• Original Article • 21 August 2021 Does Degree of Nasal Septal Deviation Measured with CT PNS have a Role in Management of Deviated Nasal Septum? • • • • … • ORCID: orcid.org/0000-0001-6050-1534 Show authors Indian Journal of Otolaryngology and Head & Neck Surgery volume 74, pages 1665–1667 ( 2022) Deviated nasal septum is one of the most commonly encountered nasal anatomical abnormalities. Various studies showed that deviated nasal septum results in the osteo-meatal complex disease and compensatory turbinate hypertrophy. But only a few studies described the association between type and degree of angle of deviated nasal septum and measured the angle of septal deviation and explore its effect in causation of nasal symptomatology. Hence, this study was undertaken with the aim to study the relation between type and degree of septal deviation with nasal symptomatology and to measure the degree of septal deviation. This was an observational study and data collection was done from August 2017 to August 2019. A total 52 patients with symptomatic deviated nasal septum were studied. Higher septal deviation caused symptoms in 73% of cases and severe degree of angle of septal deviation caused symptoms in 63% of cases. High and severe deviated nasal are more associated with nasal symptoms. Therefore, we could derive a correlation between the cases with higher septal deviation and incidence of nasal symptoms. • Atkas D, Kalcioglu MT, Kutlu R, Ozturan O, Oncel S (2003) The relationship...

Computed tomography (CT) of the sinuses uses special x-ray equipment to evaluate the paranasal sinus cavities – hollow, air-filled spaces within the bones of the face surrounding the nasal cavity. CT scanning is painless, noninvasive and accurate. It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis. Tell your doctor if there's a possibility you are pregnant and discuss any recent illnesses, medical conditions, medications you're taking, and allergies. This exam does not commonly require contrast material; however, in some situations your doctor may request that contrast material be given. If you have a known allergy to contrast material, your doctor may prescribe medications to reduce the risk of an allergic reaction. These medications must be taken 12 hours prior to your exam. Leave jewelry at home and wear loose, comfortable clothing. You may need to change into a gown for the procedure. What is CT (Computed Tomography) of the Sinuses? Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical imaging test. Like traditional x-rays, it produces multiple images or pictures of the inside of the body. A CT scan generates images that can be reformatted in multiple planes. It can even generate three-dimensional images. Your doctor can review these images on a computer monitor, print them on film or via a 3D printer, or transfer them to a CD or DVD. CT images of intern...

• • • • • CT PNS is a CT scan of paranasal sinus cavities. CT scan is also known as Computerized tomography. It uses special x-ray equipment that provides detailed and accurate results. It is a non-invasive reliable imaging technique to detect an obstruction or inflammation in the sinus. What is paranasal sinus? The group of air-filled spaces around the nasal cavity is called paranasal sinuses. There are four pair of paranasal sinuses – • Maxillary sinuses -These are located under the eyes • Frontal sinuses – These are located above the eyes • Ethmoidal sinuses – These are located between the eyes • Sphenoidal sinuses– These are located behind the eyes Purpose of CT PNS The purpose of the CT PNS test is to detect abnormalities. Some of the common issues are: • Inflammation • Tumour • Fluid accumulation in the space • Fracture • Lining • Increase in tissue thickness • Trauma or injury Types of CT Scan PNS NCCT PNS or CT Scan PNS It is done in routine cases where simple abnormalities are to be detected. It uses low radiation and resolution. Hence it used to see even the slightest change in the vessels. CECT PNS CT PNS with contrast, though it is not common, a contrast dye is given to the patient before the CT scan. It enhances the contrast of the images. This is helpful in better diagnosis. HRCT PNS High resolution CT PNS uses high radiation and software to capture images in better resolution. Different Views in CT PNS Coronal View –Front and back part of the sinus cavity. A...
