Objective To discuss a new temporal bone tomography radiographic technique for the assessment of cochlear implantation and its clinic value. Methods Plane radiographs of both the temporal bone tomography and cochlear position tomography were taken on 10 children after cochlear implantation. The numbers of inserted electrodes of both techniques were compared. Results The inserted electrodes were shown clearly in both techniques. There was no difference in the data be-tween the 2 methods and between the operation and radiography outcomes (P>0.05). Conclusion Temporal bone tomography is a new method to evaluate cochlear implants in postoperative patients.%目的:探讨颞骨体层方法对人工耳蜗的显示效果和临床应用价值.方法:对10例人工耳蜗植入术后的患儿同时行颞骨体层术和耳蜗位片的投照,并比较两种方法的植入电极对数.结果:两种方法均能清晰显示人工耳蜗电极的位置及植入电极个数,2组间无明显差异,与手术结果比较亦无明显差异(P>0.05).结论:颞骨体层术可以作为一种新的评价人工耳蜗的X线检查方法.
