Sinusitis

Definition: Inflammation and infection of one or more paranasal sinuses caused by bacteria or viruses. But what are the paranasal sinuses 

The paranasal sinuses are actually "holes" that exist in the bones that form the base of the nose and these cavities have inlet and outlet located in our nasopharyngeal secretion, or nasal cavity. These bones are: maxillary, frontal, ethmoid and sphenoid.


See the figure below:

And how infection occurs in some breasts? 



As they produce the secretion and ha an output and an input for the same, it's just that something or something obstructs the output to produce a secretion accumulation and bacterial growth in the sinuses.


The main cause of sinusitis is a cold, rather, we will develop a framework for sinusitis usually after a cold box or a box of nasopharyngeal obstruction.

Note sinus drainage hole inside the nose. Since these outputs are "closed" accumulation of secretions in the sinuses and bacterial proliferation occurs later! 






Sinus formation: 


The child was born with rudimentary ethmoid and maxillary sinuses, but they are displayed in a rx review to 4 years. The sphenoid appears on the front and 5 years to 7 years sinuses. 

Important - you mom - 7 years before not to insist on control rx doctor about whether or not he has sinusitis, since almost nothing appears on the exam. The diagnosis is clinical, the conversation between the mother and the doctor and the patient examination and nothing else!

Training sinus age. 

Causes of sinusitis and predisposing factors: 

1 - Viral: resolves spontaneously with the flu. 

2 - Bacterial: a complication and infection by bacteria or more sinuses, requiring treatment with antibiotics. The main bacteria that cause sinusitis are Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. 

As indicated above, we develop a framework for sinusitis, we have something or something that prevents the release of the secretion of the sinuses and the main causes of obstruction are:

Cold as the main cause; 

Allergic rhinitis; 

Exposure to tobacco smoke; 

Gastroesophageal reflux disease; 

Abnormalities of the anatomy of the nose and deviated septum, nasal polyps, enlarged adenoids and foreign body in the nose;

Notice the more opaque than the sinus maxillary sinus maxillary left right (white). 

treatment 

Treatment should be done with antibiotics and our choice is the famous amoxicillin and effective treatment should be used for 14 to 21 days. 

In the case of treatment failure, other antibiotics can be used as the class of macrolides (azithromycin and clarithromycin) or think of the combination of amoxicillin and clavulanic acid.

There are complications of sinusitis 

Of course, due to the proximity of the sinus structures skull, very important in our life. 

A dreaded complication is caused periorbital cellulitis-ethmoid-inflammation of the subcutaneous tissue around the eye and can lead to orbital cellulitis that besides inflammation can cause proptosis of the eye and even paralysis. 

And other less common as meningitis and brain abscess. 



Conclusion and end of the text: 



My intention in this article is to clarify the pathophysiology of sinusitis, ie, it desnvolve therefore a person who presented a clinical picture of this kind and treated more have the disease. 


Bottom line: You do not have sinusitis, you are sinusitis. Just treat!
