Sinusitis is present when the tissue lining the sinuses become swollen or inflamed. It occurs as the result of an inflammatory reaction or an infection from a virus, bacteria, or fungus.
🔥 Causes
The sinuses are air-filled spaces in the skull. They are located behind the forehead, nasal bones, cheeks, and eyes. Healthy sinuses contain no bacteria or other germs. Most of the time, mucus is able to drain out and air is able to flow through the sinuses
When the sinus openings become blocked or too much mucus builds up, bacteria and other germs can grow more easily.
🔥 Sinusitis can occur from one of these conditions:
- Small hairs (cilia) in the sinuses fail to properly move mucus out. This may be due to some medical conditions.
- Colds and allergies may cause too much mucus to be made or block the opening of the sinuses.
- A deviated nasal septum, nasal bone spur, or nasal polyps may block the opening of the sinuses.
- Chronic infection can cause mucosal swelling and inflammation.
🔥 There are three types of sinusitis:
- Acute sinusitis is when symptoms are present for 4 weeks or less. It is caused by bacteria growing in the sinuses.
- Chronic sinusitis is when the symptoms and swelling of the sinuses is present for longer than 3 months. It may be caused by bacteria or a fungus.
- Subacute sinusitis is when the symptoms and swelling is present from 1 to 3 months.
