Long-term results using a piezoelectric semi-implantable middle ear hearing device: the Rion Device E-type.
The Rion Device E-type (RDE) has been applied to 39 patients with severe mixed deafness that could not be rehabilitated by surgical means or the conventional hearing aid. Careful follow-up studies have been conducted on all of them to assess clinical and audiologic results. The device could function more than 10 years, affording natural quality of hearing without howling and wearing discomforts. Functional principles of the device, indications, and surgical methods of implantation are described. The failures and delayed problems were also presented together with the preventive measures.
