To explore ways of evaluating morphological information of cochlea electrode in post cochlear implantation patients, and so as to make sure its value of clinical usage.A series of 52 patients who were diagnosed as severe to profound sensorineural hearing loss and received cochlear implantation were admitted. All the patients had cone-beam CT scanning of the operated side 1 or 2 days after operation. The software of NNT Viewer was used to proceed original DICOM data of CBCT scanning in order to evaluate the morphological information. A comparative study in recognizing the numbers of anatomic structures was carried out between CBCT and X-ray.All the 52 patients successfully received cochlear implantation as well as CBCT scanning.The cochlear implantation was implanted bilaterally at the same time in 3 patients, left side implantation in 13 patients and 36 cases in right side. There are four ways of evaluating the morphological information of electrode in cochlea post-operatively, including mode of Panorex, mode of MPR, mode of 3D-Ceph and 3D-Bone. A comprehensive evaluation can be achieved by the using of these four methods. The numbers of anatomic structures distinguished by CBCT is far more than X-ray.The evaluating methods of CBCT scanning is flexible and diverse, the CBCT scanning have unique values in clinical usage.
探讨人工耳蜗植入术后患者耳蜗电极形态学信息的评估方法，以确定其临床应用价值。收治52例诊断为重度至极重度感音神经性听力损失并接受人工耳蜗植入的患者。所有患者在术后1或2天对术侧进行锥形束CT扫描。使用NNT Viewer软件对CBCT扫描的原始DICOM数据进行处理，以评估形态学信息。对CBCT和X线在识别解剖结构数量方面进行了对比研究。52例患者均成功接受人工耳蜗植入及CBCT扫描。3例患者同期双侧植入人工耳蜗，13例左侧植入，36例右侧植入。术后评估耳蜗电极形态学信息有四种方式，包括全景片模式、多平面重组模式、三维头影测量模式和三维骨模式。综合运用这四种方法可实现全面评估。CBCT分辨出的解剖结构数量远多于X线。CBCT扫描评估方法灵活多样，在临床应用中有独特价值。
