对儿童双侧重度耳聋，近几年使用有最佳语言分辨力的复杂的多通道耳蜗植入装置者渐增多。由于耳聋儿童存在部分或完全性耳聋管胜闭塞，常给手术造成相当大困难。术前充分评估耳蜗情况就显得十分重要。就耳蜗术前的高分辨CT扫描与手术所见进行对照，以探讨CT在评估耳蜗情况的可
Bilateral severe deafness in children has increased in recent years with the use of complex multi-channel cochlear implants that have the best speech resolution. Because of the partial or complete deafness of deaf children, the prevalence of occlusion and obliteration often causes considerable difficulties in surgery. Preoperative assessment of the cochlear situation is very important. Cochlear high-resolution CT scan before surgery and surgical findings were compared to explore CT in the assessment of cochlear conditions may be
