Mucosal thickening, polyps, and other sinus abnormalities can be seen in 40 percent of symptomatic adults; however, clinical correlation is needed to avoid overdiagnosis of sinusitis because of nonspecific CT findings. 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). However, when electromagnetic systems are used, a thick foam mattress is needed to keep the patient off of the metal table in order to prevent interference. Disadvantages of MRI include high false-positive findings, poor bony imaging, and higher cost. The system is then used during the surgery to confirm the position of the surgeons instruments at all times. Laryngoscope. To provide an estimate of costs, the combined technical and professional fees for sinus CT (CT maxillofacial without dye; Level I Health Care Common Procedural Coding SystemCurrent Procedural Terminology Code 70486) was obtained for 20102014 by using the Physician Fee Schedule search tool from the Centers for Medicare & Medicaid Services Web site (carrier locality, 310200).19 The total cost was adjusted for inflation by using Consumer Price Index data to determine the present value for June 2015.20. Navigation System; Medtronic Inc, Minneapolis, MN). At the same time, the examination table is moving through the scanner, so that the x-ray beam follows a spiral path. Lusk R.

Surgeon's view of the computer monitor showing the sagittal, axial, and coronal depictions in real time of the surgery progress. IGS should not be considered as a way to palliate lack of experience or understanding of sinonasal surgical anatomy but rather as an adjunctive tool designed for otolaryngologists properly trained in ESS. Dalgorf DM, Sacks R, Wormald PJ, Naidoo Y, Panizza B, Uren B, et al. 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. 2001; 7(2):189-192. 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. The application of a free nasal floor mucoperiosteal graft in endoscopic sinus surgery. An official website of the United States government. Use of CT is typically reserved for difficult cases or to define anatomy prior to sinus surgery. They also can be printed or transferred to a CD. This was an expected result because the new universal sinus CT protocol did not lower the radiation dose. [17]. If you choose to check-in in our lobby, comie in and stop at the front desk, please arrive at your requested time andenter our comfortable clean reception area with your ID, insurance card and order (if applicable) in hand. Both systems are widely accepted and provide excellent anatomic information. [13]. 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. Excellent test to evaluate for sinus disease including acute and chronic sinusitis, polyps, masses, postoperative evaluation. CT Navigation Setup for Image Guided Surgery-Sinus and Skull Base Not consenting or withdrawing consent, may adversely affect certain features and functions. Computer-augmented endoscopic sinus surgery. Philadelphia: BC Decker; 1991. 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. In our study, 24% (4/17) of pediatric patients and 41% (21/51) of adult patients undergoing 3D navigation sinus CT had already had a sinus CT for the same episode of care. [6] As experience has been gained, image guidance has become an integral part of surgery for many otolaryngologists performing endoscopic sinus surgery, particularly in the following situations: Sinus surgery in the absence of normal landmarks, Disease that abuts the skull base The authors have no conflicts of interest to declare pertaining to this article, Presented in preliminary form as an oral abstract at the American Society of Neuroradiology Meeting, May 22, 2014, Montreal, Quebec, Canada, National Library of Medicine Krouse JH and Christmas DA. Otolaryngol Head Neck Surg. Condoms are the most effective way to prevent HIV and STDs. There has been considerable work done recently on radiation dose from CT scans. 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. 6 0 obj Anand VK. Although first developed for neurosurgery, endoscopic sinus surgery (ESS) rapidly became one of the leading indications for this technology. 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. Immunocompromised persons and smokers are at increased risk for serious sinusitis complications. Our Advanced Sequences and Protocols for conditions like chronic sinusitis, hearing loss, ear infections, dysphagia, sleep apnea, tonsils and adenoid problems, vertigo, allergies, and head and neck cancer.

The effect of decreasing mAs on image quality and patient dose in sinus CT, Multidetector CT of the paranasal sinus: Potential for radiation dose reduction. Am J Rhinol. An image depicting image-guided surgery is shown below. He appeared healthy on examination and had hyponasal speech. what's the protocol for an incidental adrenal lesion) and help you optimize your protocols on a daily basis. 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. Tell your doctor if there's a possibility you are pregnant and discuss any recent illnesses, medical conditions, medications you're taking, and allergies. CT-MR image fusion for the management of skull base lesions. However, the images produced by this modality remain inadequate for nearreal-time navigation. 5 0 obj It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis. zhMPLOsFpa;i~ Accuracy is verified by testing various known landmarks on the patient's face and intranasally to the images on the computer monitor (see the image below).

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. 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. If you log out, you will be required to enter your username and password the next time you visit. MRI allows better differentiation of soft tissue structures within the sinuses. 2008; 118: 1270-1274.

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). [QxMD MEDLINE Link]. Leong JL, Batra PS, Citardi MJ. Comparison of microdebrider-assisted inferior turbinoplasty and submucosal resection for children with hypertrophic inferior turbinates. PDF Imaging Protocols c 800.595.9709 or (+1) 720.890 - Chattanooga Imaging Sinonasal cancers are quite uncommon, with an annual incidence of less than 1:100,000 in the United States. [16] The image-guidance system can create a hybrid image that has both excellent soft tissue and bony detail. Advances in diagnostic imaging techniques (e.g., computed tomographic [CT] scan and magnetic resonance imaging [MRI]) have enhanced the understanding and management of sinusitis. 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 addition, sinus CT is used for intraoperative imaging guidance. 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. (All locations). However, when symptoms are recurrent or refractory despite adequate treatment, further diagnostic evaluations may be indicated. 2010; 142:55-63. Int Forum Allergy Rhinol. If a Stealth protocol CT impossible be gained, a normal sinus CT can be uses but can not provide the same level of accuracy. In all the cases used for intraoperative navigation, the sinus surgeons deemed the sinus CTs acquired with the universal protocol to be technically adequate. Based on Medicare reimbursement, the total estimated saving was $147,628. Cranial DRF: Skull-mounted patient tracking for EM surgical navigation, Setty P, Volkov AA, D'Andrea KP, Pieper DR.

Gross CW, Becker DG. 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. 1998 Aug. 108(8 Pt 1):1164-70. Am J Rhinol Allergy. In this image, the surgeon is attempting to localize the right sphenoid sinus during image-guided surgery. 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 CT images and direct views from the endoscope are visualized throughout the procedure. <> Multiple CTs increase cost and radiation exposure. Imaging Protocols. 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. 2014; 10(260). Epidemiology and economic impact of rhinosinusitis. [QxMD MEDLINE Link]. Evaluation of a new and simple classification for endoscopic sinus surgery. Physicians must be aware that the technique is an adjunct to surgery and does not replace surgical skills and knowledge. PDF Equipment Lease Financing - Commercial Capital Company, LLC The following observations of IGS have been consistent since the earliest cases in the authors' institution: Image-guided surgery assists the experienced surgeon in delineating ambiguous or distorted landmarks. The cross-hairs are clearly located on the right sphenoid sinus. The location is materialized by a set of cross hairs on the screen that moves through the CT image data in concordance with the movement of the pointer. Stewart AE, Stalp JT, Futerman C, Vaughan WC. endobj Fried MP, Moharir VM, Shin J, et al. Biofilm maturity studies indicate sharp debridement opens a time-dependent therapeutic window. 3-D reconstructions are done as needed. CT scan of the paranasal sinuses with Stealth protocol should be ordered prior to the patients surgery date. MEDICAL PROFESSIONAL Michael H Kirsch, DDS CT with fusion is a radiological technique used to enhance the images. A higher percentage of CT referrals from sinus surgeons (23.9%) and other otolaryngology providers (11.4%) was used for imaging guidance (p < 0.0001). Intl J Ped Otorhinolaryn.
