Due to the complex anatomical structure of the temporal bone, imaging diagnosis requires a very high degree of expertise. This atlas is not only helpful to assess pediatric ear disorders accurately, but also provides a treasure trove to experts. It consists of a pediatric temporal bone imaging atlas followed by case reports of typical pediatric ear diseases. In the first part complete contiguous temporal bone CT sections of an infant and an older child are shown along with a detailed listing of anatomical names of the structures. It further presents developmental changes in size, shape, location and orientation of the primary components of the temporal bone. The second part contains case images in combination with reference illustrations of a healthy child in the same age range allowing the reader to identify the key findings of the disorder with only one reference book at hand. Further images illustrate the posttreatment follow-up. This publication which is translated from the successful Japanese edition (2011) will be essential for otorhinolaryngologists and pediatricians particularly interested in pediatric ear diseases. Its unique layout makes it also a very effective tool for students learning image diagnosis.
The foundation for temporal bone imaging diagnosis lies in obtaining a thorough understanding of the earâs normal anatomical structures and their three-dimensional relationship. Through repeated comparison and identification of the details of normal structures and the anatomical terms that describe them, one gradually forms a mental image of the temporal boneâs overall three-dimensional orientation. When one concurrently views clinical case images, oneâs eyes are drawn naturally to those forms that differ from the norm, which can then be compared to various known disease findings to arrive at an accurate diagnosis. This process also applies to pediatric cases but, with the exception of minor ailments such as otitis media, encounters with infant diseases in everyday clinical practice are infrequent, and examples of imaging diagnosis even rarer. Consequently, pediatric images are usually interpreted with normal adult anatomy in mind. However, the temporal bone of infants in particular differs from that of an adultâs with respect to the sizes and relative ratios of each component, so caution is required in reading and interpreting findings.
This chapter displays a complete series of serial cross-section and descriptive images, without omission, of temporal bone CT axial sections and coronal sections from both infants and older children. By examining the images from infants and older children, first separately and then in comparison,...
