In a retrospective study 170 computed tomographies recorded in patients with chronic sinus disease were evaluated. The extent of sinus disease and the involvement of the different paranasal sinuses were well seen. Up to now 50 patients have undergone surgical treatment. The coincidence of the preoperative CT with the intraoperative findings was about 90%. Anatomic particularities of the paranasal sinus in an individual patient may predispose to recurrent sinusitis or mean there is an increased risk of intraoperative complications. The main risk factors are a far lateral location of the posterior ethmoid cells (28.8%), a much lower position of the cribriform plate in comparison to the ethmoid roof (11.8%), and extensive lateral aeration of the sphenoidal sinus (1.2%). All patients should undergo CT scanning in coronal and axial planes prior to endonasal sinus surgery. This gives a guide for detection of inflammatory lesions and anatomic variations or anomalies, thus making it possible to prevent intraoperative complications.
在一项回顾性研究中，对170例慢性鼻窦疾病患者的计算机断层扫描记录进行了评估。鼻窦疾病的范围以及不同鼻窦的受累情况清晰可见。到目前为止，已有50例患者接受了手术治疗。术前CT与术中发现的吻合率约为90%。个体患者鼻窦的解剖特殊性可能易患复发性鼻窦炎，或意味着术中并发症风险增加。主要危险因素是后筛窦细胞的远外侧位置（28.8%）、筛板相对于筛窦顶的位置低得多（11.8%）以及蝶窦广泛的外侧气化（1.2%）。所有患者在鼻内鼻窦手术前均应进行冠状面和轴位面的CT扫描。这为检测炎症病变以及解剖变异或异常提供了指导，从而有可能预防术中并发症。
