This report presents a new sign of ossicular dislocation utilizing high resolution computed tomography of the temporal bone. In the case of lateral dislocation of the incus, a "Y" shaped configuration (Y sign) of the malleoincudal complex is seen in the coronal views even though the axial views present a normal "ice cream cone" configurations.
本报告介绍了一种利用颞骨高分辨率计算机断层扫描诊断听小骨脱位的新征象。在砧骨外侧脱位的情况下,即使轴位视图显示正常的“冰淇淋蛋筒”形态,在冠状视图中也可看到锤砧复合体呈“Y”形结构(Y征)。
