The electronic medical record was queried over a 4-year period to determine the number of sinus CTs performed, dose-length products, referring providers' specialties, percentage of CTs used for intraoperative navigation, and the elapsed time between CT and surgery. Sinus computed tomography (CT) is performs for the diagnosis of paranasal sinusoid disease real to assess response to medical therapy. In an attempt to decrease sinus CT utilization, we synthesized and implemented a single sinus CT protocol that was universally acceptable for diagnostic imaging and intraoperative navigation, regardless of whether ESS was anticipated at the point of order entry. A special CT scan of the sinus is done pre-operatively, and entered into the computerized system. KOLAWOLE S. OKUYEMI, M.D., M.P.H., AND TERANCE T. TSUE, M.D. Top dentist Hamidreza Nassery, DMD, has the best TMJ treatments for you. Once registered and verified, the system allows the surgeon to verify surgical position on the monitor depicting the preoperative CT scan in 3 dimensions, along with an additional frame displaying the endoscopic view of the procedure (see the image below). 2013; 270(1):149-155.

Instrumentation in endoscopic sinus surgery. OtolaryngologyHNS. NB: This article aims to frame a general concept of a CT protocol for the assessment of the paranasal sinuses. With CT scanning, numerous x-ray beams and a set of electronic x-ray detectors rotate around the patient, measuring the amount of radiation being absorbed throughout his/her body. Not only did this make it easier to reach a consensus on CT imaging protocols, but it also increased the likelihood that a patient who received a sinus CT and ultimately needed ESS would have this performed at the same institution. Persistent or progressive symptoms after maximal medical therapy, in combination with CT evidence of paranasal sinus disease, should prompt referral. [2, 3, 4]. Bethesda, MD 20894, Web Policies Although worth acknowledging, these limitations did not significantly hamper the results. Multiple CTs increase cost and radiation exposure. 2005 Jun. As for the specific of mAs, kVp and dose reduction on your scanner please get this information from your scanner provider. 2002 Jul-Aug. 16(4):193-7. Although the answer to this question may differ from one platform to the next, two studies assessed the impact of radiation dose reduction for ESS on the BrainLAB system (Feldkirchen, Germany) with phantom and cadaver testing.25,27 They found that the technical accuracy of surface registration was not dose dependent, and surgical landmarks could also be identified even at very low radiation doses. We will keep you up to date on these new developments as we expand this section. PDF American Journal of Neuroradiology This technology enables the surgeon to follow the anatomic dissection of the sinuses on a computer monitor in the operating room in real time. Our Advanced Sequences and Protocols for conditions like chronic sinusitis, hearing loss, ear infections, dysphagia, sleep apnea, tonsils and adenoid problems, vertigo, allergies, and head and neck cancer. As such, all patients referred for sinus CT regardless of clinical indication were imaged under this universal protocol by using a 64-detector CT scanner (Lightspeed VCT or Discovery CT750HD; General Electric, Waukesha, WI), with the following imaging parameters: 120 kV, 180 mA, 0.5-second rotation time, 0.531 pitch, and .625-mm section Current electromagnetic image-guided surgery (IGS) system (InstaTrak 3500 Plus, GE Medical Systems, formerly Visualization Technologies, Inc.). This is especially helpful in cases of revision surgery, unusual anatomic structures or nasal polyps, all of which can make visualization of the normal sinonasal structures more difficult. 3(3):236-41.

I'm not a radiologist but I believe it has to do with overlaying the images in a particular manner and the use of specialized software. Using specialized equipment and expertise to create and interpret CT scans of the body, radiologists can more easily diagnose problems such as cancers, cardiovascular disease, infectious disease, appendicitis, trauma and musculoskeletal disorders. However, given that there is significant variability in payer mix across practices, the use of Medicare rates allowed for a more generalizable result. Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you. Referral will occasionally be needed in unusual or complicated cases. Today with numerous CT scan manufacturers around the world and with numerous makes and models of scanners constantly changing it is essentially impossible to provide a set of protocols for what would likely be 100 different scanners.

The CT scan acquisition protocol used for the authors' needs consists of a helical, 2-mmthickness axial CT scan with the use of a specially designed headset incorporating built-in metallic fiducial land marking. Disadvantages of MRI include high false-positive findings, poor bony imaging, and higher cost. Acute cerebral venous sinus thrombosis (VST) is a rare form of stroke, and establishing a correct diagnosis can be challenging due to its diverse and typically delayed clinical presentation [1,2].VST is most common in young women and is associated with pregnancy/puerperium, use of hormonal contraceptives, hypercoagulable states, and malignancy [3,4]. As such, their conclusion was that the primary limiting factor for radiation dose reduction is the surgeon's willingness to accept impaired image quality. HKMJ. "What will a CT scan of my sinuses reveal?" - Zocdoc Laryngoscope. I noticed on my appointment for Monday that I am having a CT with fusion protocol done on my sinuses. It does not imply the use of a contrast agent. Powered versus conventional endoscopic sinus surgery instruments in management of sinonasal polyposis.

These localization maneuvers should be performed with diagnostic instruments, not surgical instruments. Allergy Asthma Rep. 2007; 7(3):216-220. Although mucosal thickening is seen in more than 90 percent of sinusitis cases, it is very nonspecific.68 Air-fluid levels and complete opacification are more specific for sinusitis but are seen in only 60 percent of sinusitis cases.6 Interpretation of plain radiographs can vary widely among different observers, and there is a high rate of false-negative results.2,9, Radiographs of the sinuses in infants aged three years or younger are not useful because of false opacification from undeveloped sinuses.10 Other important limitations of plain radiographs include poor visualization of ethmoid air spaces and difficulty differentiating between infection, tumor, and polyp in an opacified sinus.2, Because clinical judgment is sufficient to diagnose sinusitis in a majority of cases, and empiric treatments are inexpensive and safe, only a small percentage of patients who develop recurrent or complicated sinusitis are candidates for imaging studies. sharing sensitive information, make sure youre on a federal Clearing the operative field of blood and debris and then using either a tracking pointer or a tracking curved suction to elucidate anatomicquestions is most prudent for the surgeon, who may then proceed safely with the next step of surgery. There are several manufacturers now including InstaTrak by GE,, BrainLAB, Medtronic (LandmarX) Fusion, and Stryker iNtellect ENT . [10], The relevant anatomy is that of the paranasal sinuses, orbits, and cranial base and is comprehensively treated in many textbooks such as Stammberger'sFunctional Endoscopic Sinus Surgery(1991). <> 38(3):505-13, vii. . We will try to make this a problem based approach (e.g. Old image-guided surgery (IGS) systems used an articulated arm (shown) and required the patient's head to be taped to the operating room bed.
