Question

Water’s view is used to obtain diagnostic information of:

• A. Maxillary sinus
• B. Ethmoidal sinuses
• C. Frontal sinus
• D. Sphenoid sinus

Answer 1

The Correct Option is A

Water’s view, also known as the occipitomental view, is a specific type of X-ray examination used in radiodiagnosis to assess various paranasal sinuses. This view provides critical diagnostic information used primarily to evaluate:

Maxillary sinus

Explanation:

The Water’s view is taken by positioning the patient’s head in such a way that the occipito-mental line is approximately 37 degrees to the gas-permeable surface. This positioning allows for an unobstructed view of the paranasal sinuses, particularly the maxillary sinuses. In clinical practice, this view is optimal for detecting:

• Maxillary sinusitis: Water's view effectively reveals fluid levels within the maxillary sinuses, which may indicate infection or other sinus conditions.
• Facial fractures: It helps in visualizing fractures that affect the floor of the orbit and maxillary sinus walls.

Water's view is less effective for directly visualizing the ethmoidal, frontal, and sphenoid sinuses due to their anatomical positions and orientations within the skull.
