Caldwell's view
Caldwell's view is a specific type of radiographic imaging technique used primarily in the field of medicine to visualize the paranasal sinuses. This technique is named after the American radiologist Eugene W. Caldwell, who developed it.
Technique[edit | edit source]
Caldwell's view is performed by positioning the patient so that the X-ray beam is directed at a 15-degree angle to the orbitomeatal line. The patient is typically asked to rest their forehead and nose against the X-ray film or detector. This positioning allows for optimal visualization of the frontal sinuses, ethmoid sinuses, and the orbits.
Indications[edit | edit source]
Caldwell's view is commonly indicated for the evaluation of:
- Sinusitis
- Fractures of the facial bones
- Tumors or cysts in the sinuses
- Foreign bodies in the orbits
Interpretation[edit | edit source]
The resulting radiograph from Caldwell's view provides a clear image of the frontal sinuses and the anterior ethmoid sinuses. It is particularly useful for identifying fluid levels, mucosal thickening, and bone destruction.
Advantages[edit | edit source]
- Provides a detailed view of the frontal sinuses and ethmoid sinuses
- Useful for detecting sinusitis and facial fractures
- Non-invasive and relatively quick to perform
Limitations[edit | edit source]
- Limited visualization of the maxillary sinuses and sphenoid sinuses
- May not be suitable for patients who cannot maintain the required position
