Study Notes

Lateral Facial Bones X-Ray Technique

  • For lateral facial bone radiographs, the patient is positioned in the erect position.
  • The x-ray beam's direction is perpendicular to the plane of the image receptor.
  • The image receptor's vertical center is adjusted to be 2.5 cm below the outer corner (canthus) of the eye. This precise positioning is crucial for accurate visualization of the structures being examined.
