Nose: From 3 Different Sources


The uppermost part of the respiratory tract, and the organ of smell. The nose is an air passage connecting the nostrils at its front to the nasopharynx (the upper part of the throat) at its rear. The nasal septum, which is made of cartilage at the front and bone at the rear, divides the passage into 2 chambers. The bridge of the nose is formed from 2 small nasal bones and from cartilage. The roof of the nasal passage is formed by bones at the base of the skull; the walls by the maxilla (upper jaw); and the floor by the hard palate. Three conchae (thin, downward-curving plates of bone) covered with mucous membrane project from each wall.Air-filled, mucous membrane-lined cavities known as paranasal sinuses open into the nasal passage. There is an opening in each wall to the nasolacrimal duct, which drains away tears. Projecting into the roof of the nasal passage are the hair-like endings of the olfactory nerves, which are responsible for the sense of smell.

A main function of the nose is to filter, warm, and moisten inhaled air before it passes into the rest of the respiratory tract. Just inside the nostrils, small hairs trap large dust particles and foreign bodies. Smaller dust particles are filtered from the air by the microscopic hairs of the conchae. The mucus on the conchae flows inwards, carrying microorganisms and other foreign bodies back towards the nasopharynx to be swallowed and destroyed in the stomach.

The nose detects smells by means of the olfactory nerve endings, which, when stimulated by inhaled vapours, transmit this information to the olfactory bulb in the brain.

The nose is susceptible to a wide range of disorders. Allergies (see rhinitis, allergic), infections such as colds (see cold, common), and small boils are common. Backward spread of infection from the nose occasionally causes a serious condition called cavernous sinus thrombosis. The nose is also particularly prone to injury (see nosebleed; nose, broken). Obstruction of the nose may be caused by a nasal polyp (a projection of swollen mucous membrane).

Noncancerous tumours of blood vessels, known as haemangiomas, commonly affect the nasal cavity in babies. Basal cell carcinoma and squamous cell carcinoma may occur around the nostril. The nose may also be invaded by cancers originating in the sinuses.

In the course of RESPIRATION, incoming air enters via the nose and is here warmed, moistened, and ?ltered before entering the lungs. The nose has a protective function, irritant air being expelled by SNEEZING. It is also the organ of SMELL.

Several sinuses (see SINUS) lie concealed in the bones of the SKULL, into which air enters freely by apertures connecting them with the nose. These cavities occupy spaces in the frontal bone over the eyebrow (frontal sinus); in the upper jaw-bone, ?lling in the angle between the EYE and the nose (maxillary sinus); in the sphenoid bone (sphenoidal sinus); and in the lateral part of the ethmoid bone (ethmoidal sinus). The sinuses drain into the interior of the nose, as does the Eustachian or auditory tube from the middle ear (see EAR).

n. the organ of olfaction, which also acts as an air passage that warms, moistens, and filters the air on its way to the lungs. The external nose is a triangular projection in the front of the face that is composed of cartilage and covered with skin. It leads to the nasal cavity (internal nose), which is lined with mucous membrane containing olfactory cells and is divided into two chambers (fossae) by the nasal septum. The lateral wall of each chamber is formed by the three scroll-shaped *nasal conchae, below each of which is a groovelike passage (meatus). The *paranasal sinuses open into these meatuses.

Nose, Disorders Of

Certain skin diseases – particularly CHILBLAIN, ACNE, LUPUS and ERYSIPELAS – tend to affect the NOSE, and may be very annoying. Redness of the skin may be caused by poor circulation in cold weather.

Acute in?ammation is generally the result of a viral infection (see COLD, COMMON) affecting the mucous membrane and paranasal sinuses (see SINUSITIS); less commonly it results from the inhalation of irritant gases. Boils may develop just inside the entrance to the nose, causing pain; these are potentially troublesome as infection can spread to the sinuses. HAY FEVER is one distressing form of acute rhinitis.

Malformations are of various kinds. Racial and familial variations in the external nose occur and may be a reason for RHINOPLASTY. Di?erences in the size and shape of the nose occur, often forming the starting point for chronic in?ammation of the nose, perennial rhinitis (all the year round), hay fever, or ASTHMA. More commonly, obstruction results from nasal polyps or adenoids, leading to inhalation through the mouth. Adenoids are an overgrowth of glandular tissue at the back of the throat, into which the nose opens. Polyps are growths of soft jelly-like character: they arise from chronic in?ammation associated with allergic rhinitis, chronic sinusitis, asthma, and aspirin abuse. Large polyps can cause erosion of the nasal bones and should be surgically removed.

Bleeding (see HAEMORRHAGE).

Foreign bodies At ?rst these may not cause any symptoms, but in time they can cause obstruction of the affected nostril with a foul-smelling bloody discharge. The problem is common with small children who tend to push small objects into their noses. Foreign bodies require removal, sometimes in hospital. Anyone attempting to remove a foreign body should take care not to push it further into the nose.

Loss of sense of smell, or anosmia, may be temporary or permanent. Temporary anosmia is caused by conditions of the nose which are reversible, whereas permanent

anosmia is caused by conditions which destroy the OLFACTORY NERVES. Temporary conditions are those such as the common cold, or other in?ammatory conditions of the nasal mucosa or the presence of nasal polyps (see above). Permanent anosmia may follow in?uenzal NEURITIS or it may also follow injuries to the brain and fractures of the skull involving the olfactory nerves.

Injury to nose The commonest injury is a fracture of the nasal bones or displacement of the cartilage that forms the bridge of the nose. The nasal SEPTUM may also be displaced sideways by a lateral blow. Sporting activities, especially boxing and rugby football, are commonly a cause of nasal injury. If a fracture is suspected, or if there is substantial tissue swelling, an X-ray examination is necessary. Resetting a damaged bone should be done either immediately, before swelling makes surgery di?cult, or ten days or so later when the swelling has subsided. Results are usually good, ensuring a clear airway as well as a restored pro?le. It is not unusual for the cheek-bone to sustain a depressed fracture at the same time as the nose is broken. Careful assessment and prompt surgery are called for. (For more information on fractures, see under BONE, DISORDERS OF).

Rhinitis In?ammation of the MUCOUS MEMBRANE lining the nose. Symptoms include nasal discharge and obstruction, sneezing and sometimes pain in the sinuses. There are several types of rhinitis:

•Allergic – due to allergy to dust, pollen or other airborne particles. Also called hay fever, allergic rhinitis causes a runny nose, sneezing and local congestion. It affects up to 10 per cent of the population and is more common in people suffering from other allergic disorders such as asthma or eczema (see DERMATITIS). Skin tests help to identify the causative ALLERGEN which the sufferer can then try to avoid, although in the case of pollen this is di?cult. Decongestant drugs, ANTIHISTAMINE DRUGS, and CORTICOSTEROIDS may help, as can SODIUM CROMOGLYCATE inhaled regularly during the pollen season. A desensitisation course to a particular allergen sometimes provides long-term relief.

Atrophic rhinitis is caused by a deterioration in the nasal mucous membrane as a result of chronic bacterial infection, nasal surgery or AGEING. Symptoms include persistent nasal infection and discharge and loss of sense of smell. ANTIBIOTICS and, in some cases, OESTROGENS alleviate the symptoms.

Hypertrophic rhinitis results from repeated nasal infection, and is characterised by thickened nasal membranes and congestion of the nasal veins. Removal of thickened mucosa may help severe cases.

Vasomotor rhinitis occurs when the mucosa becomes oversensitive to stimuli such as pollutants, temperature changes or certain foods or medicines. It may occur as a result of emotional disturbances and is common in pregnancy.

Viral rhinitis occurs as a result of infection by the common cold virus; treatment is symptomatic. Sinusitis is sometimes a complication.... nose, disorders of

Nose, Broken

Fracture of the nasal bones or dislocation of the cartilage that forms the bridge of the nose. The fracture is usually accompanied by severe swelling of overlying soft tissue. A fractured nose is painful and remains tender for about 3 weeks after injury.

Resetting is usually carried out either before the swelling has started, or when it has subsided, usually about 10 days after the injury. Occasionally, a displaced bridge can be manipulated into position under a local anaesthetic, but, usually, a general anaesthetic is needed. A plaster splint is sometimes required during healing.... nose, broken

Cancer – Nose And Throat

Usually epithelioma with burning. Lesion may extend upwards into the base of the skull. Thickening of nasal membranes may cause deafness by compressing Eustachian tubes.

Nose Drops Drill

To have effect upon the nasal mucosa, drops for congestion of the upper respiratory tract should be correctly instilled otherwise they may arrive in the stomach. The patient should lie on his back with his head hanging over the edge of the bed. Drops, blood heat, should be instilled into the nostrils and the patient remain in the same position for two minutes. Drops should be used in this way for no more than three days. Ephedrine BPC, Garlic, Lobelia, Menthol, etc.

Effective oil: Tea Tree oil (1 part) to 20 parts Almond, Olive or Corn oil.

Alternative. Adopt Mecca position. Kneel down, place head on ground and tuck under. The spray will reach the maximum surface of action in the nasal cavity. ... nose drops drill
