[Histological and electrophysiological study of cryosurgery of the cochlea of guinea pigs].

For studies on cochlear function after inner ear trauma, cryosurgery gives reproductive morphological changes that may help the understanding and the correlation of hair cell loss with cochlear physiology. In all cases of partial destruction of the organ of Corti we noticed a completely reversible limitation of hearing, whereas when injuring the organ of Corti in the whole cochlea a restriction of function persisted. We could never induce complete deafness.
