Background: Osteoclasts are bone-resorbing multinuclear polykaryons essential for bone remodeling, formed through cell fusion of mononuclear macrophage/monocyte lineage precursor cells upon stimulation by the RANK/RANKL system.Recent studies have revealed that a family of tetraspanin proteins, such as CD9, is critically involved in the cell fusion/

Summary: Cartilage framework exposure during total ear reconstruction requires an early salvage procedure and a secure coverage.We present a case that has been successfully covered by a retro-auricular fascia flap and a Kulturbeutel skin graft.Because we were dealing with a post-traumatic ear amputation with extensive scarring, the flap was designe
