ReviewCurrent indications and techniques in evaluating inflammatory disease and neoplasia of the sinonasal cavities.
Imaging strategies of the sinonasal cavities have undergone extensive revision over the last 5-year period. The traditional imaging examination of the paranasal sinuses, plain film radiography, does reasonably well in diagnosing maxillary, frontal, and sphenoid sinusitis. However, it less reliable in depicting abnormalities in the ethmoid sinuses, the most common area first affected with inflammatory disease. ⋯ In addition to developing an imaging algorithm to provide the information affecting clinical decision making, we detail the specific imaging techniques necessary accurately to obtain that information. We also review the specific concerns about imaging patients in the intensive care unit and touch on several emerging imaging techniques. The imaging workup in pediatric patients and patients with congenital anomalies is beyond the scope of this review.
