Considerable attention has been directed toward analysis of paranasal sinus anatomy through coronal plane computerized tomographic (CT) imaging in this age of functional endoscopic sinus surgery.Recently, it has become apparent that anatomic variations are also evident on CT analysis of patients.Subtle anatomic features can now be imaged through CT, with a level of clarity previously not afforded by standard sinus radiographs.1 The key to a successful endoscopic sinus surgery dorisvale station for sale is the proper identification of landmarks, and intelligent decision-making should there be any doubts as to what moen finney structure lies ahead.
The middle turbinate is the main landmark in the region and should be preserved if possible.Attention to the limits of the middle turbinate landmark is one of the keys to uncomplicated surgery.2 The presence of a retroverted uncinate process, wherein the uncinate process ( rather than the middle turbinate) is the first bone to encountered, can be misleading to the rhinologic surgeon and lead to inadequate surgery.Familiarity with anatomic variations such as the retroverted uncinate process should increase the safety and effectiveness of functional endoscopic sinus surgery.
