摘要
目的研究耳支架覆盖组织瓣的模板设计,探讨一种精确可靠的组织瓣设计方法。方法运用工程图学理论和CT三维测量技术,对40只发育正常耳廓的表面三维形态进行近似平面展开,据此展开图形设计耳支架覆盖组织瓣模板。结果健康人耳廓表面三维形态的展开图形具有大致相似的基本形状,据此基本图形的关键点可绘制出SMAS组织瓣的简化模板。结论应用CT三维测量模板设计耳支架覆盖组织瓣准确可靠。
Objective To study the template design of tissue flaps for covering auricular cage in order to acquire accurate and reliable design method. Methods By the theory of engineering drawing and three- dimensional measuring on CT image, three dimensional configuration of 40 auricular surfaces were expanded approximately, and the character of them was analysed for the template design. Results It is similar of the expanded graphs of auricular surface three dimensional configuration in healthy persons, and simplified template of tissue flaps is drawn based on the key points of the above graph. Conclusions CT three-dimensional measurement of auricular surface configuration can be used to design the template of tissue flaps for covering auricular cage, and can provide accurate and reliable template of tissue flaps for clinics.
