- What Are the Causes and Reasons for Sinusitis?

- quit. But I still don't understand the causes and reasons for sinusitis.
- Please explain?

- ANSWER: Sinusitis is an inflammation of one or more of the paranasal sinuses.
- The paranasal sinuses are cavities in the skull connected with the nasal
- passages. They are arranged in four pairs with members of each pair on the
- right and left side of the head. Doctors are not 100% sure of the functions
- of the sinuses. They are thought to help the nose to circulate, warm and
- moisten air as it is inhaled. Therefore, the lungs do not get a shock as cold
- or dry air is inhaled. The sinuses also play a minor role in voice
- production, as they are believed to act as resonating chambers.
- Sinusitis often occurs during an upper respiratory infection. Sometimes
- excessive or strong nose blowing may cause the infection to spread from the
- nose to the sinuses.
- There are, however, many, many other causes of sinusitis, which is why it
- is such a tricky, annoying problem.
- Some of the factors which trigger sinus troubles are allergies,
- infectious diseases, such as pneumonia or the measles, air pollution, diving
- and underwater swimming, sudden extreme changes of temperature, structural
- defects of the nose, or a complication from a tooth infection. When you have
- a sinusitis flare-up, you may feel pressure on the sinus walls, which in turn
- causes discomfort, pain, fever, and difficulty with breathing. This happens
- because the mucous membranes of the sinus are inflamed, and the openings of
- the sinus cavities become partially or fully blocked. The blockage often
- causes headaches and may lead to nasal discharge. Sinus sufferers also
- complain of dizziness, weakness and general discomfort. People suffering from
- these symptoms should certainly seek a doctor's help. A physician can use
- many diagnostic tools to confirm sinusitis, including radiography, ultrasound,
- multiple x-ray exposures, and computed tomography.
- Most cases of acute sinusitis will respond to antibiotics. The most
- commonly prescribed being ampicillin, amoxicillin, cefaclor,
- trimethoprim-sulfamethoxazole, and erythromycin. If this treatment is
- unsuccessful, your doctor should do further testing with x-rays to determine
- whether your case of sinusitis is infectious, allergic, or caused by another
- factor.
- Decongestants may also help the sinusitis patient by helping to increase
- drainage. Discomfort can be relieved through inhalation of steam or warm
- moist air.
- If you've been suffering with sinus problems for a long period of time,
- you may be one of those unfortunate people with chronic sinusitis. This
- condition occurs when the mucous membranes in the sinuses thicken and normal
- drainage becomes obstructed. If the previously mentioned treatments don't
- clear up the problem, surgery may be necessary.
- Since the sinuses are close to the ears and brain, it is important to
- treat sinusitis aggressively to minimize the risk of spreading the infection
- to those organs.
