They have two main functions: 1) As in all sinuses, they give size without added weight and 2) They give depth to the voice.
You have the para nasal sinuses, assembled around your nose. You have maxillary sinuses, frontal sinuses, ethmoid sinuses and sphenoid sinuses around your nose. These sinuses make the area around your nose, very light in weight. The diagonally opposite part of the skull is thick and heavy. That is occipital bone for example! This has an evolutionary advantage to human being. After deep inspiration, you can float in the water, without any efforts. So these para nasal sinuses has helped you to keep your nose out of water. The opposite thick part of the skull help you in this endeavour. You can very easily understand the importance of your nose in water verses your nose out of water. That is the reason, why the para nasal sinuses are assembled around your nose. All the other advantages are accessory, probably.
Sinusitis (sye-nuss-EYE-tiss) means inflammation of the sinuses or, more specifically, the lining of the sinuses. Inflammation of the sinuses means infection in the sinuses which causes frontal headaches and nasal discharge. There are two sinuses called maxillary sinus which are in the cheek bones and frontal sinus and para-nasal sinuses around the base of the nose. You may require antibiotics, nasal decongestants, antral washouts and sometimes surgery to treat difficult cases.
The paranasal sinus is behind your nose and cheeks. http://www.cancerbackup.org.uk/Cancertype/Headneck/Typesofheadneckcancers/Paranasalsinuscancer The medical term for it is called the maxillae
The one main organ involved in the respiratory system
The nasal cavity is part of the human respiratory system.Also known as the nasal fossa, it is a small air-filled chamber behind the nose, connected via the pharynx to the larynx (voicebox) and the trachea. Above and in front of the nasal cavity are the sinuses (paranasal cavities), located inside the facial bones.The nasal cavity is lined with a mucous membrane that helps keep it moist (and helps prevent drying out of the lungs). Small hairs in the nostrils filter dust from the air you breathe.
The sinuses are mucous membrane-lined cavities in some of the skull bones surrounding the nose. They help make the skull lighter.
The body part that is referred to by the term "nasal" is the nose. This includes anything around, in, or near the nose like the paranasal sinuses, nasal cavities, etc.
Brown nasal discharge can be a sign that there is bleeding in the nose or sinuses. Which are hollow cavities in the nose. A brown nasal discharge is not normal.
lateral irontal sinus/ medial irontal sinus/ rostral frontal sinus
Sinusitis is inflammation or infection of the lining of the paranasal sinuses. There are no sinuses in the nasal cavity itself, rather they surround the nose and are joined to the nasal cavity via small orifices called ostia.
The external nose is examined. The nasal mucosa and internal structures can be observed with the use of a penlight and a nasal speculum.

The nasal cavity and the paranasal sinuses
A physician uses transillumination to look at sinuses. He shines a light up the nose to see how far the light will go.

The medical term is "paranasal sinuses." These are air-filled cavities located within the bones surrounding the nasal cavity. They are important for natural drainage and humidifying the air we breathe.
The parts of the body involved with the upper respiratory tract include: the nose, the nasal cavity, the nasal and paranasal sinuses, and the larynx and pharynx.
Sinuses are air filled cavities that surround the nasal cavity. They clean the air that is breathed in by the nose.
