常规X线头颅平片可提供一个完整的、直观的耳蜗内电极的图像,因而主要用于人工电子耳蜗术(cochlear implantation,CI)后的评价。我院常用的拍摄体位为耳蜗式,投照方法是病人俯卧,面部贴于检查床,头颅矢状面与检查床成50°~53°夹角,两下眶耳线垂直于胶片,X线从健侧枕后方经患侧 Conventional X-ray skull radiographs provide a complete and intuitive picture of the intra-cochlear electrodes and are therefore primarily used in the evaluation of artificial cochlear implantation (CI). Our hospital commonly used position for the cochlea, projection method is the patient prone, the face affixed to the examination bed, the head of the sagittal plane and the examination bed into a 50 ° ~ 53 ° angle, two orbital ear perpendicular to the film, X-ray From the contralateral pillow after the affected side
