内听道位于颞骨岩部内,为前庭蜗神经从内耳通入颅内的骨性通道。当临床有听力下降须排除如听神经瘤等病变时,就常要作该部位的拍片检查。虽然近年有了先进的MRI和CT等检查手段,但X线平片仍是常规的检查方法。我们最近对内听道拍片采用反斯氏位进行投照的探索,显示影像效果较优良,投照操作较为快捷方便,现将体会介绍如下: Internal auditory canal is located in the temporal bone rock department, the vestibular cochlear nerve access from the inner ear intracranial bone channel. When clinical hearing loss to be ruled out, such as acoustic neuroma and other lesions, often for the site filming. Although in recent years with advanced MRI and CT and other inspection methods, but X-ray is still routine inspection methods. Our recent exploration of intra-auditory film using anti-Si bits to make the projection shows that the image effect is better, the projection operation is quick and easy, we will experience the introduction as follows:
