Testing Procedures For Detecting Sinusitis
The sinuses are the interconnected network of small, hollow cavities present in the skull region that aid in humidification of the air inhaled and helps in enhancing our voices. The sinuses help in producing mucus that aid in keeping the nasal passages free of allergens and impurities.
Sinusitis is the irritation and swelling to the tissue lining these cavities. In certain situations, this inflammation is known to obstruct the sinuses, holding in mucus and air within them. This could lead to pain, discomfort and undue pressure, at times leading to a bacterial infection. There are two main forms of sinusitis namely acute and chronic. Initially the swelling is offset due to cold or allergy or due to poor immunity.
There are a host of tests undertaken to detect any problems in the sinus. They include:
A Physical exam: During the examination procedure, the doctor examines the interior of the nose with the aid of an illuminated viewer to have a look at the ridges within the nose known as turbinates that aid in humidifying and filtering the air. Any kind of swelling in the turbinates is accurately diagnosed. During the examination the face is tapped or pressed over the area f the sinuses to detect any kind of pain.
A CT scan: Also known as computed tomography or CT scanner employs the use of X-rays and computer to produce meticulous comprehensive images of the sinuses. The CT scanning procedure helps detect chronic sinusitis.
MRI scan: The Magnetic resonance imaging or MRI scan uses magnetic waves to form explicit images of the sinuses. The CT and MRI scanning procedures could be employed in unison.
Rhinoscopy: Rhinoscopy or Endoscopy makes use of an endoscope – a bendable tube attached with a camera on one of its ends. The doctor inspects the interiors of the nose and the sinuses using the endoscope.
Sinus cultures: A procedure carried out with the assistance of a needle or during the course of endoscopy is done to extract a sample of the mucus from the interiors of the sinuses.
Skin Testing: The skin is tested for presence of several forms of allergens that could aid in establishing whether allergies are responsible for the sinusitis.
X-Rays: A simple X-ray would help to decipher any problems associated with the bones located in the region of the sinuses. A CT scanning is considered to give better-quality images than compared to the simple X-ray films.
