use of frozen autogenous bone flap for cranioplasty

ABSTRACT

The artificial methods of cranioplasty such as using metals or alloplastic materials have some disadvantages, comparning with autogenic bone flaps. We tried to show that the autogenic flaps have less complications when used in cranioplasty. With good sealing of bone flap after extraction and preserving in -70 to -800 C, in Immounology Department, the autogenic bone was fixed in the previous site. From 10 patients, one of them developed infection and osteomyelitic bone was extracted. No bone resorption was detected. Comparing with other studies of autogenous bone flap cranioplasty, we have similar rate of complication. In other studies, the rate of infection was almost equal to our results. So using autogenous bone in our center is advisable
