This atlas of temporal bone anatomy by Valvassori and Buckingham is a valuable addition to the literature on pluridirectional tomography of the petrous bone. One-millimeter thick hypocycloidal tomograms of temporal bone specimens are compared with 2-mm thick anatomic macrosections of the same specimen sectioned in the identical plane. Specimens are examined in the horizontal, coronal, semiaxial, axial, sagittal, and longitudinal projections. Each macrosection is radiographed, thus adding a dimension of depth.

The radiographic reproduction is among the best available for temporal bone tomography. The anatomic macrosections are photographed in color, which is of great aid in differentiating adjacent structures in so small an anatomic area. Since the obverse side of the 2-mm macrosection represents the next 1-mm cut, the authors have used a photographic reversal process such that both sides of the specimen are oriented in the same direction. This simplifies correlating the specimen with the tomogram, the microradiograph,
