X射线显微层析成像(Micro-CT)是一种新技术，它可以显示不透明样品的内部结构，具有准组织学性质。在众多潜在的应用中，该技术在耳科中的应用前景非常广阔。Micro-CT似乎非常适合于内耳组织的体外可视化，以及在人工耳蜗植入电极植入过程中评估电极损伤和/或手术插入损伤。该技术可为新型人工耳蜗电极的设计和开发提供极大的帮助，并适用于颞骨研究。Micro-CT的主要优点是样品的制备几乎没有伪影，而且可以沿着电极的整个插入深度评估感兴趣的参数。本文介绍了首次应用Micro-CT显示人颞骨内耳结构的结果，并评价了人工耳蜗术中电极相对于耳内软组织的定位。
X-ray microtomography (micro-CT) is a new technique allowing for visualization of the internal structure of opaque specimens with a quasi-histological quality. Among multiple potential applications, the use of this technique in otology is very promising. Micro-CT appears to be ideally suited for in vitro visualization of the inner ear tissues as well as for evaluation of the electrode damage and/or surgical insertion trauma during implantation of the cochlear implant electrodes. This technique can greatly aid in design and development of new cochlear implant electrodes and is applicable for temporal bone studies. The main advantage of micro-CT is the practically artefact-free preparation of the samples and the possibility of evaluation of the interesting parameters along the whole insertion depth of the electrode. This paper presents the results of the first application of micro-CT for visualization of the inner ear structures in human temporal bones and for evaluation of the surgical positioning of the cochlear implant electrodes relative to the intracochlear soft tissues.
