Acute rhinosinusitis (ARS) is a term that can be used to describe any short-lasting condition that causes inflammation of the lining of the nose and sinuses, but it is typically associated with short-lived symptoms that follow a common cold.
The word “chronic” in chronic rhinosinusitis means that the condition is long-term (a patient has had it for at least 12 weeks, or in some cases, even years) and may not always have a cure but symptoms can usually be well controlled. This distinguishes it from “acute rhinosinusitis”, which usually gets better within 2 to 3 weeks.
Chronic rhinosinusitis can be divided into categories. Some kinds of chronic rhinosinusitis cause the patient to develop nasal polyps (chronic rhinosinusitis with nasal polyps), and some kinds do not (chronic rhinosinusitis without nasal polyps). Nasal polyps are benign inflamed swellings which fill the sinuses and nasal cavity.
