Analysis of curves Na-24 efflux from membrane labyrinth containing stria vascularis.

abstract：CONCLUSION:A man-made bone tunnel of 1.5 turns around the modiolus can be created in cases of total cochlear ossification. Patients with ossified cochlea types I and II achieved satisfactory hearing results after cochlear implantation (CI). Patients with ossified cochlea type III, in which the modiolus is damaged by th...
