将30例(58侧)慢性鼻窦炎鼻息肉患者行内窥镜鼻窦手术前的CT检查结果和术中所见进行比较。结果表明,CT检查能良好地显示鼻腔鼻窦的病变范围和程度,与术中所见的符合率高。根据CT所示筛房骨化情况可将筛窦分为空泡型、骨质增生型和蜂窝型,并以此作为麻醉方式选择、估计术中难度等的参考依据。可见,CT是内窥镜鼻窦手术前必不可少的检查手段。
Thirty patients (58 sides) of chronic sinusitis and nasal polyps patients underwent endoscopic sinus surgery before CT findings and intraoperative findings were compared. The results show that, CT examination can well show the extent and extent of nasal sinus lesions, and the intraoperative findings consistent with the high rate. According to CT screening of ossification of the ethmoid sinus can be divided into vacuolar, hyperplastic and honeycomb type, and as a choice of anesthesia, intraoperative difficulty in estimating the reference. Visible, CT is an essential examination before endoscopic sinus surgery.
