1Department of Mining and Materials Engineering, McGill University, Montreal, Quebec, Canada.
Summary
Understanding vocal fold mechanical properties is crucial for phonation. This review covers testing methods and models, offering insights for simulations and biomaterial design for vocal fold repair.
Area of Science:
- Biomechanics
- Biomaterials Science
- Acoustic Science
Background:
- Human vocal folds exhibit self-sustaining oscillations during phonation.
- The mechanical properties of vocal fold tissue are critical for phonatory function.
Purpose of the Study:
- To review mechanical testing methods and constitutive models for vocal fold tissue.
- To provide a multiscale perspective on vocal fold mechanical properties.
- To inform computational simulations of vocal fold vibrations and biomaterial design for vocal fold repair.
Main Methods:
- Review of existing literature on mechanical testing methods.
- Analysis of constitutive models for soft tissues.
- Discussion of multiscale characterization of tissue deformation.
Main Results:
- A wide range of elastic modulus values are reported in the literature.
- Discrepancies in reported values can be explained by a multiscale approach.
- Tissue deformation varies significantly with mechanical loading across different length scales.
Conclusions:
- A comprehensive understanding of vocal fold mechanical properties is essential.
- Multiscale analysis helps reconcile differing mechanical property measurements.
- This knowledge is vital for developing accurate vocal fold vibration models and effective biomaterials for vocal fold restoration.
