BACKGROUND The purpose of this study is to demonstrate the advantages of 3D volume rendering in postoperative control of implants placement compared to high-resolution computed tomography (HRCT). CASE REPORT We describe 3 patients who underwent HRCT study with and without 3D volume rendering after surgery for cochlear implantation. In 2 patients, the traditional HRCT showed a suspected malposition of the array, excluded only by the rendering reconstruction. In the other patient, thanks to the 3D rendering, we were able to identify the complete migration of the array out of the cochlea and the tip of the electrode near the opening of internal auditory canal, while the traditional images showed only that the array was not rolled up inside the cochlea. CONCLUSIONS HRCT showed complex anatomic structures of the inner ear and contents of the middle ear cavity. The volume rendering, in the postoperative control, generates interactive 3D images of the cochlear implant, facilitating a clearer representation of the topographic complex of the cochlea, giving more detailed diagnostic information than the HRCT.
背景 本研究的目的是证明与高分辨率计算机断层扫描（HRCT）相比，三维容积再现技术在人工耳蜗植入术后植入物位置控制方面的优势。病例报告 我们描述了3例人工耳蜗植入术后接受HRCT检查（包括有和没有三维容积再现技术）的患者。在2例患者中，传统的HRCT显示电极阵列疑似位置不当，仅通过容积再现重建排除。在另1例患者中，借助三维容积再现技术，我们能够确定电极阵列完全移出耳蜗，电极尖端靠近内耳道开口，而传统图像仅显示电极阵列未在耳蜗内卷曲。结论 HRCT显示了内耳的复杂解剖结构和中耳腔内容物。在术后检查中，容积再现技术生成人工耳蜗的交互式三维图像，有助于更清晰地呈现耳蜗的地形复合体，比HRCT提供更详细的诊断信息。
