Chronic rhinitis can be clinically divided into chronic simple rhinitis, chronic hypertrophic rhinitis, and chronic allergic rhinitis, which are the most common types seen in clinical practice. Chronic simple rhinitis is often seen in children and generally occurs due to repeated acute rhinitis attacks or prolonged unresolved symptoms. Chronic hypertrophic rhinitis results from repeated simple rhinitis, causing bilateral turbinate mucosal diffuse congestion and hyperplasia with poor shrinkage effects. Chronic allergic rhinitis is caused by inhalation of certain allergens into the nasal cavity due to weakened immunity and resistance, leading to symptoms such as nasal congestion, runny nose, and sneezing. In terms of treatment, simple rhinitis can be effectively managed with medication. Chronic hypertrophic rhinitis may require partial turbinectomy of both sides for cure, while allergic rhinitis can be gradually improved by enhancing immunity and resistance.
