Dadgostar A, Okpaleke C, Al-Asousi F, Javer A. Initially, because of the cumbersome nature of the systems, increased operating time, and expertise required of operating room personnel, image-guided surgery was selected only by tertiary referral centers for revision or unusual sinus cases in which the anatomy was expected to be distorted. 2006 May. 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. 110(6):972-6. Patients can choose to checkin in our waiting room or wait in their car. This has enormous implications for surgeons who prefer local or intravenous sedation. endobj Clin Otolaryngol. In a conventional x-ray exam, a small burst of radiation is aimed at and passes through the body, recording an image on photographic film or a special image recording plate.

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. This technique is called helical or spiral CT. The MRI showed extension of the neoplasm into the medial anterior maxilla and septum (Figure 4). CT scanning combines special x-ray equipment with sophisticated computers to produce multiple images of the inside of the body. Haruna S, Otori N, Moriyama H, Kamio M. Endoscopic transnasal transethmosphenoidal approach for pituitary tumors: assessment of technique and postoperative findings of nasal and paranasal cavities. Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2). The mean time interval between sinus CT and ESS was longer (p < 0.01) for non-ENT (63.1 58.3 days [SD]) compared with sinus surgeons (42.5 50.9 days [SD]) or the remaining ENT providers (45.1 51.2 days [SD]). 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). Krouse JH and Christmas DA. Immuno-compromised patients are at increased risk for complicated bacterial or fungal infections. 6 0 obj Physicians must be aware that the technique is an adjunct to surgery and does not replace surgical skills and knowledge.

First of all, if a navigation system requires a stereotactic headset or fiducial markers to be worn during the CT acquisition, then it would not be cost effective to follow this procedure for a majority of CTs that will never be used for navigation. These advances, as well as the decreasing cost of the technology, have allowed IGS to be available to a sizable number of otolaryngologists. )a8QBJo,k'rY)Z4Z0u>p^B D;v)$g9SO#`L v6f&a^nw\4 Even though some centers use a unique acquisition protocol, many centers still have a specific 3D navigation protocol and a specific standard CT protocol for sinus CT scans .

FOIA MEDTRONIC SEAFARING, FUSION. 1591 Boston Post Road, Suite 106 Nauer CB, Eichenberger A, Dubach P, et al. A total of 6187 sinus CTs were performed by using a 64-detector scanner during the study period (2759 women and 3428 men; 53.6 16.7 years [mean SD]), and 596 endoscopic sinus surgery cases used imaging guidance, for which all the CTs were deemed technically adequate. The American Academy of OtolaryngologyHead and Neck Surgery recognizes the important role of computer-aided endoscopic sinus surgery (ESS) in delineating cases with complex anatomy.18 One nuance in using surgical navigation systems is that they have specific technical requirements for CT to permit accurate image coregistration as well as to satisfactorily delineate bony anatomy. The fourth window can be either the real time video or a computer 3-dimensional rendition of the surgical field. .

Statistical analysis was performed by using JMP 10.0.0 (SAS Institute Inc, Cary, NC). In many ways CT scanning works very much like other x-ray examinations. These localization maneuvers should be performed with diagnostic instruments, not surgical instruments. Imaging Protocols. Home Diagnostic imaging is generally used in cases of recurrent or complicated sinus disease. J Wound Care. This was an expected result because the new universal sinus CT protocol did not lower the radiation dose. Consequently, the subset of patients that ultimately needed ESS would not require repetitive imaging. 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. Differences in the mean time between sinus CT and ESS among the three groups were assessed by using one-way analysis of variance with the Dunn Multiple Comparison Test. CT Navigation Setup for Image Guided Surgery-Sinus and Skull Base Gross CW, Becker DG. This technology enables the surgeon to follow the anatomic dissection of the sinuses on a computer monitor in the operating room in real time.
