Abstract
The calvarium has become an increasingly popular bone-graft donor site. Previously described harvesting techniques are often difficult to perform and may produce unsatisfactory bone fragments. However, full-thickness bone grafts taken from the region of the temporal fossa, beneath the temporaiis muscle, have proven to be of high quality and technically easy to obtain. In our experience with eight patients, temporal fossa bone grafts were used primarily around the orbit, including reconstruction of the orbital floor, frontal bone, and zygoma. The procedure begins with a hemicoronal or bicoronal incision; the temporalis muscle is reflected, and an underlying bone plate up to 4 X 6 cm is removed. The resulting bone graft is consistently 3 to 4 mm in thickness. The cranial defect is packed with bone debris, and the muscle is replaced. This technique has proven to be safe, technically simple, consistently productive of high-quality bone grafts, and within discernible donor-site deformity.
