Am J Rhin. xE0EwhD7c@5#B7X Smith TL, Litvack JR, Hwang PH, et al. Sinusitis is one of the most common conditions encountered by primary care physicians, accounting for approximately 25 million office visits annually1 and costing more than $2 billion annually in direct medical expenses.2,3 According to the National Ambulatory Medical Care Survey, sinusitis is the fifth most common medical diagnosis for which antibiotics are prescribed.4,5. A single Waters' view (occipitomental) appears to provide as much information as the standard four-view series.11, CT scans can provide much more detailed information about the anatomy and abnormalities of the paranasal sinuses than plain films.12 A CT scan provides greater definition of the sinuses and is more sensitive than plain radiography for detecting sinus pathology, especially within the sphenoid and ethmoid sinuses.6,13 CT scan findings can also be quite nonspecific, however, and should not be used routinely in the diagnosis of acute sinusitis.6,14 The primary role of CT scans is to aid in the diagnosis and management of recurrent and chronic sinusitis, or to define the anatomy of the sinuses prior to surgery.2 In many institutions, a limited CT scan costs about the same as a full radiographic series but provides more useful information.2,15,16, A coronal CT image is the preferred initial procedure. The presented data were derived from an integrated multispecialty academic practice. 1996; 7(3):236-241. A CT scan of the surface produces images that also show an patient's paranasal sinus cavities. At the same time, the examination table is moving through the scanner, so that the x-ray beam follows a spiral path. Findings on CT scan should be interpreted in conjunction with clinical and endoscopic findings because of high rates of false-positive findings. As such, their conclusion was that the primary limiting factor for radiation dose reduction is the surgeon's willingness to accept impaired image quality. If you suffer from frequent headaches, jaw clicking and popping ear pain, you may have TMJ. His symptoms failed to improve after a prolonged antibiotic and decongestant course. He subsequently underwent a successful frontal sinus obliteration to prevent future episodes of frontal sinusitis. Functional endoscopic sinus surgery: concepts, surgical indications, and instrumentation. Two pulses of oral steroids produced a prolonged response that was again only temporary. His ears were clear by otoscopy, and his nasal examination revealed a right-sided septal deviation. Haruna S, Otori N, Moriyama H, Kamio M.

The fourth window can be either the real time video or a computer 3-dimensional rendition of the surgical field. The paranasal sinuses are hollow, air-filled places located within the remains von the face and environs of nose cavity, a system of air tv connecting the nasal with an support of the jaw. Any practice that considers the use of a universal sinus CT protocol would have to take this lag into account based on local referral patterns and wait times. Sinusitis is one of the most common diseases treated by primary care physicians. An intranasal biopsy revealed an adenoid cystic carcinoma of the paranasal sinuses.

In instances in which a patient had multiple sinus CTs, the date of the most recent CT before surgery was used. A total of 6187 sinus CTs performed during the study period met inclusion criteria and had a mean dose-length product of 338.4 31.9 mGy-cm (mean SD). All rights reserved. Am J Rhinol.

Certain logistical considerations may make it impractical to use a common protocol for diagnostic sinus CT and imaging-guided ESS. Destination on medtronic protocol cpt cysts or nursing females have not medical images are happy to compare the property of bone or an ent. The current study had multiple limitations. Accessibility Historically, sinus CT at our institution (a multispecialty academic medical center) was performed in the radiology department by using one of two imaging protocols, based on whether the CT was intended for diagnostic purposes or intraoperative navigation, neither of which would be considered a low-radiation dose screening sinus CT. Persistent or progressive symptoms after maximal medical therapy, in combination with CT evidence of paranasal sinus disease, should prompt referral. 110(6):972-6. Three aspects of direct coronal imaging of the paranasal sinuses were investigated: (1) preparation of the patient prior to the examination; (2) technical factors of the CT study, including positioning of the patient, optimal coronal angle, slice thickness, and CT exposure factors; and (3) data display.

Image-Guided Surgery: Practice Essentials, Indications and - Medscape The use of a universal sinus CT protocol for both intraoperative navigation and routine diagnostic imaging represents an easily overlooked opportunity for eliminating redundant imaging. Fried MP, Kleefield J, Gopal H, et al. 2009;119:414-418. Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2). 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. This was an expected result because the new universal sinus CT protocol did not lower the radiation dose. CT sinus fusion protocol, axial view. Midline septal mass and notable Metson RB, Cosenza MJ, Cunningham MJ, et al. zhMPLOsFpa;i~ To determine potential cost savings and radiation dose reduction that result from the use of a single universal sinus CT protocol for diagnostic imaging and intraoperative navigation. 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 0.625-mm section collimation.
