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. Otolaryngol Clin North Am. 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. Patient-specific preprocedural rehearsal devices will allow surgeons to add critical annotations and observations to the imaging data set preoperatively. Blackwell DL, Lucas JW, Clarke TC.

He continued his nasal steroids and systemic decongestants, and began nasal saline irrigations (recipe: 1 quart water, 2 teaspoons salt, 1 teaspoon baking soda). Adopting a single universal sinus CT protocol for diagnostic imaging and intraoperative navigation can be an effective means of decreasing cost and radiation exposure. Because of the progression of his headaches, a maxillofacial and head CT scan was obtained, revealing acute sinusitis with frontal epidural abscess (Figure 2). Accessibility 2006 May. endobj 2013 Mar. 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. This is particularly relevant in cases that involve the pituitary and anterior skull base. She also placed me in a preop stage which I thought was unusual as she acted as if nothing looked "weird" upon scoping me Wednesday. During this period, only the new universal sinus CT protocol was available for use regardless of the specialty of the ordering provider. A list of national and international resources and hotlines to help connect you to needed health and medical services. As such, their conclusion was that the primary limiting factor for radiation dose reduction is the surgeon's willingness to accept impaired image quality. Fuoco G, Chiodo A, Smith O, et al. This technology is beneficial in cases that involve both otolaryngologists and neurosurgeons, as one image-guidance system can be used for navigation. To provide the best experiences, we use technologies like cookies to store and/or access device information.
