家兔鼻中隔黏膜瓣血供的实验研究

Blood supply of the pedicle nasal septum mucosa flap of rabbit in experiment

目的:研究家兔鼻中隔黏膜瓣的血供,为进一步制作鼻中隔带蒂黏膜瓣修复鼻腔及颅内缺损提供理论和实验依据。方法:以20只新鲜家兔尸体为实验对象,向其颈外动脉注射5ml纯蓝染色剂,沿家兔头部近正中纵行切开,观察鼻中隔黏膜瓣的血供。结果:家兔鼻中隔黏膜瓣的血供大部分来源于鼻中隔后下端的血管。结论:制作带蒂鼻中隔黏膜瓣时保留其后下端的血管可保证黏膜的血供,提高鼻中隔带蒂黏膜瓣的存活率。

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 ex- tremitas anterior part of nasal septum can guarantee the blood supply of mucous membrane,enhance the survival rate of nasal septum mucous membrane.
