B. Svensson and colleagues continued to work on restoring vocal fold function after injury in an animal study.
Like Sayers, he has tried to restore a vocal music to Dante - by inserting archaisms from 18th-century Irish ballads.
This procedure failed to restore satisfactory vocal function in 4 cases.
This low-amplitude and weak neural excitation, compared with the large spikes and bursts in RLN motorneurones, can restore the reinnervated vocal fold bulk, tone and tension, rather than the functional motion [24].
The two are collaborating with a team of physicians and researchers led by Dr. Steven Zeitels of Massachusetts Eye and Ear Infirmary that is studying ways to restore elasticity to damaged vocal cords.

This study aims to provide a better understanding of mechanical properties that can be used to build computational simulations of vocal fold vibrations and pave the way for the design of biomaterials to restore biomechanical properties in damaged vocal folds.
Zeitels was already starting to develop a new type of material that could be implanted into scarred vocal cords to restore their normal function.
Postoperative perceptual evaluation, acoustic analysis and MPT showed that our procedure could provide normal or near-normal phonatory function, because it can restore physical properties of the vocal fold necessary for normal phonatory quality.
Also, tests showed that PEG30 can restore vibration to stiff, non-vibrating vocal folds such as those seen in human patients suffering from vocal-fold scarring.
