X-ray:

• Radiography is most useful in evaluating the maxillary, sphenoidal, and frontal sinuses;
• We will find: opacification or veiling of the interior of the paranasal cavity;
• Frontal sinus with secretion, and this makes the X-ray veiled, therefore, the structures are more radiopaque due to the secretion.
