説明

Accurate demonstration of normal and pathologic anatomies of the facial nerve was investigated using high resolution computed tomography, CT/T 8800. In the preliminary experiment, coronal and horizontal scannings were made of dry bone, infusing yttrium oxide (Y2O3) into the Fallopian canal and painting the stapes with yttrium oxide. Visualization of the Fallopian canal on coronal scanning was better demonstrated than on horizontal scanning. In the presence of a disease suspected to be facial neurinoma, high resolution CT has some merit in demonstrating bone changes in the Fallopian canal, and this target imaging is an effective means of studying patients with facial nerve disorders.
