We wish to thank the following friends, colleagues, and mentors for their encouragement, support, and Guidance.

Dr. M. Eugene Tardy, Jr., has been an inspirational mentor and friend, whose advice and encouragement were instrumental in this project’s development.

Our mentors in Otolaryngology Head & Neck Surgery and in Facial Plastic & Reconstructive Surgery are a continuing source of inspiration and guidance.

Department Chairmen, Ed Applebaum at the University of Illinois at Chicago , and David Kennedy at the University of Pennsylvania , deserve special thanks for supporting and facilitating this undertaking.

Devin M. Cunning deserves much appreciation. His medical illustrations speak for them -selves, but do not tell of the countless hours of collaboration, hard work, and multiple re-visions.

Danette Knopp of Lippincott Williams & Wilkins provided publishing leadership from the very conception of the project to its completion.

Sara Lauber of Lippincott Williams & Wilkins played an instrumental role in guiding the manuscript through its final, critical stage.

Patrick Carr deserves thanks for his outstanding work as Production Editor.
