目的:测量鼻部主要软骨的弹性模量数据,包括大翼软骨、侧鼻软骨和鼻中隔软骨,为运用有限元方法分析鼻畸形的形成提供数据基础。方法采集10例成人尸体鼻部软骨组织,包括大翼软骨、侧鼻软骨和鼻中隔软骨。分别测量鼻部软骨标本的压缩和拉伸状态下的应力-应变曲线,通过软件进行数据分析。结果对成人尸体鼻部各软骨的应力-应变曲线进行分析,通过最小二乘法拟合获得每个样本的弹性模量值。大翼软骨、侧鼻软骨和中隔软骨的压缩弹性模量统计值为(1.142±0.336) MPa、(5.84±1.246) MPa和(5±1.685) MPa;大翼软骨、侧鼻软骨和中隔软骨拉伸弹性模量统计值为(4.679±1.641) MPa、(8.601±2.131) MPa和(6.907±1.621) MPa。结论拉伸弹性模量普遍大于压缩弹性模量;侧鼻软骨弹性模量>中隔软骨弹性模量>大翼软骨弹性模量;相对于人体其他荷重软骨和骨性结构,鼻部主要软骨的弹性模量值较小。

Objective To measure the elastic modulus of nasal cartilage, such as alar cartilage, lateral nasal and septal cartilage, and to provide data base for the analysis of mechanical behavior of nasal deformity. Methods Ten cases of adult cadavers were collected. The tensile test and compression test were carried out in every sample by test machine. The experimental data was analyzed by statistic method. Results The every test data was fitted with a straight line, and the elastic module of every sample was the slope of the fitted line. The elastic modules were obtained by least square method. The compression and tensile modules of alar cartilage were (1.142±0.336) MPa and (4.679±1.641) MPa. The compression and tensile modules of lateral cartilage were (5.84±1.246) MPa and (8.601±2.131) MPa. The compression and tensile modules of septal cartilage were (3.85±1.685) MPa and (6.907±1.621) MPa. Conclusion Tensile modulus of nasal cartilage is generally larger than compression modulus; Elastic modulus of lateral nasal cartilage is larger than elastic modulus of septal cartilage, and elastic modulus of septal cartilage is larger than elastic modulus of alar cartilage; Comparing to the other load cartilage and bony structure in human body, the elastic module of nasal cartilages is lower.
