What is sinusitis?

Sinusitis  or rhinosinusitis is an inflammation or infection of the sinuses and nasal passages. There are a number of types of sinusitis including  acute, subacute and chronic sinusitis. Acute sinusitis can be triggered by a viral or bacterial infection; subacute or chronic sinusitis occurs as a result of allergies, problems in the structure of the nasal passages or various other environmental triggers.


How can it be treated?

Depending on the severity and type of infection, sinusitis may be treated with medication like antibiotics or nasal sprays. Sinus surgery may be recommended in certain situations where medication does not resolve the problem. Surgery involves opening up the natural drainage pathways of the sinuses that have been affected by infection or chronic disease. The surgery is minimally invasive and is performed using specialised cameras and equipment through the nose.
