The center ray lies in the plane through the ear so that the ray hits the point 70mm from the opposite ear, the angle is about 25 to 30 degrees down to the foot and goes to the side of the ear on the side to be photographed. Take Schuller X-rays twice at the time of opening and closing the mouth to investigate the condition of the temporomandibular joint.
5. Processing results after X-ray Schuller
If the results are normal, the cells and their septum can be clearly seen.
If there is pathology, some characteristics are as follows:
The septum is opaque and the septum is not clear, the patient has acute mastoiditis. If the septum is opaque but the septum is absent, then chronic mastoiditis is present. On the background of the mastoid bone is blurred, with bright areas, surrounded by dark edges, looking like clouds, thinking of cholesteatoma lesions in chronic mastoiditis This Schuller X-ray technique has no complications. However, some errors may cause the technique to be re-implemented such as: the patient does not remain motionless during the imaging process, the joint image is not clearly revealed,...

Adjust the patient's face to slightly bow. Choose the center ray
Then 1: Shine at an angle so that the vertical line passes through the outer edge of the eye socket 2cm of the patient and the horizontal line passes through the temporal fossa and the rim of the ear. Central ray to the outer end of the brow arch.
2: Carry out occipital fixation and rotate the head slowly to the side without X-ray so that the central ray shines into the temporal fossa on the right side to be photographed (a reasonable distance is 1/3 between the line connecting the tail of the eye and the center of the eye). Helix).
Successful imaging results are when we can clearly see mastoid cells in the middle of the film and fully see paracavernous cells, extra-vestibular semicircular canal, and superior semicircular canal.
X-ray of Chaussé III position is a simple technique and there are no complications. However, if during the imaging process, the patient does not lie still, the joint image will not be clearly revealed, so it will have to be retaken.
