Share cases and questions with Physicians on Medscape consult. We offer routine ENT MRI and CT sequences and protocols with and without contrast. 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. However, successful implementation must take into account multiple practice-based considerations. Comparison of endoscopic sinus surgery with and without image guidance. The original goal of www.ctisus.com was to provide a source for CT scan protocols nearly 25 years ago. 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). The original goal of www.ctisus.com nearly 25 years ago was to provide a source for CT scan protocols.

Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2). 2008; 118: 1270-1274. 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. [QxMD MEDLINE Link]. Two pulses of oral steroids produced a prolonged response that was again only temporary. ct of sinuses with fusion - Oral and Maxillofacial Surgery - MedHelp The surgeon should ensure the desired patient, date of study, and anatomical location are obtained. 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. 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. The instruments are registered to show their position with respect to the orthogonal CT images of the patient. 3 Transform your office by: Bringing OR technology to your office procedure rooms Providing additional navigated treatment options Philadelphia: BC Decker; 1991. The images are brought up on the IGS system prior to the procedure and checked for image quality and accuracy. Referral will occasionally be needed in unusual or complicated cases. Answer A CT sinus scan is not an unreasonable option, particularly if you have a history of sinus disease, or if you have sinus congestion/infection currently. ENT Imaging Capabilities. During the study period, 876 ESS cases were performed, and 596 used imaging guidance (68.0%). Newer methods are available for automated registration; for instance, small cranial pin transmitters designed to replace the more bulky headsets currently in use may have exceptional benefit in open skull base or orbital cases. Although the initial expense is substantial, these procedures have minimal per-case costs. Bones appear white on the xray; soft tissue shows up in shades of gray and air appears black. May 2004; 113(5):3-5. The Fusion Navigation System allows the surgeon to perform image-guided endoscopic sinus surgery.
