he desire to teach and the fulfillment attained from teaching T have again prompted us to produce a work that we hope will be both useful and enlightening to our readers. The field of oculoplastic surgery has grown and evolved to include all aspects of eyelid and facial plastic surgery. Our literature must now reflect the advancements and direction of our field. Knowledge of anatomy, the basis of all surgery and the root of surgical princi pIes and techniques, is the basis of our ability to deli ver the highest quality care to our patients. We have therefore combined text and diagrams, and supplemented them with CD-ROM digital video technology to provide to those who wish to perform this surgery the best possible instruction and prepa ration. We hope that our attempts to accomplish this will be rewarded by the use of our material by our colleagues and the acknowledgment of our unique and logical progression in the field of eyelid and facial plastic surgery. Future volumes in this series will cover other aspects of eyelid, lacrimal, facial, and orbital surgery.
