Smith TL, Litvack JR, Hwang PH, et al. [QxMD MEDLINE Link]. 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. Historically, sinus CT at our institution (a multispecialty academic medical center) was performed in the radiology department by using one of two imaging protocols, based on whether the CT was intended for diagnostic purposes or intraoperative navigation, neither of which would be considered a low-radiation dose screening sinus CT. We have staggered patient exam times to avoid congestion and reduce any unnecessary potential exposure. Anand VK. With the newer systems (see the second image below), the headset moves along with the head, so registration is maintained throughout the procedure, although frameless registration can also be performed. Nasal endoscopy revealed bilateral profuse mucus that required suctioning. A noncontrast CT scan is usually sufficient, except for complicated acute sinusitis (e.g., periorbital cellulitis or abscess). These localization maneuvers should be performed with diagnostic instruments, not surgical instruments. Although the senior author has experimented with magnetic resonance for this purpose, this imaging modality was deemed inadequate for routine use because of extremely high costs and implementation constraints. The paranasal sinuses are hollow, air-filled places located within the remains von the face and environs of nose cavity, a system of air tv connecting the nasal with an support of the jaw. Exam rooms and equipment are thoroughly disinfected after each patient, from mammography paddles to the CT & MRI bores, to the exam tables, counters, and areas of patient contact. Dalgorf DM, Sacks R, Wormald PJ, Naidoo Y, Panizza B, Uren B, et al. However, successful implementation must take into account multiple practice-based considerations. DOC IGS_Medtronic_Stryker sinus v1.0 - ARA Diagnostic Imaging Old image-guided surgery (IGS) systems used an articulated arm (shown) and required the patient's head to be taped to the operating room bed. Specifically, does a noisier image impair surface registration and thereby decrease navigation accuracy? Additionally, the navigation system confirms the positions of the surgeons instruments by superimposing them on the CT scan images. 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. Leong JL, Batra PS, Citardi MJ. Commonly this is used evaluating the spine after surgery with fusion hardware in place. [10], The relevant anatomy is that of the paranasal sinuses, orbits, and cranial base and is comprehensively treated in many textbooks such as Stammberger'sFunctional Endoscopic Sinus Surgery(1991). An official website of the United States government. 1, 23.9% of patients (278/1162) referred for sinus CT by sinus surgeons underwent ESS with imaging guidance, whereas this percentage was 11.4% (151/1323) for the remainder of the ENT department.

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. 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). I would call and ask her tomorrow, but the office is closed on Friday. Am J Rhin. /Contents 6 0 R>> Depending on the severity of disease and whether significant fluctuation is anticipated based on treatment (or lack thereof), it may still be necessary to repeat a preoperative CT for updated planning purposes. Once registered and verified, the system allows the surgeon to verify surgical position on the monitor depicting the preoperative CT scan in 3 dimensions, along with an additional frame displaying the endoscopic view of the procedure (see the image below).

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. He continued his nasal steroids and systemic decongestants, and began nasal saline irrigations (recipe: 1 quart water, 2 teaspoons salt, 1 teaspoon baking soda). However, the images produced by this modality remain inadequate for nearreal-time navigation. Please do not bring anyone with you to your exam as we are trying to reduce traffic in our office, special accommodations can be made as needed. [QxMD MEDLINE Link]. A special CT scan of the sinus is done pre-operatively, and entered into the computerized system. Possible findings in acute sinusitis include mucosal thickening, air-fluid levels, and complete opacification of the involved sinus. The original goal of www.ctisus.com was to provide a source for CT scan protocols nearly 25 years ago. NB: This article aims to frame a general concept of a CT protocol for the assessment of the paranasal sinuses. This approach can reduce health care expenditures and patient radiation exposure. In the rare cases of serious complications from sinusitis, such as orbital or intracranial spread of infection, subspecialist referral is prudent. Image-guided endoscopic sinus surgery is also reaching increasing acceptance in pediatric otolaryngology, although fewer reports have been published compared with the adult literature. If an initial diagnostic CT was not performed with the appropriate parameters, then an additional CT would be necessary for intraoperative imaging guidance, which thereby leads to added expense and radiation exposure. Third, the time that elapses between the sinus CT and ESS must be taken into account. These advances, as well as the decreasing cost of the technology, have allowed IGS to be available to a sizable number of otolaryngologists. 3-D reconstructions are done as needed. many centers still have a specific 3D navigation protocol and a specific standard CT protocol for sinus CT scans [17].
