  Description
Sinusitis, also called rhinosinusitis, is the inflammation of the lining of the sinuses (the nasal passage).

Depending of the sinus cavity affected, sinusitis is classified as:

- Maxillary, affecting the cheek and sometimes the teeth;
- Frontal, causing headache in the forehead;
- Sphenoidal, that may cause discomfort in the back of the head; and
- Ethmoidal, which can also cause headache above the eyes.

Most causes are due to microorganisms (mainly viral but also bacterial or fungus) or autoimmune disorders. However, anatomical abnormalities may represent an important factor to develop the condition.

Headaches in the forehead and blocked or runny nose are the main symptoms of sinusitis. Bacterial sinusitis usually produces fever, facial pain and swelling and last longer than viral sinusitis.
