Demineralized bone-fibrin sandwich for genioplasty

Osseous genioplasty is a versatile technique to improve chin and facial aesthetics. It carries several benefits compared to an alloplastic implant, but the downsides of an intersegmental gap and lateral stepoffs must be weighed. These areas are typically left open, despite being subject to unpredictable resorption or incomplete osseous healing. We describe the strategy of using a combination of demineralized bone matrix (DBM) and fibrin glue to promote bone fill while smoothing contours and transitions along the genioplasty. Our retrospective study included 32 patients who underwent genioplasty with the DBM-fibrin sandwich. There were no genioplasty-related complications at the 6 months follow-up. Our results indicate that this technique is safe and is a valuable addition to possible graft material for genioplasty.
