymmetry between both frontal sinuses can occur in the same individual separately. The pneumatization of the frontal sinus is highly variable, ranging from aplasia to hyperplasia. The predominance of supercilliary arches does not influence the presence, absence, or size of the frontal sinus. 3 A typical series of CT scans for the sinuses uses less x-ray radiation than a standard complete set of x-rays. However, a CT scan of the sinuses does not show any brain tissue.
