The paper deals with three boys suffering from a mixed hearing loss. They were all referred to tomography of the temporal bones in order to find some middle ear malformation amenable to surgery. The tomograms revealed identical malformations of the inner ear; the lumen of the labyrinth are found irregularly dilated and the internal acoustic meatus is widened. Its course in the lateral end is abnormal with a downwards turn towards the basal coil of the cochlea. Explorative tympanotomy in one of the patients revealed a severe otoliquorrhea during an attempt to perform a stapedectomy, and this may serve as a warning against operation in patients presenting the mentioned tomographic changes which, once seen, are easily recognized.
本文研究了三名患有混合性听力损失的男孩。他们都接受了颞骨断层扫描，以寻找一些适合手术治疗的中耳畸形。断层扫描显示内耳存在相同的畸形；发现迷路腔不规则扩张，内耳道增宽。其在外侧端的走行异常，向下转向耳蜗的基底圈。其中一名患者的探查性鼓室切开术显示，在尝试进行镫骨切除术时出现了严重的耳漏，这可能是对呈现上述断层扫描变化的患者进行手术的一个警示，一旦出现这些变化，很容易识别。
