Sinus Infection Overview

Sinus infection, or sinusitis, is an inflammation of the sinuses and nasal passages. A sinus infection can cause a headache or pressure in the eyes, nose, cheek area, or on one side of the head. A person with a sinus infection may also have a cough, a fever, bad breath, and nasal congestion with thick nasal secretions. Sinusitis is categorized as acute (sudden onset) or chronic (long term, the most common type).
Anatomy of the sinuses (also called paranasal sinuses): The human skull contains four major pairs of hollow air–filled–cavities called sinuses. These are connected to the space between the nostrils and the nasal passage. Sinuses help insulate the skull, reduce its weight, and allow the voice to resonate within it. The four major pairs of sinuses are the:
Frontal sinuses (in the forehead)
Maxillary sinuses (behind the cheek bones)
Ethmoid sinuses (between the eyes)
Sphenoid sinuses (behind the eyes)
The sinuses contain defenses against foreign bacteria (germs). If a disruption occurs that affects the normal host defenses inside the sinuses, those defenses may allow bacteria, which are normally present in the nasal passages, to enter any of the sinuses. Once there, the bacteria may stick to the lining cells and cause a sinus infection.
Acute sinusitis usually lasts less than eight weeks or occurs no more than three times per year with each episode lasting no longer than 10 days. Medications are usually effective against acute sinusitis. Successful treatment counteracts damage done to the mucous lining of the sinuses and surrounding bone of the skull.
Chronic sinusitis lasts longer than eight weeks or occurs more than four times per year with symptoms usually lasting more than 20 days.
The sinuses are covered with a mucus layer and cells that contain little hairs on their surfaces called cilia. These help trap and propel bacteria and pollutants outward. The ostiomeatal complex (OMC) connects the nasal passage to the paranasal sinuses.

Sinus Infection Causes

Acute sinusitis usually follows a viral infection in the upper respiratory tract, but allergens (allergy–causing substances), or pollutants may also trigger acute sinusitis. A viral infection causes damage to the cells of the sinus lining, which leads to inflammation. The lining thickens with fluid that obstructs the nasal passage. This passage connects to the sinuses. The obstruction disrupts the process that removes bacteria normally present in the nasal passages, and the bacteria begin to multiply and invade the lining of the sinus. This causes the symptoms of sinus infection. Allergens and pollutants produce a similar effect.
Bacteria that normally cause acute sinusitis are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. These microorganisms, along with Staphylococcus aureus and anaerobes (bacteria that live without oxygen), are involved in chronic sinusitis.
Fungi are also becoming an increasing cause of chronic sinusitis, especially in people with diseases that weaken the immune system, such as AIDS, leukemia, and diabetes.

Sinus Infection Treatment

Self–Care at Home

Home care can help open the sinuses and alleviate their dryness.
Promote drainage
Drink plenty of water and hydrating beverages. Hot tea is often recommended.
Inhale steam two to four times per day by leaning over a bowl of boiling hot water (not while the water is on the stove) or using a steam vaporizer with a towel over the head and bowl to prevent the escape of the steam. Inhale the steam for about 10 minutes. Taking a hot, steamy shower may also work. Mentholated preparations, such as Vicks Vapo–Rub, can be added to the water or vaporizer to aid in opening the passageways.
Thin the mucus: Expectorants are drugs that help to expel mucus from the lungs and respiratory passages. They help to thin mucous secretions, enhancing drainage from the sinuses. The most common is guaifenesin (contained in Robitussin, for example). Over–the–counter (OTC) liquid cough medications or prescription tablets can also combine decongestants and cough suppressants to reduce symptoms as well as to eliminate the need for the use of many medications. Read label ingredients to find the right combination of ingredients or ask the pharmacist for help.
Relieve pain: Pain medication such as ibuprofen (Motrin and Advil are examples), aspirin, and acetaminophen (Tylenol is in this category) can reduce pain and inflammation. These medications help to open the airways by reducing swelling.
