Multislice computed tomography (MSCT) virtual endoscopy was useful in evaluating mainly post-traumatic and postoperative cases. In other pathological conditions axial images and MPR reformations were most useful.
Evaluation of cross-sectional images, multiplanar 2-D reformations, 3-D reconstructions and virtual endoscopy (VE) in assessment of the middle ear in inflammatory diseases, trauma, otosclerosis and tumours. Comparison of each method and correlation with surgical findings.
Investigations were carried out in 80 patients with middle ear pathology. In each case MSCT of the petrous bone was performed. In addition to cross-sectional native scans, frontal and sagittal images were achieved using MPR reconstructions. 3-D volume rendering (VR) and VE images were also generated. The value of native scans information, 2-D, 3-D reconstructions and VE of the tympanic cavity structures was assessed in comparison to intraoperative findings.
MPR reconstructions were most useful in the assessment of skull base trauma, skull base tumours and in cases of chronic middle ear inflammation. Highly vascularized tumours, disruption of ossicular chain and stapes prosthesis were best evaluated on 3-D reconstructions. Axial images proved to be the best for otosclerosis interpretation.
多层螺旋计算机断层扫描（MSCT）虚拟内镜主要用于评估创伤后和术后病例。在其他病理情况下，轴位图像和多平面重组（MPR）最为有用。
评估横断面图像、二维多平面重组、三维重建和虚拟内镜（VE）在评估中耳炎性疾病、创伤、耳硬化症和肿瘤中的应用。比较每种方法并与手术结果进行相关性分析。
对80例中耳病变患者进行了研究。对每例患者均进行了颞骨MSCT检查。除横断面平扫外，还使用MPR重建获得了冠状位和矢状位图像。还生成了三维容积再现（VR）和VE图像。将鼓室结构的平扫信息、二维、三维重建及VE与术中结果进行比较，评估其价值。
MPR重建在评估颅底创伤、颅底肿瘤及慢性中耳炎症病例中最有用。三维重建对高血运肿瘤、听骨链中断和人工镫骨的评估最佳。轴位图像被证明是解释耳硬化症的最佳图像。
