AIM To observe the possibility and developing regularity of axial cartilage-cutaneous flaps formed by simultaneous implantation of vascular bundle and free perichondrium PC into random pattern flap and discuss new approaches of obtaining cartilage-cutaneous flaps and appropriate time to elevate revascularized cartilage-cutaneous flaps. METHODS The experiment was conducted in the Experimental Animal Center of Shanghai Sixth People's Hostpital Shanghai Jiaotong University from May to November 2005.①Totally 32 healthy New Zealand rabbits received design of 6 cm×2 cm random flaps on trachelo-back and simultaneous implantation of central arterial and venous bundles of left ear as well as free PC chaffs of right ear into flaps which formed in different time island-like PC flaps taking vascular bundle as pedicle. Progress of revascularization was observed PC inside the cartilage-cutaneous flaps were taken out in different time the formation of cartilage was observed. ②Experimental animals were randomly divided into 8 groups 1 3 4 6 weeks of post-operation group 3 4 6 8 weeks after formation of PC into cartilage group with 4 animals in each group. ③Subjects of 4 groups of which vascularization were observed were made into island-like cartilage-cutaneous flaps taking vascular bundle as pedicle and then done with fluorography photographs were taken 5 days after that to record the survival rate of flaps 2 samples of each group received ink-perfusion respectively for histological inspection and transparent specimen making PC of animals in 4 groups with formation of PC observed were taken out and inspected of their newly bornt PC specimens with histological inspection in corresponding time. RESULTS Totally 32 rabbits entered final analysis. ①Status of vascularization Fluorography rates and survival rates of prefabricated cartilage-cutaneous flaps were 16.2%/15.2%,65.9%/41.9%,100%/88%,100%/91.1% respectively Tissue sections of ink-perfusion indicated that new-born vessles increased with pefabricating time increasing. There were lots of micrangium and ink granules around vascular bundles and in subcutaneous tissues 4 6 weeks after operation ink granules distributed in the vessels of PC And there are similar results in transparent specimens.②Formation of PC into cartilage Inspection of PC tissue sections in 3 4 6 8 weeks groups after operation indicated that abilities of PC proliferation and differentiation were consummated with the prefabricating time increasing and there were cartilage osteoblasts classic form in 68 weeks after operation groups some had differentiated towards carlage cells and there were cartilage capsules formed. There were great amount of cartilage matrix formed with alcian blue staining. Compared with 4 weeks after operation group there were remarkable significance in differences P < 0.05. CONCLUSION ①Cartilage-cutaneous flap can be transformed into axial cartilage-cutaneous flaps by implanting of vascular bundles and PC which provide new methods and experimental basis for clinical obtaining of cartilage-cutaneous flaps with transferable vascular pedicles.②6-week after implantation of vascular bundles and free PC into random cutaneous flaps capabilities of PC proliferation and differentiation into cartilage as well as vascularization gradually become better at which time prefabricated cartilage-cutaneous flap can be elevated safely.
