Dry and itchy nasal mucosa
Introduction
Introduction The nasal mucosa is dry and itchy, and the capillaries are easily broken and bleeding, which is a symptom of dry rhinitis. Dryness in the nose, reduction of nasal secretions, itching, burning sensation, often induce the patient to dig the nose, causing a small amount of nosebleed, the sense of smell is generally not reduced. The anterior nasal examination showed that the nasal mucosa was dark red, the surface was dry and dull, and the nasal passages had filamentous secretions. The mucous membrane of the lower part of the nasal septum is often erosive, and there may be a small piece of thin sputum attached, often bleeding. The turbinate has no atrophy.
Cause
Cause
The nasal mucosa is stimulated for a long time, and the mucous gland is atrophied and the secretion is reduced, and the mucous membrane is thus dried. Chronic rhinitis sicca is generally thought to be caused by external physical or chemical stimuli, such as mechanical stimulation of long-term dust, effects of air overheating and excessive drying. The disease is a common occupational chronic rhinitis. It is characterized by dryness and discomfort in the nasal mucosa, less secretion, and the patient generally does not have runny nose. Because of the itching sensation in the nose, patients often dig their noses and cause nasal bleeding.
