This book is the result of more than 10 years of inquiry. It began when the senior author (Robert Thayer Sataloff) was a resident in the Department of Otolaryngology–Head and Neck Surgery at the University of Michigan, USA. The teaching at that time suggested that the location of the facial nerve in congenitally malformed ears was unknown. This produced uncertainty and fear in the otologic surgeon. In fact, many otolaryngologists were opposed to corrective surgery for hearing improvement, especially in patients with unilateral malformations, believing that the risk of facial paralysis was greater than the potential gain. It seemed to the author that if one understood the embryology of the facial nerve, it would be possible to make a reasonably accurate prediction of facial nerve position in most cases. However, when the authors went to the library to look up facial nerve embryology and correlate it with embryology of the ear, the literature review was almost more challenging than the surgery itself.

The authors are indebted again to Mary J Hawkshaw, BSN, RN, CORLN for her invaluable help in writing this book, to Debbie Keeler for preparation of the manuscript, and to everyone acknowledged in the first edition.10

I am deeply indebted to many people for assistance in the preparation of this book. First, my deepest appreciation goes to my father, Joseph Sataloff, who inspired me to enter otolaryngology and advised me to train at the University of Michigan, and who has continued to share his wisdom with me throughout our years in practice together. The academic and clinical training I received from Walter P Work, Charles J Krause, Malcolm D Graham, and others in Ann Arbor has been invaluable; as was my exposure in Los Angeles with Bill and Howard House and their associates. I am indebted to all of my mentors for helping prepare me to write this text. This work was also aided immeasurably by Merle Lawrence, PhD, who was kind enough to permit me to study his collection of embryology slides. I am also indebted to Kyle Rarey, PhD, for making Dr Lawrence's slide collection available to me again recently, for reassessment and for his invaluable assistance in reviewing histologic materials. It is impossible to thank adequately my friend and colleague Zaven Jabourian, MD. During his first and second years in practice as an otolaryngologist, he generously donated his time, talent and friendship to render the illustrations in this book. They are superb, and the fact that they were drawn by an otolaryngologist made the process immeasurably easier. A very special debt of gratitude goes to Mary Hawkshaw, RN, BSN, my nurse, editorial assistant, and patient friend, who devoted almost as many hours to this manuscript and its photographs as I did. Without her dedicated and expert assistance, preparation of this book probably would have taken another year or two. I also express my gratitude to Helen Caputo, who retyped the manuscript more times than either of us can count, and to Kathy Mayer for her assistance in labeling the illustrations. Finally, I express deep appreciation to my understanding and tolerant wife, Dahlia Sataloff, MD, who put up with innumerable ruined evenings, weekends, vacations, and summer trips while I was engrossed in completing this project.
