The Paranasal sinuses are a group of four paired air filled cavities in the front of the skull that surround the nasal cavity and are named after the bones of the face near which they are located.
Maxillary sinuses, are the largest of the group and are situated under the eyes, in the maxillary bones of the skull.
Frontal sinuses, are situated above the eyes, in the frontal bone which forms the front of the forehead.
Ethmoid sinuses, a smaller group in the ethmoid bone between the eyes and nose.
Sphenoid sinuses, are located in the spend bone at the centre of the scull under the pituitary gland.
All of the paranasal sinuses are lined with mucus and tiny hairs called cilia and are joined to the nasal cavity via small openings called ostia.
When we get a nasal infection or allergic reaction, these sinus linings can become swollen and inflamed. The tiny hairs are no longer able to waft the mucus into the nasal cavity, causing it to back up and create pressure.
To compound the problem, the lymphatic glands will have released extra white blood cells and fluid to deal with any infection or allergen.
Problems from blocked sinus and associated swollen tissue may result in headaches, sore throat, earache and facial nerve pain (Trigeminal neuralgia).
In some cases, repeatedly suffering from colds can be a sign that the lymphatic system of the head is not working correctly.
The paranasal sinus may also suffer from inherited problems or be damaged due to injury, surgery or dental problems.
Specific lymphatic drainage techniques combined with trigger point therapy can help relieve many of these symptoms and stimulate the normal lymphatic flow.
Please note that sinus lymphatic drainage massage can not be carried out when untreated infection is present.
