Chronic rhinitis is the nasal mucosa and submucosa of chronic inflammation. Manifested as nasal congestion, chronic swelling, called chronic simple rhinitis (chronic simple rhinitis). If the development of the nasal mucosa and nasal bones of the proliferation of hypertrophy, saying that chronic hypertrophic rhinitis (chronic hypertrophic rhinitis).
[Cause]:
(A) local causes
1. Repeated episodes of acute rhinitis or treatment is not thorough and evolved into a chronic rhinitis.
2. Due to chronic inflammation of the nearby long-term stimulation or deformities caused by poor ventilation or drainage of nasal obstruction occurred, such as chronic sinusitis, deviated septum, chronic tonsillitis or adenoid vegetation and so on.
3. Nasal medication too long, inappropriate or excessive formation of drug-induced rhinitis (rhinitis medicamentosa), commonly found in the net after a long time with intranasal.
(B) cause the body
1. The long-term chronic diseases, such as endocrine disorders, long-term constipation, kidney disease and cardiovascular disease, an extent which rendered long-term or repeated-onset nasal congestion or stasis.
2. Vitamin deficiency, such as vitamin A or C.
3. Excessive alcohol can affect the nasal vasomotor and happen obstacles.
4. Long-term use of reserpine and other antihypertensive drugs, can cause nasal blood vessels to dilate and may produce rhinitis symptoms.
(C) Environmental factors: there is cement, tobacco, coal dust, flour or chemical substances in the environment workers, nasal mucosa by physical and chemical factors stimulation and damage, can cause chronic rhinitis. Rapid changes in temperature and humidity environment, such as steel making, freezing, drying and other melt shop-floor workers, but also more prone to the disease.

Deep mucosal pathology of chronic expansion of blood vessels, especially the following turbinate most obvious changes in cavernous sinus. Mucus gland function active secretion increased. Turbinate mucosal swelling, but no obvious submucous proliferative changes in the organization.
Clinical
(A) nasal obstruction: intermittent or alternating. ① intermittent nasal obstruction: the general performance of the day, to reduce labor or exercise, at night, sit-ins, or worse when cold. ② alternating nasal obstruction: when in the lower lateral side of the nasal obstruction often heavier; transferred to another lateral lying, just not in a stuffy nose or stuffy nose on the lighter side of the nasal cavity, go to the next lateral nasal congestion or stuffy nose appear heavier; while just located in the lower side of the nasal cavity to reduce nasal congestion. In addition, the sense of smell may be impaired to varying degrees, speech was nasal occlusion. As a long-term flows through the nose and upper lip nasal vestibule can be caused by dermatitis or eczema, more common in children. The nose back into the pharynx may be, cough, phlegmatic and other symptoms.
(B) Multi-tears:'ll always be sticky mucus or purulent, even showed purulent. Purulent than those after secondary infection.
(C) examination: nasal mucosa swelling, the surface smooth, moist, general Chenganhongse. Turbinate mucosa of soft and flexible, the probe is soft reduction can be depression, but then the depression will soon remove the probe recovery, in particular, in the next turbinate is obvious. If using a ~ 2% ephedrine solution to the nasal mucosa contraction, then the turbinate was closing fast. Total nasal passage or inferior meatus with mucus or purulent discharge.
