Cough up odorous dryness

Due to the effects of diseases such as atrophic pharyngitis, patients may sometimes cough up a clinical symptom of odorous dryness. Atrophic pharyngitis is often secondary to atrophic rhinitis for unknown reasons. The main pathological change was atrophy of the pharyngeal glands and mucosa. From the beginning, the secretion of mucus glands is reduced and the secretions are sticky. Subsequent to the inflammation of the submucosa, the mechanization and contraction gradually occur, compressing the mucous glands and blood vessels, hindering gland secretion and nutrient supply, causing the mucosa and submucosa to shrink and become thin. His condition is long and difficult to cure.
