What is sinusitis?

Sinusitis – also known as rhinosinusitis – is when the paranasal sinuses become inflamed, according to the National Institutes of Health (NIH). It is caused by an infection from bacteria, fungus, or a virus.

Healthy sinuses are able to drain out, allowing air to flow through them, according to the NIH. They contain no bacteria or germs.

When the openings of the sinuses become blocked or mucus builds up, it allows germs and bacteria to grow, according to the NIH.
