What is sinusitis and what causes it?
Sinusitis is an inflammation of the paranasal sinuses. The medical term is rhinosinusitis (“rhino-” meaning “nose”), because it affects the mucous membranes lining the nose and the sinuses.
The paranasal sinuses are part of the upper airways, and are connected to the nasal cavity. They are made up of several cavities in the skull found from the forehead down to the teeth of the upper jaw. Depending on where they are, these cavities are known as the frontal sinuses, the sphenoid sinus, the ethmoid cells and the maxillary sinuses. Sinusitis mostly affects the maxillary sinuses. The paranasal sinuses are lined with mucous membranes that have tiny hairs on them (ciliated epithelium). These mucous membranes produce a secretion that runs down through the nostrils.
What are the symptoms of sinusitis and what consequences can it have?
Sinusitis is an infection that is often associated with the following typical symptoms:
- stuffed-up nose
- the build-up of pus
If someone has sinusitis, their nose becomes stuffed-up due to the swelling and build-up of secretions. This makes it more difficult for them to breathe through their nose, which feels stuffy. The yellowish or greenish colour of the discharge is a sign of disease-causing germs.
Sinusitis often causes pain in the forehead, the jaw and around the eyes and less commonly toothache. The pain usually gets worse if you lean forward, for example when getting up out of bed. Sense of smell is often impaired or may even disappear completely. Many people also feel pressure in their face.
