The orbital cavity is still a "no man's land", as no surgical discipline has ever fully addressed it. This book will encompass the orbital cavity from a surgical perspective in a manner previously unseen. The described surgical details and presented results will show that impressive results can be achieved in very difficult and complex cases. Surgical procedures will be illustrated with drawings, sketches, and photographs (conditions before and after surgery, details of ongoing operations, etc.), and will be presented with a list of all possible complications. The intention is to provide the reader with both a monograph and surgical atlas of the orbital cavity. The following pages are a comprehensive systematic description of the complete surgery of the orbit. Surgical details, with both practical and theoretical viewpoints, are the author's contribution to the topic of surgical treatment of the orbit. At the end of each chapter, statistical data about Radmilo Roncevic's personal patients and results of their surgical treatments will be presented. This data will hopefully indicate the value of the doctor's surgical procedure and attitude toward the surgery and will help the readers understand better this surgical procedure.
