What causes acute bacterial rhinosinusitis? ABRS is caused by bacteria that infect the lining of your nasal cavity and sinuses. It’s most often caused by the bacteria Streptococcus pneumonia. Or it may be caused by the bacteria Haemophilus influenzae.

How do you get chronic rhinosinusitis?

Chronic sinusitis can be caused by an infection, growths in the sinuses (nasal polyps) or swelling of the lining of your sinuses. Signs and symptoms may include a blocked or stuffy (congested) nose that causes difficulty breathing through your nose, and pain and swelling around your eyes, cheeks, nose or forehead.

Is sinusitis and rhinosinusitis the same?

Acute rhinosinusitis (ARS) is defined as symptomatic inflammation of the nasal cavity and paranasal sinuses (figure 1) lasting less than four weeks. The term “rhinosinusitis” is preferred to “sinusitis” since inflammation of the sinuses rarely occurs without concurrent inflammation of the nasal mucosa [1].
