Claim:
1. A method of treating a subject having a phonatory mucosa with diminished functional vibratory capacity and diminished phonation, the method comprising locating a phonatory mucosa with diminished functional vibratory capacity in the subject; and injecting into the phonatory mucosa a hydrogel material that comprises an elastic shear modulus ranging from about 15 to about 121 Pa measured at a frequency of 10 Hz in an amount effective to increase functional vibratory capacity of the phonatory mucosa and improve phonation; wherein the hydrogel material comprises a first cross-linked polymer and a second polymer, and wherein the hydrogel material comprises an interpenetrating or semi-interpenetrating network of the first and second polymers.
