Empty nose syndrome is currently considered to be a medical disorder, often caused by excessive removal of the turbinates during surgery. The patient’s nasal cavity is actually wide and clear, but the patient has symptoms such as nasal congestion and difficulty in breathing, a feeling that does not actually correspond to the facts.
In contrast, there are more types of rhinitis with complex causes, which may be caused by infection with virus, endocrine disorders, immune dysfunction, long-term exposure to dust, exposure to certain drugs, etc. Most patients with rhinitis will have symptoms such as nasal congestion, increased nasal mucus, sneezing and nasal itching, and the symptoms associated with rhinitis do exist objectively.
