OBJECTIVE: To explore the blood supply of the pedicle nasal septum mucosa flap of rabbit, in order to supply the theory and experiment basis for making the pedicle nasal septum mucosa flap to repair nasal cavity and skull base defect. METHOD: Twenty rabbits corpses were induced into the experimental subject, and inject 5 ml blue ink into the external carotid artery, then longitudinal cut apart the middle head of rabbit, finally observe the blood supply of the pedicle nasal septum mucosa flap. RESULT: The blood supply of the pedicle nasal septum mucosa flap mostly come from the vessels of extremitas anterior part of nasal septum. CONCLUSION Keep the he vessels of extremitas anterior part of nasal septum can guarantee the blood supply of mucous membrane, enhance the survival rate of nasal septum mucous membrane.
