The olfactory pathway is composed of peripheral sinonasal and central sensorineural components. RadiologyInfo.org is not a medical facility. He subsequently underwent a successful frontal sinus obliteration to prevent future episodes of frontal sinusitis. Keep in mind that the images provided are based on the anatomy at the time of CT scan and the surgical anatomy may have changed prior to the start of the procedure (resolution/progression of infection, change in size of masses, etc). If the exam uses iodinated contrast material, your doctor will screen you for chronic or acute kidney disease. Our CT scanner uses cone beam technology to focus just on the sinuses. Some CT exams use a contrast material to enhance visibility in the body area under examination. 2006 Apr;116(4):564-72. Wear comfortable, loose-fitting clothing to your exam. The CT images and direct views from the endoscope are visualized throughout the procedure. Image-guided surgery (IGS) is the use of a real-time correlation of the operative field to a preoperative imaging data set that reflects the precise location of a selected surgical instrument to the surrounding anatomic structures. To the left of the picture are inputs for the EGM cords (shown in figure 4). Sometimes, the exam table will move during the scan. The paranasal sinuses are hollow, air-filled spaces located within the bones of the face and surrounding the nasal cavity, a system of air channels connecting the nose with the back of the throat. The patient is a 37-year-old man who smokes. The actual CT scan takes less than a minute and the entire process is usually completed within 10 minutes. Noncontrast coronal computed tomographic (CT) images can define the nasal anatomy much more precisely. Then, the table will move slowly through the machine for the actual CT scan. ENT Navigation Solutions You will be asked to lie on a narrow table that slides into the center of the CT scanner. These lines help ensure that you are in the correct position on the exam table. The optical capability refers to the infrared light based camera that monitors reflections from the spheres placed on the surgical instrumentation.

Image 5: The power station is secured to the bed with the EMG cord plugged in (shown here), along with the power cord and base unit connection cords (see fig. CT imaging allows providers to have a more in-depth look at your sinuses to determine the cause of blockages. They will cover the tiny hole made by the needle with a small dressing. /G3 gs Different body parts absorb x-rays in different amounts. The CT paranasal sinus protocol serves as an examination for the assessment of the study of the mucosa and bone system of the sinonasal cavities. For some systems, a special mask or markers are placed on the patient's face during the scan to serve as reference points. CT exams are generally painless, fast, and easy. endstream See permissionsforcopyrightquestions and/or permission requests. Immunocompromised persons and smokers are at increased risk for serious sinusitis complications. This is accomplished through: Benefits of image-guided navigated surgery include improvements in visualization, enabling surgeons to work within complex sinus anatomy and optimize surgical strategies for their patients.5-9. A special CT scan of the sinus is done pre-operatively, and entered into the computerized system.
