<h3>OBSERVATIONS ON THE TRANSILLUMINATION OF THE FRONTAL SINUSES. DR. EDWARD H. CAMPBELL.</h3> This article will appear in a later issue. <h3>DISCUSSION</h3> Dr. Samuel R. Skillern, Jr.: I have never observed the spot which Dr. Campbell refers to on the opposite side. Transillumination of the frontal sinus may fail due to infected supra-orbital cells. Polyps or pus in infected supra-orbital cells prevent transmission of light in the case of a perfectly healthy frontal sinus. Transillumination of a diseased sinus by diffused light under the soft tissues is possible. Roentgenograms are superior to transillumination. If the roentgenogram disagrees with your diagnosis, however, it is probably wrong. With symptoms of frontal sinus disease and transillumination indicating a black frontal sinus, frontal sinus disease exists even if the sinuses are negative by roentgen examination. In one case with symptoms of right frontal sinus involvement, we desired to do a radical operation. Two roentgenologists, independently,
