In clinical practice, taking medicine for rhinitis only plays an auxiliary role. Usually, the treatment of rhinitis is mainly external medicine. Rhinitis is clinically divided into simple rhinitis, chronic hypertrophic rhinitis, atrophic rhinitis and allergic rhinitis. If it is simple rhinitis, Dafenlin spray for external use is effective, oral medicine is usually not required. If it is allergic rhinitis, it needs to use budesonide nasal spray, Fushuliang nasal spray, Neishuna nasal spray, etc. externally to the nasal cavity. When the symptoms are serious, it can be used together with oral Kairuitan. If it is chronic hypertrophic rhinitis, it is necessary to remove the external part of the inferior turbinate under the nasal sinus endoscope under general anesthesia. Drug treatment is ineffective, but if it is atrophic rhinitis, the nasal cavity is usually washed with physiological seawater, and vitamin AD drops are used externally to the nasal cavity.
