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. He was started on intravenous antibiotics and underwent external frontal sinusotomy to decompress the adjacent infected frontal sinus. Consequently, the subset of patients that ultimately needed ESS would not require repetitive imaging. Ku PK-M, Pak MW, van Hasselt CA. CT scans of internal organs, bones, softtissue and blood vessels provide greater clarity and reveal more details than regular x-ray exams. Bones appear white on the xray; soft tissue shows up in shades of gray and air appears black. Verification of accuracy using patient anatomical landmarks.
/Contents 6 0 R>> Usually done without contrast. These localization maneuvers should be performed with diagnostic instruments, not surgical instruments. Otolaryngol Head Neck Surg. In the current study, all the CTs used for ESS were graded as technically adequate, so subjective quality for intraoperative navigation was not negatively impacted.

Bar graph, demonstrating the relative proportions of patients who underwent sinus CT compared with those who subsequently had ESS with imaging guidance based on referring provider specialty; the difference in proportions across the three referring groups was found to be statistically significant (p < 0.0001). Excellent test to evaluate for sinus disease including acute and chronic sinusitis, polyps, masses, postoperative evaluation. "U|7QEHDIYcXm2>@!4^k, 7tWD~ endobj Today, most CTscanners provide data sets compatible with commonly used guidance systems. 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). Outpatient Diagnostic & Screening Radiology Services. To date, in the authors' institution, more than 1000 computer-assisted ESS procedures have been performed over a period of 10 years. The patient was started on a four-week course of broad-spectrum antibiotics in combination with an oral steroid pulse. 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). 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.

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. Screening sinus CT by using either a very low radiation dose or limited anatomic coverage was not in use because of local practice preferences. /Contents 4 0 R>> Franklin JH and Wright ED.
