An X-Ray of the Sinus is a simple and quick imaging test that captures the frontal sinuses, helping diagnose sinus infections, inflammation, blockages, or structural abnormalities. It is commonly used to investigate sinusitis, facial pain, nasal congestion, or headaches related to sinus issues. The test provides a clear image of the air-filled sinus cavities, assisting doctors in identifying fluid buildup or thickened sinus walls.
