There are four-way match of temporal, each . 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. Persistent or progressive symptoms after maximal medical therapy, in combination with CT evidence of paranasal sinus disease, should prompt referral. Likewise, the amount of radiation exposure avoided per patient was not substantial because a mean dose-length product of 338.4 mGy-cm only translates into an effective dose of 0.8 mSv.21 Although this effective dose in isolation is unlikely to cause harm to an individual, there is a constant obligation to keep medical radiation exposure as low as reasonably achievable out of concern for potentially deleterious cumulative effects.

Kennedy DW. All staff and patients are required to wear appropriate face masks and staff wear other required PPE. 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. Of the 3702 sinus CTs ordered by non-ENT providers, 167 ESS with imaging guidance (4.5%) were ultimately performed and did not require a new CT for intraoperative navigation because of the use of the universal CT protocol. Diagnostic imaging is generally used in cases of recurrent or complicated sinus disease. 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.

Introduction. NB: This article aims to frame a general concept of a CT protocol for the assessment of the paranasal sinuses. Public awareness has increased in recent years regarding the potential long-term cancer risks associated with iatrogenic radiation exposure from the rising use of CT.9 For sinus CT, radiation dose reduction strategies have included adjusting scanner parameters,1012 using bismuth eye lens shielding,13 using iterative reconstruction techniques,1416 and adopting cone-beam technology.17 However, the most-effective way to decrease the radiation dose related to sinus CT is to eliminate unnecessary examinations. 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. Usually done without contrast. Sinus computed tomography (CT) is performed for the diagnosis of paranasal sinus disease and to assess response to medical therapy. 2010; 142:55-63.
