The Paranasal Sinuses As the paranasal sinuses are continuous with the nasal cavity, an upper respiratory tract infection can spread to the sinuses. Infection of the sinuses causes inflammation (particularly pain and swelling) of the mucosa, and is known as sinusitis. If more than one sinus is affected, it is called pansinusitis.

- Frontal sinus. The frontal sinuses are pockets of space located above the orbit of each eye in the frontal bone. They are lined with mucus membrane, which secretes fluid that moistens and protects the areas it covers. The size and shape of the frontal sinus can vary from person to person. These spaces fill up with mucus, which then drain into the nose.

Anatomy and Physiology of the Nasal Cavity (Inner Nose) and Mucosa The sinuses develop as outgrowths of, and drain into, the nasal cavity. The mucosa of the sinuses connects to the nasal mucosa. Nasolacrimal ducts. Nasolacrimal ducts are the ducts which connect the lacrimal (tear) ducts in the eye to the nasal cavity.he nasal cavity functions to allow air to enter the respiratory system upon respiration. Structures within the cavity regulate the flow of air and particles it contains. The olfactory region of the nasal cavity regulates the sense of smell.

Hyperaeration of the frontal sinus â The nasal cavity and paranasal sinuses constitute an anatomical and functional unit. Paranasal sinuses communicate with the nasal cavities, which are covered by the same mucosa, via small openings and narrow ducts that allow both aeration and sinus drainage. Anatomical variations of the paranasal sinuses and nasal cavity are important in sinus diseases. Computerized tomography (CT) plays a critical role in evaluation of the patients with paranasal sinus pathology and variations.
