With the relatively recent advent of computed tomography (CT), a truly major advance in radiology, many diagnostic puzzles have become easy to solve. First applied to the diagnosis of neurologic disease, and quickly recognized as indispensable, CT was rapidly incorporated into the armamentarium of almost every medical and surgical practitioner. Utilization of CT to solve diagnostic dilemmas has even been done by such unexpected specialists as medical anthropolo-gists. By scanning an ancient Egyptian mummy case, they saw exquisite anatomic detail of the mummy within, thereby avoiding unnecessary mutilation of the beautiful cartonage." For the plastic surgeon, too, with his wide spectrum of interests, CT has proven increasingly helpful in facilitating diagnosis and therapy. CT surpasses many of the limitations of conventional radiographic techniques. A cross section of the body is depicted with accuracy, unencumbered by superimposed shadows from surrounding tissue. By presenting a series of contig-uous cross sections, CT allows the viewer, with-out excessively taxing his or her imagination, to reconstruct a readily comprehensible three-dimensional image of the subject.
