To the Editor: I was very much interested in reading Dr. Horner's article entitled "The Technique of Transillumination of the Skull" which appeared in the February, 1962, issue of the Journal. Certainly this simple technique has proved to be of considerable diagnostic aid.
We have found that a very simple modification of this equipment has been very useful to us. Instead of wrapping foam rubber around the flashlight, we have found that the rubber top of a bottle for administration of saline or other fluids works quite well. Attached is a photograph showing this. The rubber top from the saline bottle can simply be taped to the flashlight. The advantages of this are its inexpense and its small size and availability. Another advantage is the fact that the aperture can be enlarged to any size desired.
