In 2010, the two techniques were integrated such that all sinus CT began by using a single imaging protocol that was constructed and deemed mutually acceptable by neuroradiologists and sinus surgeons for both diagnostic imaging and intraoperative navigation (Fusion ENT Navigation System; Medtronic Inc, Minneapolis, MN). 149(1):17-29. Powered versus conventional endoscopic sinus surgery instruments in management of sinonasal polyposis. [9] Currently, the time from anesthesia induction until completion of registration is less than 5 minutes. 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. [Full Text]. This approach can reduce health care expenditures and patient radiation exposure. Our CT Scan tables have a weight limit of 660pounds. Chen Y-L, Liu C-M, Huang H-M.

This was an expected result because the new universal sinus CT protocol did not lower the radiation dose. Computer-augmented endoscopic sinus surgery. The mean dose-length product for the CTs was 338.4 31.9 mGy-cm (mean SD). An axial Fusion-compliant data set (standard reconstruction algorithm, 22-cm field of view, 0.625-mm slice thickness, no fiducial markers or headset required) was created and archived for all patients, regardless of whether or not ESS was planned at the time of imaging. 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. Dalgorf DM, Sacks R, Wormald PJ, Naidoo Y, Panizza B, Uren B, et al. Filter results Filter by Body Region: Start typing to search. Nauer CB, Eichenberger A, Dubach P, et al.

His ears were clear by otoscopy, and his nasal examination revealed a right-sided septal deviation. There is an exciting new development in endoscopic sinus surgery called Image Guided Surgery, a technique which allows the surgeon to correlate exactly where he or she is operating with a previously performed CT scan. Although major societies have issued and continually revise guidelines on the appropriate use of sinus CT,2,3 sinus CT utilization is unlikely to decline.4,5 Indeed, some recent studies found upfront sinus CT to be more cost effective than empiric medical therapy in the initial management of chronic rhinosinusitis.6,7 Therefore, although current usage may be partially driven by patient preference,8 sinus CTs are critical in providing cost-effective care for the patient with rhinosinusitis. 2007 Feb. 136(2):268-73. Two pulses of oral steroids produced a prolonged response that was again only temporary. 2014; 81(3-4):603-608. http://dx.doi.org/10.1016/j.wneu.2013.10.036. Multiple CTs increase cost and radiation exposure. [QxMD MEDLINE Link]. Philadelphia, PA: PMPH USA; 2001:303-316. Uncomplicated sinusitis does not require radiologic imagery.

Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2). 6 0 obj 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. Krouse JH and Christmas DA. HHS Vulnerability Disclosure, Help Up to 40 percent of asymptomatic adults have abnormalities on sinus CT scans, as do more than 80 percent of those with minor upper respiratory tract infections.14. Fourth, this approach would not be beneficial at a facility that is currently using very low radiation dose screening sinus CT for a majority of diagnostic examinations, with a higher radiation dose reserved for preoperative sinus CT. Late Wed. until 7PM Tack D, Widelec J, De Maertelaer V, et al. The objectives of this retrospective study included validating the universal sinus CT protocol, characterizing the reduction in sinus CTs that resulted, and estimating cost savings to the health care system. The time interval between sinus CT and surgery was greatest for nonotolaryngology providers (63.1 days, p < 0.01). Am J Rhinol. 2014; 81(3-4):603-608. doi.org/10.1016/j.wneu.2013.10.036. Wolcott RD, Rumbaugh KP, James G, et al. It is not a replacement for thorough anatomical training, Based on experience with both of the currently used systems, registration can be accomplished with minimal additional operating room time, Inconveniences related to the logistical setups of either system are minimal and do not affect the value of the technology, Image-guided surgery allows the surgeon to routinely perform a more complete exploration of the paranasal sinuses, particularly when it comes to smaller cells occupying the crevices of the sinus cavities, Difficult sphenoid sinus and ethmoid sinus anatomy can be approached with more surgical confidence using computer-guided dissection, Frontal sinus anatomy can be approached with greater confidence, particularly in the presence of a false lateral terminal cell. The patient was started on a four-week course of broad-spectrum antibiotics in combination with an oral steroid pulse. [QxMD MEDLINE Link]. Guilford, CT 06437, Hours: 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].

CT scans can provide much more detailed information about the anatomy and abnormalities of the paranasal sinuses than plain films. SBRT: Alternative to Surgery in Early Stage Lung Cancer? In this scenario, the potential cost savings from eliminating redundant CTs would come at the expense of increased radiation dose to a much broader group of patients. The technical storage or access that is used exclusively for statistical purposes. Some studies in image guidance have focused on real-time updates, which allow the preoperative images used for navigation to be updated throughout the surgery. [QxMD MEDLINE Link]. The patient underwent endoscopic sinus surgery with improvement of his symptoms. Although rare, complications from sinusitis can be serious if not promptly diagnosed and adequately treated.
