- Frontal- one sinus per side, located within the bone of the forehead above the level of the eyes and nasal bridge (figures 1 and 3). Sphenoid- one sinus per side, located behind the ethmoid sinuses; the sphenoid is not seen in a head-on view but is better appreciated looking at a side view (figure 3). The pink membranes lining the sinuses make mucus that is cleared out of the sinus cavities and drains into the nasal passage.

Blood-filled sinuses Paranasal air sinuses. The air sinuses, four on each side, are cavities in the bones that adjoin the nose. They are outgrowths from the nasal cavity and retain their communications with it by means of drainage openings, or ostia. Consequently, their lining is mucous membrane similar to that found in the nose.

Paranasal sinuses The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes. The sinuses are named for the facial bones in which they are located.

PARANASAL SINUSES ANATOMY PARANASAL SINUSES ANATOMY. 1  Air cavities, which in the nasal cavity are paired, between certain bones in the skull are known as paranasal sinuses. The bones which surround these sinuses and create the cavity are also responsible for the naming of the particular sinus.

What are Paranasal Sinuses? These 10 animal facts will amaze you. The paranasal sinuses are spaces within the bones of the skull and face, which are filled with air. These open spaces serve the purpose of warming and humidifying the air we breathe, as well as giving resonance to the voice.

Sinus Cavities (Paranasal Sinuses) Location, Anatomy, Pictures The maxillary sinuses are the largest of the paranasal sinuses and located in the body of the maxilla (upper jaw). It is the sinus that is the most likely to become infected and given its size and close proximity to other key structures on the skull, there is a risk of the infection spreading.

Maxillary sinus The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, and drains into the middle meatus of the nose. It is the largest air sinus in the body.

Sinusitis Sinusitis is inflammation of the sinuses. It occurs as the result of an infection from a virus, bacteria, or fungus. The sinuses are air-filled spaces in the skull. They are located behind the forehead, nasal bones, cheeks, and eyes. Healthy sinuses contain no bacteria or other germs. Most of the time, mucus is able to drain out and air is able to flow through the sinuses. When the sinus openings become blocked or too much mucus builds up, bacteria and other germs can grow more easily.

Nose, Nasal Cavities, & Paranasal Sinuses Paranasal sinuses are air-filled cavities in the frontal, maxilae, ethmoid, and sphenoid bones. These sinuses, which have the same names as the bones in which they are located, surround the nasal cavity and open into it.

Sinus Development in Children At birth these sinuses are the size of a pea. The ethmoid sinuses are located on each side of the nose, between the eyes. Made of very thin bone, they grow to their adult size, about the size of a matchbox, by adolescence. The maxillary sinuses are in each cheek, sitting above the teeth and below the eyes.

- The Frontal Sinuses are air-filled cavities which lie between the lamina of the frontal bone. The size and shape of this sinus varies among individuals. Frontal Sinusitis occurs from the inflammation of the Frontal or Ethmoid Sinuses. The Frontal Sinuses drain into the nose through the Ethmoid Sinuses. If there is any obstruction or blockage of the Ethmoid Sinuses, this usually causes inflammation of Frontal Sinuses, which results in impaired mucus drainage.
