What are Coriolis position, Warburg position and mastoid Xu position?

Waters position and Cald well position are the most commonly used projection positions for sinus examination. Warburg position can observe the frontal sinus, ethmoid sinus and maxillary sinus, and Coriolis position can better observe the frontal sinus and ethmoid sinus.

Precautions:

1. When shooting with a filter, the shooting distance should be controlled within the focal length range of the filter grid.

2. In order to keep the skull stable, when posing, the patient clenched his fist on the opposite side to support the mandible.

3, conventional frame photography, bilateral mastoid projection in the same photo.

Key points of photography:

1. The client is prone on the photographic bed, with the median sagittal plane perpendicular to the bed surface and coincident with the center line of the bed surface.

2. The forehead and the tip of the nose are placed on the bed surface, the mandible is adducted, and the auditory canthus line is perpendicular to the bed surface.

3. The cassette is placed on the filter disk or flat on the photographic bed (a fixed grid is placed on it to prevent Compton effect from increasing the gray scale of the film), and its long axis is parallel to the center line of the bed.

4. Align the nasal root with the center of the film.

The patient is prone on the photographic table, with his head in a standard lateral position. The auricle of the tested side is folded forward and clings to the cassette, and the external ear hole is placed in the center of the cassette. The mandible is slightly retracted, so that the auditory orbital line is perpendicular to the edge of the cassette.
