Autogenous bone grafts and bone substitutes--tools and techniques: I. A 20,000-case experience in maxillofacial and craniofacial surgery

Alloplastic bone substitutes can be used to alter facial contour. In contrast, autogenous bone grafts have a successful 80-year history of restoring facial contour as well as the basic functional support of the craniofacial skeleton. The traditional procedures for harvesting and using autogenous bone grafts are not obsolete. During the past 30 years, the techniques have been refined and new sources have been found, such as calvarial grafts. New tools were required and have been designed to make harvesting of grafts easier and faster for the surgeon and safer and less expensive for the patient. Four short articles under the heading of "Techniques and Tools" are presented addressing the harvesting of (1) iliac, (2) costal, (3) tibial, and (4) calvarial grafts. These articles are based on the experience of six surgeons using the same technique and instruments in more than 20,000 autogenous bone grafting procedures. (These figures represent the group experience as of 2001. Since then, one of the junior coauthors has retired, but the remaining five continue to harvest autogenous bone grafts on a regular basis. So, the group experience as of 2004 is in the range of 23,000 procedures). The-senior surgeon's experience of 9500 procedures spans a period of 50 years (from 1946 to 1996). For the other surgeons (10,500 procedures combined), the collection period was 25 years (from 1975 to 2000).
