Recent advances in "functional" endoscopic surgical techniques require the radiologist to understand the anatomy and pathophysiology of the nose and paranasal sinuses as well as their normal and abnormal CT patterns. Endoscopy and CT are complementary procedures, but in the evaluation of the extent of chronic inflammation and in the demonstration of possible associated local and regional complications, the latter method has become the imaging technique of choice, providing a detailed map for the functional sinus surgeon and replacing plain radiography. The authors reviewed a personal series of 322 coronal thin-slice CT examinations of the paranasal sinuses relative to 169 patients with chronic or acute sinusitis and polyposis. The main CT findings of sinusitis (mucosal thickening, fluid retention, mucous cysts, bone alterations, mucoceles and polyposis) and their complications are reported. Finally, ostiomeatal conditions are considered, particularly the obstruction of ducts and ostia which provide aeration and mucous clearance from the paranasal sinuses.
“功能性”内镜手术技术的最新进展要求放射科医生了解鼻和鼻窦的解剖结构、病理生理学以及它们正常和异常的CT表现。内镜检查和CT是互补的检查方法，但在评估慢性炎症的范围以及显示可能相关的局部和区域并发症方面，后一种方法已成为首选的成像技术，为功能性鼻窦外科医生提供详细的图谱，并取代了平片摄影。作者回顾了针对169例慢性或急性鼻窦炎及鼻息肉患者的322例鼻窦冠状位薄层CT检查的个人系列病例。报告了鼻窦炎的主要CT表现（黏膜增厚、积液、黏液囊肿、骨质改变、黏液囊肿和鼻息肉）及其并发症。最后，考虑了窦口鼻道情况，特别是提供鼻窦通气和黏液清除的管道和开口的阻塞。
