Are there different types of sinusitis?

Sinusitis is classified as either acute or chronic. Acute sinusitis usually comes after a viral infection, such as a cold or the flu, with the symptoms lasting less than 4 weeks. In most cases, chronic sinusitis follows acute sinusitis; its symptoms can last 12 weeks or more. However, it can also be caused by other factors, such as an infected tooth, growths inside the nasal cavity (nasal polyps), damage to the nose or face, or an allergy such as hay fever.
