Lui WM, Leung GKK, Hui Y, Lee KK, Fan YW. zhMPLOsFpa;i~ These advances, as well as the decreasing cost of the technology, have allowed IGS to be available to a sizable number of otolaryngologists. The electronic medical records for all outpatients undergoing sinus CT between October 1, 2010, and September 30, 2014, were queried. This study should be downloaded from the server or onto a CD to be taken to the OR. 2009; 266(6):839-45. 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. Magnetic resonance imaging (MRI) cannot define bony anatomy as well as CT. MRI is only used to differentiate soft-tissue structures, such as in cases of suspected fungal infection or neoplasm. The .gov means its official. During the study period, 876 ESS cases were performed, and 596 used imaging guidance (68.0%). His nasal symptoms improved after he started taking decongestants and antibiotics, but a persistent headache prompted a visit back to his family physician. May 2004; 113(5):3-5. Rhinology. In: Kennedy DW, Bolger WE, Zinreich SJ, eds.

With CT scanning, numerous x-ray beams and a set of electronic x-ray detectors rotate around the patient, measuring the amount of radiation being absorbed throughout his/her body. 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. Medtronic's innovative products and integrated technologies can help you address the unique challenges of transnasal skull base surgery. [5]. The use of a microdebrider with tracking is of exceptional benefit while removing nasal and sinus polyp disease.

Therapies & Procedures The Fusion Navigation System allows the surgeon to perform image-guided endoscopic sinus surgery. This technology is beneficial in cases that involve both otolaryngologists and neurosurgeons, as one image-guidance system can be used for navigation. Diseases of the Sinuses: Diagnosis and Management. PATIENT FORMS In all the cases used for intraoperative navigation, the sinus surgeons deemed the sinus CTs acquired with the universal protocol to be technically adequate. Powered sinus surgery with a microdebrider has several benefits compared to surgery with manual instruments alone: Hands-on training at the Dr. Glen Nelson Education and Training Center. 2017 Oct 1. 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. CT images are indeed able to better delineate the bony anatomy of sinonasal cavities for the nasal approach performed by the otolaryngologist, whereas the neurosurgeon will require the assistance of MRI guidance with enhanced intracranial soft tissue definition to pursue the combined procedure. Accessibility This has enormous implications for surgeons who prefer local or intravenous sedation. In this difficult and highly vascular area, maximum visualization and access are key. 2002; 5(4):218-225.

Of all the patients who had a sinus CT, the proportion that ultimately underwent ESS with imaging guidance differed based on the specialty of the referring provider (p < 0.0001). Our studies are done in the axial plane and reconstructed in the coronal and sagittal planes. Arlen D Meyers, MD, MBA Professor of Otolaryngology, Dentistry, and Engineering, University of Colorado School of Medicine 2014; 81(3-4):603-608. http://dx.doi.org/10.1016/j.wneu.2013.10.036. Although worth acknowledging, these limitations did not significantly hamper the results. Because reimbursement records were not available to determine exact amounts billed and collected for each CT, Medicare rates were applied. Both systems are widely accepted and provide excellent anatomic information. 12 A CT scan provides greater definition of the sinuses and is . He also had a large air cell (i.e., con-cha bullosa) within the left middle turbinate, which likely contributed to obstruction of ostia draining adjacent sinuses (Figure 1, part B). Not only did this make it easier to reach a consensus on CT imaging protocols, but it also increased the likelihood that a patient who received a sinus CT and ultimately needed ESS would have this performed at the same institution. CT Sinus Cat Scan Quick Reference Guide for Physicians - Guilford Radiology CT Head, Face, Sinus, Temporal - Chattanooga Imaging Image-guided surgery influences perioperative morbidity from endoscopic sinus surgery: a systematic review and meta-analysis.
