It is a chronic inflammation characterized by atrophy or degeneration of nasal mucosa. The development is slow, the course of disease is long, and women are more common. The weak constitution is more common than the strong constitution. The symptoms of this disease are atrophy of nasal mucosa, loss or disappearance of sense of smell, and excessive nasal scab. In severe cases, the eardrum and nasal bones will also shrink. The atrophic changes of mucosa can develop downward to nasopharynx, oropharynx, laryngopharynx and other mucosa.

symptom

1. Nasal congestion is caused by nasal scab obstruction. Or because the sensory nerve of the nasal mucosa is atrophied and the sensory disorder is dull. At this time, although the nasal cavity is not ventilated, the patient is "nasal congestion."

2. The trunk of mouth and nasopharynx is caused by atrophy of nasal mucosa glands, decreased secretion or long-term mouth breathing due to nasal congestion.

3. Nosebleeds are caused by atrophy, thinning and dryness of nasal mucosa, or capillary rupture caused by nose digging and forced blowing.

4. The loss of sense of smell is caused by the atrophy of mucosa in the olfactory region.

Most people with bad breath have a special rancid smell. It is produced by protein decomposing pus scab. Patients themselves do not feel the loss of sense of smell, and others can hear it nearby, so severe cases are also called smelly noses.

6. Headache, dizziness, atrophy of nasal mucosa, loss or lack of temperature regulation and moisturizing function, caused by inhalation of cold air stimulation or pus and scab oppression. Mostly manifested as forehead, temporal or occipital headache.
