Overview
The Caldwell projection images the frontal sinuses orbital rims and nasal bones with the forehead against the detector. The beam is angled caudally to project the petrous ridges below the orbits. This view complements Waters and lateral projections for facial trauma evaluation.
Technique
Position the patient with the forehead and nose against the detector and angle the tube approximately 15 degrees caudad. Center the detector to the mid face and use appropriate exposure. Immobilize the head to minimize motion.
Clinical Indications
Caldwell view is indicated for frontal sinus trauma suspected orbital rim fracture and nasal bone assessment. It aids in detecting sinus fluid levels and anterior table fractures. CT is preferred for complex facial fractures and surgical planning.
Image Assessment
Evaluate frontal sinus integrity orbital rim continuity and nasal bone alignment. Look for air fluid levels and displaced fractures. Recommend CT for definitive assessment when indicated.
