What is Sinusitis?
Sinusitis is defined as an inflammation of the sinus lining commonly caused by bacterial, viral and / or microbial infection; as well as, structural issues such as ostial blockage. If the sinus opening becomes swollen shut, normal mucus drainage may accur, and this may lead to infection and inflammation of the sinuses
TYPES OF SINUSITIS
There are two main categories of sinusitis: acute and chronic.
Sinusitis is usually preceded by a cold, allergy attack or irritation from environmental pollutants. Often, the resulting symptoms, such as nasal pressure, nasal congestion, a “runny nose,” and fever, run their course in a few days. However, if symptoms persist, a bacterial infection or acute sinusitis may develop.
Most cases of sinusitis are acute (or sudden onset); however, if the condition occurs frequently or lasts 12 weeks or more, you may have chronic sinusitis.
When does acute sinusitis become chronic?
When you have frequent sinusitis or the infection lasts three months or more, it could be chronic sinusitis. Symptoms of chronic sinusitis may be less severe than those of acute; however, untreated chronic sinusitis can cause damage to the sinuses and cheekbones that sometimes requires surgery to repair.
