What Tests Diagnose The Cause Of Sinus Infections And Sinusitis
Sinus infection is most often diagnosed based on the history and examination of a doctor. Because plain X-ray studies of the sinuses may be misleading and procedures such as CT and MRI scans, which are much more sensitive in their ability to diagnose a sinus infection, are so expensive and not available in most doctors’ offices, most sinus infections are initially diagnosed and treated based on clinical findings on examination. These physical findings may include:
- redness and swelling of the nasal passages,
- purulent drainage from the nasal passages ,
- tenderness to percussion over the cheeks or forehead region of the sinuses, and
- swelling about the eyes and cheeks.
Occasionally, nasal secretions are examined for secreted cells that may help differentiate between infectious and allergic sinusitis. Infectious sinusitis may show specialized cells of infection while allergic sinusitis may show specialized white blood cells of allergy . Physicians prescribe antibiotics if the bacterial infection is suspected. Antibiotics are not effective against viral infections many physicians then treat the symptoms.
In addition, both rigid and flexible endoscopy has been used to obtain diagnostic material from sinuses. These procedures are usually done by an otolaryngologist under topical and local anesthesia. Occasionally, there may be a need to sedate the patient. Some investigators suggest that endoscopy specimens are comparable to those obtained by needle puncture.
Doctors Say It’s Ok To Wait Before Treating Kids’ Sinus Infections
Sinusitis gets diagnosed 30 million times a year, and with the infections accounting for 20 percent of all antibiotic prescriptions, the ENTs see this as a chance to reduce overprescribing.
They’re going further than their previous guidelines in saying that even if you’re really sick, it’s OK to wait on the meds. And they’re breaking ranks with their fellow physicians in infectious disease and internal medicine, who say everyone with a bacterial infection should get an antibiotic.
“We’re not saying you’re wrong to do it,” Rosenfeld says. “We’re saying, you know, there’s a good chance you’re going to get better on your own.”
So then what to do while you’re feeling like your head is going to explode?
Saline nose washes get a big thumbs up from the ENTs, as do as over-the-counter pain medications. The saline washes out mucus and reduces stuffiness, and also improves the health of membranes, Rosenfeld says.
Steroid nose sprays may help with inflammation, the guidelines say, especially for people with chronic sinusitis, which lasts more than three months.
Chronic sinusitis shouldn’t be diagnosed just on symptoms, the guidelines say a doctor needs to document there’s inflammation of the nose and sinuses, something that can be done by looking up the nose with various scopes.
“You can diagnose acute sinusitis from your armchair at home,” Rosenfeld says. “But you can’t diagnose chronic sinusitis.” For that, at least, you need that doctor.

But the Food and Drug Administration cautions against such advice, particularly for at-home tests.
“The FDA advises that COVID-19 tests should be used as authorized, including following their instructions for use regarding obtaining the sample for testing,” the agency said in a statement provided to NBC 5 Wednesday.
The FDA warned, however, of potential safety concerns for self-collection of throat swabs “as they are more complicated than nasal swabs – and if used incorrectly, can cause harm to the patient.” The agency added that the Centers for Disease Control and Prevention recommends throat swabs be collected by a trained health care provider.
According to the FDA’s testing guidance, which was last updated in December, “different tests are authorized to be used with different types of samples,” but the most common sample types include nose or throat swabs and saliva samples.
Dr. Michael Daignault, an ER physician and Chief Medical Advisor for Reliant Health Services, told NBC 5 Tuesday he has seen “some cases where people who do the regular nasal swab test negative.”
“But then I’ve had some doctor friends who started swabbing the backs of throats, and they’re finding that’s positive,” he said.
Some doctors, including Dr. Anthony Fauci, White House chief medical advisor and the top U.S. infectious disease expert, have cautioned that not all at-home antigen tests may be able to adequately detect the omicron variant.

Types Of Chronic Sinusitis Or Chronic Sinus Infections
While acute sinusitis often involves an infection, chronic sinusitis does not. Sometimes, the long-term illness is caused by an infection that hasn’t cleared up properly, but most often the exact cause of chronic sinusitis isn’t known.
But clinicians may categorize chronic sinusitis into one of three types depending on the features present.
The most common type of the illness, chronic sinusitis without nasal polyposis, involves swelling and inflammation of the mucous membranes by various non-polyp factors, such as allergies or irritation and infections.
Chronic sinusitis with nasal polyposis, on the other hand, involves nasal polyps that are large enough to clog the sinus. It’s not always clear why some people develop these polyps and others dont.
In chronic sinusitis with fungal allergy, people experience a strong allergic reaction to fungi in the air, which causes their mucous membranes to produce a thick, dense mucus.
Research And Statistics: Who Gets Sinus Infections
Each year, acute sinusitis affects about 31 million Americans, who spend a whopping $1 billion on over-the-counter medications and $150 million on prescription medications to treat the illness, according to the American College of Allergy, Asthma, & Immunology.
Epidemiologic studies suggest 5 to 12 percent of people have chronic sinus infections. However, research published in December 2018 in The Journal of Allergy and Clinical Immunology suggests this may be an overestimation due to misdiagnosis. According to the study, which relied on imaging tests for diagnosis , about 3.0 to 6.4 percent of people may have chronic sinus infections. 32786-6/fulltext” rel=”nofollow”> 5)

Make sure you dispose of the tissue and then clean your hands with soap and water or an antimicrobial sanitizer.
How Do Doctors Treat Sinus Infections
One the diagnosis is made, the typical treatment for sinus infection is antibiotics to clear up the bacteria causing the sinus infection. Although, the overuse of antibiotics is a cause for concern, so many doctors will prescribe these medications if your symptoms extend beyond seven to 10 days.
Your doctor may also prescribe a topical nasal corticosteroid to reverse the swelling in the sinuses. Finally, over-the-counter medications to help you cope with the daily symptoms of a sinus infection while the medications begin to do their work.
Some of the typical over-the-counter symptom relievers include:
- Antihistamines can block the inflammation that swells your sinus passages
- Nasal decongestant sprays can be used on a limited basis
- Nasal saline washes can clear out heavy mucus
- Topical nasal corticosteroids

Causes And Risk Factors Of Sinus Infection
The terms “sinus infection” and “sinusitis” are often used interchangeably, but sinusitis simply refers to the inflammation of the sinuses, with or without an infection. The medical term for sinusitis is rhinosinusitis because the illness affects the mucous membranes in both the sinuses and nose.
Sinus infections ultimately develop because of sinus and nasal blockages that result in sinus inflammation. There are several underlying causes of sinus blockage, including various environmental, anatomical, and genetic factors. But the most common cause of the blockage is inflammation or swelling of the nasal passages because of the common cold or allergies.
In healthy people, mucosal secretions are always moving and draining into the nasal cavity. But
when blockage occurs, mucus fails to drain properly, increases in thickness, and fills the sinus spaces.
The cilia also slow down their sweeping and cleaning, making it even harder for mucus to drain.
When the mucus is unable to drain, it becomes the perfect medium for microbes to grow out of control and cause an infection.
When To See A Doctor About A Sinus Infection
On the other hand, a secondary acute bacterial infection may develop, so it’s advised that you see a doctor if your symptoms last more than 10 days or if your symptoms initially improve but then worsen again within the first 7 days.
See a doctor immediately if you experience:
- A persistent fever higher than 102 degrees F
- Changes in vision, including double vision
- Symptoms that are not relieved with over-the-counter medicines
- Multiple infections within the past year
- Sudden, severe pain in the face or head
- Confusion
- Swelling or redness around the eyes
- Stiff neck
