Sinusitis is a disease caused by blockage of the sinus canals as a result of infection.

What is sinus?

The sinus is the air space around the nose and in the forehead, inside the bones. There are four pairs of sinuses symmetrically in the head region. These are Frontal, Ethmoid, Sphenoid and Maxillary sinuses. Sinuses are connected to the nasal cavity via channels (ostium).

What Do Sinuses Do?

The sinuses act as an air cushion in case of head blows. They also resonate the sound. Thanks to the air gaps, they lighten the head. The sinuses continuously produce a transparent fluid (mucus), which flows through the sinus canals into the nasal cavity, then drains back into the throat and is swallowed, reaching the stomach.Mucus moisturizes inhaled air. Bacteria, germs and viruses in the nasal cavity reach the stomach thanks to the mucus produced in the sinuses and are destroyed by the stomach acid.Apart from these known benefits, modern medicine has not been able to determine exactly what other functions the sinuses perform.

How Does Sinusitis Occur?

In general, sinusitis disease manifests itself in the form of pain in the parts where sinuses are due to the filling of the sinuses and the pressure caused by the blockage of the sinus canals that drain the mucus produced in the sinuses. There are three main factors that cause sinusitis. Blockage of the nasal discharge channels of the sinuses. Change in mucus content or consistency. Disruption of the system that actively carries mucus within the sinuses to the sinus canals. One or more of these factors can be seen at the same time.

What are the Types of Sinusitis?

Sinusitis is generally classified as follows: Acute sinusitis, chronic sinusitis, subacute sinusitis, recurrent sinusitis, parazanal sinusitis, fungal sinusitis, bacterial sinusitis. In addition to all these types, there may be combinations of available sinusitis types.
