If palpation of the sinuses suggests sinusitis,transillumination of the frontal and maxillary sinuses should be performed.To evaluate the maxillary sinuses,place the light source under each eye and just above the infraorbital ridge.Ask the patient to open her mouth.Observe the red glow on the hard palate.Healthy sinuses contain air and will light up symmetrically.To evaluate the frontal sinuses,place a strong light source under the bony ridge of the upper orbits.Observe the red glow over the sinuses.The glow on each side is equal,indicating air-filled frontal and maxillary sinuses.An inflamed sinus filled with fluid does not transilluminate.
