His nasal symptoms improved after he started taking decongestants and antibiotics, but a persistent headache prompted a visit back to his family physician. This is very useful following patients with dementia, seizures, and neurodegenerative diseases. The time interval between sinus CT and surgery was greatest for nonotolaryngology providers (63.1 days, p < 0.01). 2005 Jun. Image-guided endoscopic sinus surgery is also reaching increasing acceptance in pediatric otolaryngology, although fewer reports have been published compared with the adult literature. A noncontrast CT scan is usually sufficient, except for complicated acute sinusitis (e.g., periorbital cellulitis or abscess). However, successful implementation must take multiple considerations into account, including radiologist and surgeon preferences for image quality, technical requirements for imaging guidance systems, and other local practice differences. Karen H Calhoun, MD, FACS, FAAOA Professor, Department of Otolaryngology-Head and Neck Surgery, Ohio State University College of Medicine Referral will occasionally be needed in unusual or complicated cases.

Radiologic Imaging in the Management of Sinusitis | AAFP Adopting a single universal sinus CT protocol for diagnostic imaging and intraoperative navigation can be an effective means of decreasing cost and radiation exposure. As such, all patients referred for sinus CT regardless of clinical indication were imaged under this universal protocol by using a 64-detector CT scanner (Lightspeed VCT or Discovery CT750HD; General Electric, Waukesha, WI), with the following imaging parameters: 120 kV, 180 mA, 0.5-second rotation time, 0.531 pitch, and 0.625-mm section collimation. These localization maneuvers should be performed with diagnostic instruments, not surgical instruments. We have staggered patient exam times to avoid congestion and reduce any unnecessary potential exposure. Jennifer Bock Hughes, M.D. They arise primarily in the setting of cystic degeneration of the sinus mucosa or. Specifically, does a noisier image impair surface registration and thereby decrease navigation accuracy? Sinusitis is one of the most common diseases treated by primary care physicians. Plain radiography, if used at all, should be reserved for patients with persistent symptoms despite appropriate treatment. American Academy of Otolaryngology-Head and Neck Surgery, American Bronchoesophagological Association, American Society for Laser Medicine and Surgery, Society of University Otolaryngologists-Head and Neck Surgeons, American Academy of Facial Plastic and Reconstructive Surgery, Association for Research in Otolaryngology, American Society of Pediatric Otolaryngology, Canadian Society of Otolaryngology-Head & Neck Surgery. 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]. Late Wed. until 7PM Fried MP, Morrison PR. <> Plain radiography has a limited role in the management of sinusitis. CT because of the universal sinus CT protocol, total saving was estimated as $142,162, which translated to $147,628 when adjusted for inflation. 2008; 118: 1270-1274. These annotations will then be available in real-time on the IGS system during surgery. Second, the CT scanner(s) used must be able to meet the technical requirements set forth by the imaging guidance system, such as the minimum field of view and slice thickness. At our tertiary care multispecialty institution, >500 health care providers have access to ordering sinus CTs. 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. Transnasal skull base surgery typically involves both a neurosurgeon and an ENT surgeon. The system is then used during the surgery to confirm the position of the surgeon's instruments at all times. Commonly this is used evaluating the spine after surgery with fusion hardware in place. Creates 3-D imaging models for surgical procedures. Such speed is beneficial for all patients but especially children, the elderly and critically ill. For children, the CT scanner technique will be adjusted to reduce the radiation dose.

The quality of the CT or CBCT scan is the most important aspect of creating Furthermore, no significant difference was noted in other parameters (eg, blood loss, complications). The American Academy of OtolaryngologyHead and Neck Surgery recognizes the important role of computer-aided endoscopic sinus surgery (ESS) in delineating cases with complex anatomy.18 One nuance in using surgical navigation systems is that they have specific technical requirements for CT to permit accurate image coregistration as well as to satisfactorily delineate bony anatomy. Immuno-compromised patients are at increased risk for complicated bacterial or fungal infections. DISCUSSION The use of a universal sinus CT protocol for both intraoperative navigation and routine diagnostic imag-ing represents an easily overlooked opportunity for eliminating redundant imaging. Now more than ever, the safety of our patients, community and staff is our top priority. Of the 3702 sinus CTs ordered by non-ENT providers, 167 ESS with imaging guidance (4.5%) were ultimately performed and did not require a new CT for intraoperative navigation because of the use of the universal CT protocol.

The annual average per capita effective radiation dose from medical procedures in the United States increased sixfold between 1980 and 2006, from 0.53 to 3.0 mSv compared with background environmental radiation exposure of 2.4 mSv.22. The presented data were derived from an integrated multispecialty academic practice. This approach can reduce health care expenditures and patient radiation exposure. Kanai K, Okano M, Haruna T, Higaki T, Omichi R, Makihara SI, et al. [QxMD MEDLINE Link]. In applying these prices to the 596 ESS cases that did not require a repeated preoperative sinus CT because of the universal sinus CT protocol, total saving was estimated as $142,162, which translated to $147,628 when adjusted for inflation. [2] We have also studied the use of fluoroscopy for this purpose. 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.
