Move the forehead, nose tip and cheekbones closer to the cassette, so that the sagittal plane of the skull forms an angle of 45o with the cassette, and the orbital line of the cassette is perpendicular to the cassette. The center line is tilted to the head side at an angle of12o, aiming at the intersection point of the line connecting the occipital protuberance and the external auditory canal on the side to be examined, and shooting is carried out at the center of the cassette. Use the general position. It is valuable for the diagnosis of inner ear lesions and acoustic neuroma.
