The CT studies of 198 consecutive patients with chronic sinusitis were reviewed retrospectively. CT was normal in 47 patients (23.7%). In 151 patients one or many cavities showed abnormalities. In 69 cases (34.9%), the lesions affected one or two sinuses, in 35 cases (17.7%) three to six cavities were abnormal, whereas in 47 cases (23.7%), more than six cavities were abnormal. In 87 cases (57.6%), lesions were observed both in large cavities and ethmoid cells, whereas they were selectively localized in large cavities in 55 cases (36.4%), or in ethmoid cells in 9 cases (6%). Abnormalities were observed in the maxillary sinus in 137 patients (69.2%), in the ethmoid in 96 patients (48.5%), in the frontal sinus in 51 patients (25.8%), and in the sphenoid sinus in 28 patients (14.1%). The most frequent abnormality was hypertrophic mucosa, which was visible in 275 cavities. These results were compared with date of the literature.
对198例慢性鼻窦炎患者的CT研究进行了回顾性分析。47例患者（23.7%）CT表现正常。151例患者中一个或多个鼻窦腔显示异常。69例（34.9%）病变累及一个或两个鼻窦，35例（17.7%）三个至六个鼻窦腔异常，而47例（23.7%）六个以上鼻窦腔异常。87例（57.6%）在大鼻窦腔和筛窦均观察到病变，55例（36.4%）病变仅局限于大鼻窦腔，9例（6%）仅局限于筛窦。137例患者（69.2%）上颌窦有异常，96例（48.5%）筛窦有异常，51例（25.8%）额窦有异常，28例（14.1%）蝶窦有异常。最常见的异常是黏膜肥厚，在275个鼻窦腔中可见。将这些结果与文献数据进行了比较。
