摘要/Abstract

摘要： 目的探讨切取悬吊拉伸法在犬喉中段声带固有张力测量中的应用效果。方法切取游离的犬喉中段声带(包括完整的声带5层结构),用悬吊拉伸的方法将声带样本拉升至原有长度,通过拉伸所需要的砝码质量测量其固有张力。测量喉腔样本的主要几何参数,评估样本的可靠性。结果将声带样本悬吊拉伸至固有10 mm长度所需要的砝码质量均数为22.06 g。所需砝码质量与实验动物的体质量及体型大小无相关关系(P=0.985)。实验测量的主要几何参数与文献报道较为一致。结论切取悬吊拉伸可较为精确测量出犬喉中段声带的固有张力。

Abstract: Objective To measure the intrinsic tension of central part canine vocal fold. Methods Weights suspension method was employed to stretch the excised canine vocal fold(including the entire five-story structure)to its' original length, using the weights mass to evaluate the intrinsic vocal fold tension. Major geometrical parameter of the canine vocal folds were measured and compare to those reported by literatures to assess the reliability of the samples. Results The average weights mass used to stretch the suspended vocal fold sample was 22.06 g. Vocal fold tension was showed to have no correlational relationship with the weight of experimental canines. Major geometricalparameterof these canine vocal folds correspond with those reported by literatures. Conclusion The intrinsic tension of middle part canine vocal fold which is necessary in establishing vocal fold finite element model can be measured by weights suspension method.
