9Foreword
The sentiment that Temporal Bone Imaging is a complex topic, is echoed by most radiologists—both neophytes and experts. The advances in surgical technique and the growing number of cochlear implant surgeries over the last decade mandate accurate delineation of the anatomy of temporal bone region. The advent of multidetector computed tomography (MDCT) has revolutionized the understanding of the pathology of this region but has also made the reporting of temporal bone pathology more complex. Using post-processing tools on MDCT, it is now possible to trace even minute structures in multiple planes. Temporal Bone Imaging is a dynamic field requiring constant effort on the part of managing clinicians to keep abreast with recent advances.
This book Temporal Bone Imaging is the first volume of a series titled Clinico Radiological Series and the authors have chosen a team of experts mostly from the All India Institute of Medical Sciences (AIIMS), New Delhi, India. They have attempted to simplify this rather complex topic and give a “management” context to the radiologists while reporting. The book also has invaluable contributions from head and neck surgeons, presented in lucid chapters.
There is detailed coverage of anatomy in a user-friendly, compact, point-wise text complemented by high-quality illustrations throughout the book. There is no compromise on detail and the book should prove useful to the surgeons as well. A unique feature is the formulation of structured reporting format for various disease groups which is enhanced by illustrative cases.
The topic and format of this book should make it a “trusted guide” for postgraduates and residents of radiology as well as otorhinolaryngology. It will be an asset to practicing radiologists and surgeons as well and reminds me of the adage ‘less is more’!

11Preface
‘What the mind does not know, the eyes do not see’; and head and neck radiology, especially temporal bone, essays the phrase better than any other radiology subspecialty. The head and neck anatomy is complex; and so is the radiology of head and neck diseases. The range of diseases involving the head and neck is wide and varies according to the anatomic regions involved. Among them, temporal bone probably harbors the most complex anatomic intricacies; and, hence, the most difficult area to interpret the abnormalities. Vital to hearing and equilibrium, temporal bone is the seat of various disease processes which are unique to it. A thorough knowledge of the regional anatomy and the normal variations is crucial in order to identify the imaging abnormalities, which can be quite subtle at times. And, even a trained eye may miss significant yet subtle findings unless a systematic approach is adopted for reporting.
Otorhinolaryngology and head and neck surgery is a rapidly expanding medical specialty which relies heavily on imaging. Practicing surgeons need to be aware of the basics of imaging involving their area of interest, as the same holds true for temporal bone surgeries. Similarly, radiologists practicing head and neck radiology need to be aware of the details of temporal bone anatomy and provide a structured and comprehensive report to the surgeon. Cochlear implant surgery is being performed quite frequently now and the radiologists need to be aware of the imaging requirements of the procedure. For the purpose, this book contains a separate dedicated section on cochlear implant imaging. This book is not intended to be a detailed text on temporal bone imaging, but we hope that it will help the busy radiologists and surgeons in interpreting images of the temporal bone. The structured reporting format and illustrative cases at the end of each section is aimed at this.
We welcome any feedback on enhancing the content of the book, which can be incorporated in the subsequent editions.
