The author has evaluated the panoramic image clarity of the midfacial anatomic
structures in dry skull according to the skull position. The radiopaque markers were
attached to the anatomic structures: infraorbial rim, upper and lower borders of
zygomatic arch, pterygomaxillary fissure, lateral pterygoid plate, pyriform aperture of
nasal cavity, lateral wall of maxilla, orbital floor, infraorbital foramen, and nasal floor.
Position of the skull were divided into four groups. standard, 25§® forward, chin-down,
chin-up position.
The results were as follows.
1. The pyriform aperture of nasal cavity, lateral wall of the maxilla, orbital floor,
infraorbital foramen and nasal floor did not cast any discernible image.
2. Nearly all images of midfacial structures were blurred in the chin-up position.
3. The forward position provided good visualization of the maxillary sinus.
4. The chin-down position provided good visualization of the zygomatic arch,
pterygomaxillary fissue, and lateral pterygoid plate.
