Sinus infections may cause pain in the face, teeth, or head.
Sinus infections are usually caused by a viral infection is simple.
Bacterial infections of the sinuses is suspected when there is pain facial, nasal discharge like pus, and symptoms persist for more than a week and did not respond to nasal drug over-the-counter.
Bacterial sinusitis is usually treated with antibiotic therapy.
Allergic sinusitis treatment early can prevent secondary bacterial sinus infection.

What causes sinusitis?

Sinusitis can occur when there is a disturbance of the air flow and to the sinus cavity and disruption of mucus discharge. The presence of fever, flu, allergies and irritants material can cause swelling of the ostia so that the drainage holes become clogged and disrupt the flow of air sinuses and mucous discharge. Another cause of hopelessness ostia are tumors and trauma. Mucous fluid drainage out of the sinus cavities can also be hampered by the thickening of the mucus fluid itself. Coagulation is due to award of antihistamine drugs, fibro cystic disease, and others. Mucus-producing cells have tiny hairs (cilia) that always moves to push fluid out of the sinus cavity mucus. Cigarette smoke is the culprit of the destruction of this fine hair that becomes impaired mucus discharge. Fluid accumulated mucus in the sinus cavity in the long term is a convenient place for the life of bacteria, viruses and fungi.

What are the types of sinusitis?

Sinusitis can be divided into two major types, namely based on the duration of illness (acute, subacute, chronic) and based on the type of inflammation (infectious and non-infectious). Acute sinusitis is called when a disease duration of less than 30 days. Subacute sinusitis when disease duration between 1 month to 3 months, whereas chronic sinusitis when the disease affects more than 3 months. Sinusitis is usually caused by a viral infection although in some cases some are caused by bacteria. While most non-infectious sinusitis caused by allergies and irritation of chemical substances. Subacute and chronic sinusitis is often a continuation of acute sinusitis who do not get adequate treatment.

How to treat sinusitis?

For sinusitis is caused by a virus, antibiotics are not necessary. Drugs commonly prescribed for viral sinusitis is pain relievers such as paracetamol and decongestants. Suspect there has been a sinusitis infection by bacteria if there is any facial pain, purulent nasal mucus, and symptoms occur more than a week. Sinusitis is a bacterial infection is generally treated using antibiotics. The selection of antibiotics based on the type of bacteria that most commonly affects the sinuses due to get antibiotics that really fit should wait for the results of bacteria culture that takes a long time. The five most common types of bacteria that infect the sinuses are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, and Streptococcus pyogenes. Antibiotics chosen should be able to kill five kinds of bacteria. Some options include antiobiotika amoxicillin, cefaclor, azithromycin, and cotrimoxazole. If there is no improvement within five days then it should be considered to give amoxicillin plus clavulanic acid. Antibiotics are recommended at least 10 to 14 days. Administration of decongestants and mucolytics can help to smooth drainage of fluid mucus. In the case of the chronic cases, can be considered perform fluid drainage of mucus by means of surgery.
