Personalized care in the context of cochlear implantation is becoming increasingly important. Choosing the right electrode could improve speech understanding. The measurement of the cochlear length plays an important role: preoperatively, in order to select a suitable electrode length; postoperatively, on the one hand to check the correct electrode position, on the other hand to enable anatomically based fitting of the electrode contacts. Of the various possible localizations of the CDL measurements within the cochlear turns, the one on the organ of Corti (CDL) is the most frequently used and clinically most important. In the CDL measurement, a direct and indirect evaluation can be distinguished. There is also the possibility of reconstructing and measuring the CDL in 3D and calculating it mathematically, e.g. using spiral equations. In this context, measurements based on radiological imaging are gaining increasing importance. Therefore, if there is the possibility of performing higher-resolution imaging, this should be strived preoperatively in order to enable the most precise possible procedure and thus a good outcome. Otological planning software can help to create an interface between new findings regarding CDL measurement and higher-resolution imaging for an individualized cochlear implantation.
在人工耳蜗植入背景下的个性化护理正变得越来越重要。选择合适的电极可改善言语理解。耳蜗长度的测量起着重要作用：术前，用于选择合适的电极长度；术后，一方面用于检查电极位置是否正确，另一方面用于实现基于解剖结构的电极触点适配。在耳蜗各圈中进行耳蜗直径长度（CDL）测量的各种可能定位方法中，在柯蒂氏器上进行的测量（CDL）是最常用且临床上最重要的。在CDL测量中，可以区分直接评估和间接评估。也有可能以三维方式重建和测量CDL并进行数学计算，例如使用螺旋方程。在这种情况下，基于放射成像的测量正变得越来越重要。因此，如果有可能进行更高分辨率的成像，术前应努力争取，以便实现尽可能精确的操作并从而获得良好的结果。耳科规划软件有助于在关于CDL测量的新发现与用于个性化人工耳蜗植入的更高分辨率成像之间建立接口。
