Original Articles: Rhinitis, Sinusitis, and Upper Airway Disease

Rhinitis, sinusitis, and other upper airway diseases are common conditions affecting the nasal passages and sinuses, leading to symptoms like congestion, runny nose, sneezing, and facial pain. Rhinitis can be allergic, triggered by allergens such as pollen and dust mites, or non-allergic, caused by factors like infections or irritants. Sinusitis, an inflammation of the sinuses, often follows a cold or respiratory infection and can become chronic, lasting for months.
