Abstract

A study was performed to demonstrate that 24 h or postmortem changes at room temperature and one month of frozen storage at -20°C following quick freezing appear to introduce minimal changes on the viscoelastic shear properties of the canine vocal fold mucosa. On the other hand, frozen storage following a slow rate of cooling seemed to induce significant loss of tissue elasticity and viscosity.
