Patients with an age <18 years were specifically excluded. The imaging data set is transferred via optical disk, CD-ROM, or computer network to the operating room, where it is loaded into the workstation. The enhanced vision is especially useful in revision cases & extensive sinus diseases which have poor anatomical landmarksl. Adopting a single universal sinus CT protocol for diagnostic imaging and intraoperative navigation can be an effective means of decreasing cost and radiation exposure. [5]. CT scans can provide much more detailed information about the anatomy and abnormalities of the paranasal sinuses than plain films. Although first developed for neurosurgery, endoscopic sinus surgery (ESS) rapidly became one of the leading indications for this technology. Copyright 2002 by the American Academy of Family Physicians. Ear, Nose & Throat In chronological order, Medicare prices for the combined technical and professional fees for sinus CT from 2010 to 2014 were $247.48, $259.36, $246.27, $227.20, and $206.91. 3 Transform your office by: Bringing OR technology to your office procedure rooms Providing additional navigated treatment options DISCUSSION The use of a universal sinus CT protocol for both intraoperative navigation and routine diagnostic imag-ing represents an easily overlooked opportunity for eliminating redundant imaging. 38(3):505-13, vii. The time interval between sinus CT and surgery was greatest for nonotolaryngology providers (63.1 days, p < 0.01). Second, the CT scanner(s) used must be able to meet the technical requirements set forth by the imaging guidance system, such as the minimum field of view and slice thickness. and transmitted securely.
