However, there is a deficiency that is compensated by the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth of ethmoid and the inferior concha. The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. Most of these ostia communicate with the nose through the lateral nasal wall, via a semi-lunar depression in it known as the infundibulum. The infundibulum is bound laterally by a projection known as the uncinate process. The roof of each nasal cavity
