    Abstract:
    Mandibular condyles are reconstructed immediately with costochondral grafts (CCGs) in children for several temporomandibular conditions, including ankylosis, benign neoplasia, and chronic arthritis. A prerequisite for growth of CCGs is that they are properly revascularised, but the revascularisation process has not to our knowledge so far been examined. The aim of the present study was therefore to investigate the revascularisation of CCGs when they were used for immediate reconstruction of the mandibular condyle in juvenile domestic pigs. Eleven mandibular condyles were experimentally resected and immediately reconstructed with CCGs. Microangiograms with an Indian ink solution were done 2, 4, 8, and 12 weeks after the reconstructions. The density of vessels was higher in measurement zones facing soft tissues than in those facing mandibular bone at all time points. Revascularisation of the growth plate originated from the surrounding recipient soft tissues and not from an endosteal blood supply from the host mandible ramus.
