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.

Key words: Vocal fold tension, Canine, Larynx
