Treating A Sinus Infection

SINUSITIS

The blockade of sinus drainage caused the series of changes that lead to chronic sinusitis. Chronic sinusitis often occurs as a result of repeated episodes or inadequately treated acute sinusitis.

Chronic sinusitis occurs when there are conditions that prevent the drainage of the sinuses, since the initial filling of the hole in one breast produces changes in the mucosa and the nasal cavity of the other. Bacterial contamination causes an acute infection that may progress in subacute or chronic phase with persistence of suppuration. The untreated infection prevent or impair ciliary function by interfering with drainage of pus from the sinus into the nose.

Sinusitis is acute or chronic inflammation of one or more of the sinus structures that accompany upper respiratory tract: frontal sinus, ethmoid, maxilla. The most severe complications include ocular-orbital, osteomyelitis, brain abscesses and meningitis.

It is inflammation that affects the lining of the sinuses. In general, microorganisms (bacteria) find the breasts through the holes, producing congestion, drainage and air resorption leads to pain at the respective breast. Sinusitis is usually classified as acute (less than three weeks) and chronic. Although rhinitis affect more children than adults, it is the latter that have most often due to complete development of cavities affected. The most common predisposing factors are: allergic rhinitis, nasal septal deviation, polyposis, etc.

Cavities are most affected the maxillary sinuses, which is likely to happen in a bilateral or isolated, whereas when it comes to the rest of the breasts (especially the ethmoid) participation is widespread. A common cause of sinus involvement corresponds to the inlet port thereof, for anatomical abnormalities, edema or polyposis, can reduce and block the drainage facilitating infection. Another mechanism not least, in this case to the maxillary sinuses, is the dental abscess or apical granuloma of the maxillary teeth, especially premolars, which invades the same through the thin bone that separates them and, even unable to communicate, at least temporarily, with the mouth after a tooth extraction. The most common symptoms leading to a set characterized by fever (especially in the acute forms), facial pain, the eye in the frontal sinus and in the molar region and upper teeth in the jaw and the center of the face in the ethmoid , nasal obstruction, foul-smelling discharge from the nostrils and the back of rhino pharynx, increased pain when pressing down the head and facial pain points, and also cough, etc. Microbial agents that predominate in the condition are S. pneumonia and H. influenzae. Antibiotic treatment for 7 to 10 days reduces the number of complications of this condition, which include orbital cellulitis, bone infection of the neighboring structures, abscesses in the brain and meninges and the dreaded septic cavernous sinus thrombosis.

Acute Sinusitis: an infection of one or more sinuses that can last from one day to three weeks and is characterized by pain in the affected sinuses, nasal congestion or obstruction, purulent nasal discharge and fever. The most common causative organism is Streptococcus pneumoniae.

Chronic sinusitis: a sinus infection that lasts less than three months being most common symptoms of congestion or obstruction, nasal discharge, facial pain and headache. The causal bacteria most commonly isolated is Staphylococcus aureus. They are also much more common in chronic sinusitis in acute infections caused by anaerobic organisms, Gram negative and many germs.

Each sinus is lined with ciliary epithelium synthesizes and directs mucus into the nasal cavity through the opening called the ostium. The movement of mucus within the sinuses is not dependent on gravity, in fact the holes in the maxillary and sphenoid sinuses are located on the top and pushes the mucus ciliary action in an upward direction opposite to the direction of gravity. Formerly it was thought that chronic sinusitis was caused an infection in one of the larger sinus chambers. This theory was based on findings from radiographs of the sinuses of patients showing opacification and / or mucous membrane thickening in the maxillary and frontal sinuses. It was felt that the ethmoid sinuses were not clearly on the radiographs were not involved in the disease process. Present the results of recent research lead to the conclusion that the ethmoid sinus is the most common and also may cause frontal and maxillary sinusitis.
