Patients with rhinitis have unventilated nose because of the thickening and edema of the mucous membrane of the nasal cavity, especially in the case of turbinate mucosa hyperplasia, which can easily lead to narrower gaps for ventilation inside a very small space, thus inducing patients to have unventilated nose, and patients with rhinitis often have a large runny nose, sometimes yellow pus nasal discharge, sometimes clear water-like, which exists inside the nasal cavity and can affect the ventilation of patients. It is recommended to go to the hospital for detailed examination to confirm the diagnosis after active treatment, the nose inside can be repeatedly flushed with budesonide suspension to reduce the secretion of nasal mucus. The nasal ventilation will be significantly improved when the state of the nasal mucosa and turbinate mucosa is restored after active treatment.
