Should We Say Rhinosinusitis or Sinusitis?

Rhinosinusitis is preferred over sinusitis because inflammation of the sinuses usually occurs with the inflammation of the nasal mucosa.

    Rhinosinusitis Types

    Here are the types of rhinosinusitis, based on the duration of the symptoms:

    • Acute rhinosinusitis – < 4 weeks
    • Subacute rhinosinusitis – 4 to 12 weeks
    • Chronic rhinosinusitis – > 12 weeks
    • Recurrent acute rhinosinusitis – Four or more ARS episodes in a year per year, with interim symptom resolution.
