Acute sinusitis is generally ascribed to the bacterial infection. Most of the patients suffering from colds have mild sinus inflammation that last for a short period. A few patients with colds may develop typical sinusitis conditions. Flu and colds may create nasal congestion and inflammation, obstructing the sinuses and creating an environment conducive for bacterial growth. Thus, symptoms of sinus infection develop.
Causes for Recurrent or Chronic Sinusitis Conditions
Acute sinusitis that was not treated in time may damage mucus membranes and cause recurrent or chronic infection.
During some chronic disorders, such as Wegener's granulomatosis, Kartagener's syndrome, cystic fibrosis, hypothyroidism, immune system related diseases, AIDS and diabetes, airways may swell or thick stagnant mucus may occur continuously. These ailments may also cause chronic sinusitis.
Structural abnormalities may block the nasal passage, causing chronic sinusitis conditions. Common abnormalities include small benign structures (polyps) in the nasal passage. Polyps obstruct air and mucus flow. Polyps may result due to previous untreated sinusitis. Enlarged adenoids may cause sinusitis. Adenoid is a mass of lymphatic tissue on the pharynx’s posterior wall. Other structural abnormalities include cleft palate, deviated septum, nasal bone spur and tumors.
Allergic reaction to fungus may also create symptoms of sinus infection. Alternaria, Aspergillus, Bipolaris and Curvularia fungi trigger sinusitis. However, fungi are not common cause for sinusitis. Fungi may colonize sinuses of chronic sinusitis patients. These patients may need anti-fungal treatment.
Some chronic sinusitis may occur due to continuous inflammation instead of presence of bacteria.
Bacteria play a direct or an indirect role in chronic sinusitis, but, in some cases, bacteria may not play any part at all. They may thrive in the sinuses but do not cause the infection. This condition is referred to as colonization. Moraxella catarrhalis causes sinusitis in children. H. influenzae and Streptococcus pneumoniae bacteria trigger sinusitis in both children and adult.
Airborne chemicals, irritants and other pollutants cause symptoms of sinus infection.
A weak immune system may also lead to sinusitis.
Malfunctioning sinus cilia may result in sinusitis. Malfunctioning could be because of medical disorders.
Allergies and colds may increase the mucus that may obstruct sinus opening.
Infected teeth may infect sinuses.
During cystic fibrosis, a genetic disorder, sticky thick mucus gathers within the body. As a result, patients become prone to infections.

Doctors may perform a complete physical examination and medical history review to diagnose symptoms of sinus infections. Other scientific diagnostic methods may also be used. For instance, x-ray, computerized tomography (CT), ultrasound and cultures.
X-ray uses invisible electromagnetic energy beams to capture images of internal bones, organs and tissues. Quality and accuracy of x-ray depends on doctors’ ability and technique to read the images correctly. In many cases, x-ray of sinuses does not capture symptoms of sinus infections.
CAT or CT scan, a noninvasive reliable medical test,uses computer technology and X-rays to generate multiple vertical and horizontal slices (cross-sectional images) of affected body part. It generates real time pictures. These scans reveal more details of the body as compared to the X-rays. The facial CT scan produces pictures of paranasal sinus cavities. Sinus CT is performed to identify inflammatory diseases, gather anatomical information for sinus surgery to remove tumors in sinuses or nasal cavities, and identify sinuses filled with fluid and thick sinus membranes. CT is an easily available service requiring lesser time than magnetic resonance imaging (MRI). This cost-effective, accurate and painless method can capture pictures of blood vessels, soft tissues and bones simultaneously. Quick and simple CT scans are a good choice for emergency cases.
Ultrasound, a noninvasive tool, is also used to identify symptoms of sinus infections. The tool is reliable, quick and less costly than a CT scan. However, results of ultrasound are not as good as that of the CT scan. Ultrasound is generally not used for sinusitis diagnosis.
Cultures of sinus or nose fluid are prepared in the laboratory to help in diagnosis.
Doctors may also conduct blood tests.
Physicians may recommend a visit to an ear, nose and throat (ENT) specialist if sinusitis recurrent and severe. The specialist may conduct more tests. ENT specialists use nasopharyngoscope, a flexible fiberoptic tube, to examine the passage into the sinuses (OMC) and the nasal passages. The tube inserted in the nose helps in visualizing structural deformities like tonsils, enlarged adenoids, nasal polyps and deviated nasal septum. The specialist may drain the sinus to examine the organisms. Sinus draining is an invasive procedure. It requires a needle, which is inserted into the sinus through gum or skin to extract the fluid. The fluid is sent to the laboratory for culture preparation and identify bacteria. However, it is uncommon because of high level of discomfort.
