SINUSITIS
The air passages of the nose, sinuses and lungs are all
lined with a mucous membrane. This has a rich blood supply
which enables it to warm and moisten the breathed in air.
A thin film of mucous covers the whole of the airways and
is kept constantly moving upwards away from the lungs by
the sweeping action of the minute hair-like structures in
the membrane. This forms a most effective filter for removing
particles of dust from the air before it reaches the lungs.
The irregularity of the nasal cavity and the air sinuses
which open into it increase the area of mucous membrane the
air comes into contact with making the warming and filtering
more efficient.
Swelling of the mucous membrane readily obstructs
drainage of secretions from the sinuses and may cause sinusitis.
The sinuses are like little caves with an opening halfway
up the wall to let the secretions out. The mucous membrane
lines the cave but if it becomes inflamed it restricts
the opening and at the same time produces more mucous. This
causes
a build up of pressure which leads to pain. Acute sinusitis
is usually caused by a virus and the patient may have a
fever, a headache, and pain in the face with localised tenderness
over the forehead or cheekbones. After a few days bacteria
start to colonise the damp warm mucous in the sinuses and
a secondary bacterial infection occurs producing a thick
discoloured nasal discharge - catarrh. If the body is unable
to combat the infection and reduce the swelling in the
mucous
membrane the condition drags on and the patient may have
problems with catarrh for several days, weeks or even months.
TREATMENT
Treatment with inhalations may help to improve the drainage
of the sinuses. Treatment with Manual
Lymph Drainage and Connective Tissue
Manipulation helps by improving the circulation and reducing
the inflammation and congestion in the mucous membranes thus
allowing the mucous to drain out of the sinuses and combat
the infection.
