IN A PREVIOUS report1 an alteration of the frontal sinus wall which occurred frequently in paranasal cancer was discussed. This was observed in 35% of our irradiated patients. The alteration appears on x-ray films as blurring, demineralization, and/or condensation of the upper and posterior wall of the sinus. It is not surprising to find similar alterations developing in the wall of the sphenoid sinus also.
Our related experiences are limited for various reasons. The films of our irradiated patients were reviewed. In the early period the sphenoid sinuses were not examined routinely. Later the film technique was aimed at visualizing the soft tissue alterations rather than the finer bony details. Therefore, the greatest number of the lateral sinus films and a part of the axial views were not suitable for the present special study of the finer details of the sphenoid sinus outlines. It was especially difficult on
