Sinusitis - is infectious and inflammatory process,
localized in the sinuses or paranasal sinuses. Doctors distinguish between two
the type of the disease: acute sinusitis (characterized by hyperemia
serous, purulent and then lasts generally 2-3 weeks) and
chronic sinusitis (usually occurs as a result of repeatedly
repetitive and poorly healed acute sinusitis).
What are sinuses?
The sinuses - four pairs of air cavities, which are located inside the head,
around the nose. Yet they are called paranasal cavity or paranasal
sinus. Types of sines:
- sinusitis - inflammation of the mucosa of the maxillary (maxillary) sinuses;
- sinusitis - inflammation of the frontal sinus;
- ethmoiditis - inflammation of the ethmoidal labyrinth;
- sphenoiditis - inflammation of the sphenoid sinus.
sinus opens into the nasal cavity to the free passage of air and
mucus, so any infection, immune or allergic reaction to
nasal cavity and sinuses also captures. When air is inflammation in the sinus
along with pus or other discharge, it puts pressure on the wall
sine and causes pain. Also, if the inflamed sinus membrane
prevents air from entering inside the cavity in a vacuum,
causing painful effect.
What are the symptoms of sinusitis
Location of pain depends on which of the sinuses by inflammation covered. Characteristic symptoms of sinusitis include:
- headache, particularly severe in the morning;
- mucous or purulent discharge from the nose;
- pain in the upper jaw, toothache, pain with pressure on the cheek at an inflammation of maxillary sinus (sinusitis);
ethmoidal sinuses (ethmoiditis) causes swelling and soft tissue swelling
around the eyes, eyelids, pain between the eyes. nose wings are
sensitive to the slightest touch, there is a partial loss
smell and nasal congestion;
- in inflammation of the frontal sinuses
(Front), the leading symptoms are severe headaches,
mainly in the forehead and a feeling of heaviness in the affected projection
- sinus infection wedge (sphenoiditis) found
relatively rare and occur ear pain, pain in the neck,
pain "at the top" of the head.
Other symptoms of sinusitis are similar
with those for colds, namely increased
fever, weakness, fatigue, night cough, nasal congestion and

Causes of acute sinusitis
common cause of causing acute sinusitis is
respiratory viral infection or, simply put, the common cold.
Viruses can penetrate into the sinuses, causing their inflammation. For example,
in contact with viruses or bacteria in the nasal cavity of the body responsible

narrowing of the lumen of the nasal passages and shortness of breath. When
