Although air-fluid levels and complete opacification of a sinus are more specific for sinusitis, they are only seen in 60 percent of cases. Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2).

This CT protocol section provides a reference and useful resource to help you achieve the highest level of quality in your CT examinations. Three aspects of direct coronal imaging of the paranasal sinuses were investigated: (1) preparation of the patient prior to the examination; (2) technical factors of the CT study, including positioning of the patient, optimal coronal angle, slice thickness, and CT exposure factors; and (3) data display. 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.

Newer methods are available for automated registration; for instance, small cranial pin transmitters designed to replace the more bulky headsets currently in use may have exceptional benefit in open skull base or orbital cases. What would be the reason for this protocol? Blackwell DL, Lucas JW, Clarke TC. Two pulses of oral steroids produced a prolonged response that was again only temporary.
[QxMD MEDLINE Link]. Clearing the operative field of blood and debris and then using either a tracking pointer or a tracking curved suction to elucidate anatomicquestions is most prudent for the surgeon, who may then proceed safely with the next step of surgery. There are several manufacturers now including InstaTrak by GE,, BrainLAB, Medtronic (LandmarX) Fusion, and Stryker iNtellect ENT . Not only did this make it easier to reach a consensus on CT imaging protocols, but it also increased the likelihood that a patient who received a sinus CT and ultimately needed ESS would have this performed at the same institution.

Rosenfeld RM, Piccirillo JF, Chandrasekhar SS, et al. 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.
