The aim of the study was to undertake a controlled prospective evaluation of high resolution computerized tomography in the pre-operative diagnosis of labyrinthine fistulae. Fifty consecutive patients with chronic suppurative otitis media were scanned prior to surgery, using a Siemens DRI scanner. The radiological predictions were then compared with the surgical findings. Five patients had labyrinthine erosions and these were predicted in 4 out of the 5 (80%). The one erosion that escaped radiological detection was less than 2 mm in length. The study shows that high resolution computerized tomography is a highly accurate method for demonstrating pre-operatively all but the smallest fistulae.
本研究的目的是对高分辨率计算机断层扫描在迷路瘘管术前诊断中的应用进行对照性前瞻性评估。使用西门子DRI扫描仪对50例连续的慢性化脓性中耳炎患者在手术前进行扫描。然后将放射学预测结果与手术发现进行比较。5例患者存在迷路侵蚀，其中4例（80%）在术前被预测到。唯一未被放射学检测到的侵蚀长度小于2毫米。该研究表明，高分辨率计算机断层扫描是一种高度准确的方法，可在术前显示除最小瘘管外的所有瘘管。
