When cancellous bone can be used, e.g., for bridging gaps in orthognathic surgery (patients 2, 6, 8, and 9), trauma (patients 3 and 5), or post-traumatic and oncologic recon­ structive surgery (patients 1, 4, and 7), tibial grafts may be very suitable (Table 1). Particulate cancellous bone grafts do not have the mechanical strength desired for reconstruction of large defects without additional support. On the other hand, because of the large open areas in these grafts, (re)vasculari­ zation usually takes place rapidly, thereby bringing cellular regeneration, remodeling, and gradual substitution with new bone formation where old bone has disappeared2,3,10,11,13. The complication rates of tibial graft harvesting are reported to range from 1.3% to 3.8%, which compares favorably with the complication rate of iliac crest harvesting of 8.6-9.2%7,9. The nine patients of this series do not allow us to give a meaningful complication rate, although a complication rate of 0% is encouraging. The fact that the bone grafts tend to be oily did not cause any morbidity in the early follow-up period. Because of possible growth-center interference, the use of the tibia as do­ nor site is contraindicated in children and adolescents. In questionable situa­ tions (e.g., an 18-year-old man), pre­ operative radiographs should be made to verify closure of the epiphysial plates and cessation of growth. This modified graft harvesting tech­ nique is simple, is not time-consuming, and produces reasonable amounts of cancellous bone with a simple, handdriven instrument. Other techniques need drilling equipment, tourniquets, and osteotomes4,9,15, and may cause weight-bearing limitations. This modification allows weight bearing immediately postoperatively, needs neither a bloodless field nor drainage, and does not appear to cause complications or morbidity. The tibial plateau can be considered a suitable do­ nor site for defined indications in bonegrafting procedures in oral and craniomaxillofacial surgery. A cknow ledgm ents. We thank Dr A. C.
