Let us know what protocols you have issues with and we will address them. Immuno-compromised patients are at increased risk for complicated bacterial or fungal infections. During the study period, 876 ESS cases were performed, and 596 used imaging guidance (68.0%). This technology is beneficial in cases that involve both otolaryngologists and neurosurgeons, as one image-guidance system can be used for navigation. 4 0 obj /Contents 8 0 R>> 8600 Rockville Pike Noncontrast coronal computed tomographic (CT) images can define the nasal anatomy much more precisely. The following are examples of critical points when computer guidance is of greatest assistance during surgery: Delineating a skull base contour during a revision procedure, Distinguishing smooth-walled peripheral cells from surrounding landmarks. "U|7QEHDIYcXm2>@!4^k, 7tWD~ Outpatient Diagnostic & Screening Radiology Services. Persistent or progressive symptoms after maximal medical therapy, in combination with CT evidence of paranasal sinus disease, should prompt referral. The CT images and direct views from the endoscope are visualized throughout the procedure.

[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). Rhinosinusitis is a common disease that imposes a large economic burden on the health care system,1 with the direct costs for sinus computed tomography (CT) being a significant contributor. [13]. The benefit of a common sinus CT protocol would be negated if a patient proceeded with ESS at an external facility that may have required a repeated preoperative CT. The development and rapidly growing popularity of image-guided surgery in sinus surgery are directly attributable to the risks of such disruptions. Ann Coll Surg HK. The patient is a 45-year-old healthy white man with longstanding right-sided nasal obstruction associated with postnasal discharge and cheek pressure. We will keep you up to date on these new developments as we expand this section. [12] although recent developments alleviated the latter limitation.

Karen H Calhoun, MD, FACS, FAAOA Professor, Department of Otolaryngology-Head and Neck Surgery, Ohio State University College of Medicine 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. 2007 Feb. 136(2):268-73. 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. 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.
