Which of the following can contribute to rhinosinusitis?

• A. Allergies
• B. Pollutants
• C. Dehydration
• D. Genetics

Answer: (B)

Pollutants can significantly contribute to rhinosinusitis by causing irritation and inflammation in the nasal passages and sinuses. When individuals are exposed to environmental pollutants, such as smoke, exhaust fumes, or industrial chemicals, these irritants can trigger an inflammatory response in the mucous membranes lining the sinuses. This inflammation can lead to swelling, blockage of sinus drainage pathways, and the retention of mucus, creating a conducive environment for infections and further exacerbating symptoms of rhinosinusitis.

In contrast, while allergies and dehydration can also have an impact on the sinuses, pollutants are a direct environmental factor that compromises the mucosal barriers and promotes sinusitis more acutely. Genetics may play a role in a person's predisposition to certain conditions, but it doesn't directly contribute to the development of rhinosinusitis in the same way environmental factors do.
