This short monograph reviews the author's experience in the diagnosis of blowout fractures of the orbit. The bulk of the book is devoted to orbitography and hypocycloid tomography in the diagnosis of orbital floor fractures. The reproductions of the radiographs are, unfortunately, of such poor quality that many of the findings cannot be appreciated.
The historical review has missed the descriptions by Dr. Raymond Pfeiffer in 1941 and 1943 in which he clearly outlined the mechanism of what has come to be known as the "blow-out" fracture. In the preparation of tomograms, technical factors as focal spot size, fine resolution screens, patient immobility, tight coning, and mechanical sophistication of the unit are as important as the blurring pattern in making pictures of high quality. The current interest in hypocycloid blurring ignores the satisfactory results that high quality linear tomography can produce.
There is an excellent short chapter by Dr.
