A modified technique of harvesting tibial cancellous bone and its use for sinus grafting

Autogenous bone is the gold standard graft for sinus augmentation. The harv est of autogenous bone grafts from intraoral sites does often not provide s ufficient bone volume and quality. A modified technique of harvesting a tib ial cancellous graft is presented, With a micro-bone saw, a bony lid is pre pared at the medial condyle of the tibia. The lid stays attached to the ten dinous pes anserinus. Following the harvest, the lid is repositioned accura tely. This method offers some distinct advantages. A sufficient amount of b iologically highly valuable cancellous bone may be harvested for sinus graf ting and possibly other surgeries with bone augmentation. The procedure may be performed under local anaesthesia and does not require hospitalisation. Neither major complications nor serious postoperative morbidity were obser ved.
