A common cause for nasal airway obstruction in patients who suffer from allergic sinusitis. They are found more commonly in those with chronic allergic rhinitis or sinusitis. Large nasal polyps can interfere with nasal breathing and are often removed surgically to improve breathing and decrease chronic allergic symptoms. (27 Sep 1997) |

Synonym: cartilago septi nasi, cartilage of nasal septum, cartilaginous septum, pars cartilaginea septi nasi, quadrangular cartilage, septal cartilage. (05 Mar 2000) |
| nasal septum | The dividing wall that runs down the middle of the nose so that there are normally two sides to the nose, each ending in a nostril. (12 Dec 1998) |

| inferior nasal concha | A thin, spongy, bony plate with curved margins, on the lateral wall of the nasal cavity, separating the middle from the inferior meatus; it articulates with the ethmoid, lacrimal, maxilla, and palate bones, the above bony plate and its thick mucoperiosteum containing an extensive cavernous vascular bed for heat exchange. Synonym: concha nasalis inferior, inferior turbinated bone, turbinated body. (05 Mar 2000) |

| olfactory sulcus of nasal cavity | The narrow groove in the nasal cavity above the agger nasi that leads from the atrium to the olfactory area. Synonym: sulcus olfactorius cavum nasi. (05 Mar 2000) |
| transverse nasal groove | A single deep horizontal groove at the level of the alae, with no associated defects. Synonym: transverse nasal groove. (05 Mar 2000) |

| nasal cannula |
The nasal cannula is a device used in the hospital or at home to delivery supplemental oxygen to a patient or person in need of extra oxygen. This device is a plastic tube which fits around the head of a person and a set of two prongs which are placed in the nose or nares of the person. These prongs are where the oxygen flows out of. ...

| nasal cavity |
Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. In most mammals, it also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. ...

| nasal polyp |
Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. Nasal polyps are usually classified into antrochaonal polyps and ethmoidal polyps. Antrochaonal polyps arise from the maxillary sinuses and the ethmoidal polyps arise from the ethmoidal sinuses. Antrochoanal polyps are usually single and unilateral whereas ethmoidal polyps are multiple and bilateral. ...
