Caldwell's view

Caldwell's View is a radiographic view used in the field of radiology to visualize the paranasal sinuses, specifically the frontal sinus and ethmoid sinus. Named after the American radiologist, Arthur M. Caldwell, this view is commonly used in the diagnosis of sinusitis and other sinus-related conditions.

Technique

The Caldwell's view is performed with the patient's forehead and nose in contact with the image receptor. The central ray is angled 15 degrees caudally (downwards) and centered to exit at the level of the nasion. This positioning allows for a clear view of the frontal and ethmoid sinuses.

Indications

Caldwell's view is primarily indicated in cases of suspected sinusitis, a common condition characterized by inflammation of the sinuses. It can also be used to detect other abnormalities in the sinuses such as polyps, tumors, and fractures.

Limitations

While Caldwell's view provides a detailed image of the frontal and ethmoid sinuses, it is less effective in visualizing the sphenoid sinus and maxillary sinus. For these sinuses, other views such as the Waters' view may be more appropriate.
