Method of obtaining Caldwell's view

Caldwell's view (or Occipitofrontal view) is a radiographic view of the skull where the X-ray plate is perpendicular to the orbitomeatal line. The rays pass from behind the head and are angled at 15-20° to the radiographic plate. It is commonly used to get better view of the ethmoid and frontal sinuses.[1] It is named after the noted American radiologist Eugene W. Caldwell, who described it in 1907.[2][3]

Structures seen

Possible observations

Pathology Observation
Normal
  • Different pneumatisation patterns of frontal sinus are observed in population.
  • The frontal sinuses can be asymmetric in normal individual.
  • Usually, frontal sinus shows radiolucent shadow and individual cells are made out, giving it a scalloping or clove-like appearance.
Chronic frontal sinusitis
  • Increased frontal sinus opacity.
  • Normal scalloping absent.
Osteoma
  • Marked radiopacity is seen. (Denser than bone)
Erythroblastic anemia
