Особенности диагностики изолированных аномалий среднего уха

Abstract

In this article, we present the role of 3D CT modeling in the assessment of diagnostics and surgical treatment of isolated middle ear anomalies. Three-dimensional visualization of the middle ear facilitates the understanding of the patient’s anatomy. To demonstrate the advantages of combining both approaches, we performed computed tomography (CT) in two normal patients and 40 different anomalies of the middle ear, and the 3D-models were correlated with CT scan cross sections. Reconstructed CT data sets were obtained using a multispiral CT. In all cases, the authors used the software RadiAnt DICOM Viewer and Vidar Dicom Viewer to create 3D-models of the middle ear. Such tools are used to review and analyze DICOM-PACS medical images. Three-dimensional models of individual anatomical structures were displayed in various colors. This approach may be clinically applicable to obtain a three-dimensional understanding of the patient’s anatomy using the models as a reference because creating three-dimensional models can be extremely time-consuming. Moreover, it can help radiologists and otolaryngologists to evaluate 2D-slices by adding correct 3D-information that otherwise would need mental integration. The method may be applied for X-Ray diagnostics, surgical planning and, especially, for training.
