Authors' objectives:
To summarize the available information on the use of semi-implantable, middle ear hearing aids (The Direct System from SOUNDTEC Inc., Oklahoma City, US) to compensate for moderate to severe deafness due to disorders of the auditory nerve.
Authors' recommendations:
Semi-implantable hearing aids may be an option for those with moderate to severe hearing impairment who experience difficulties with conventional hearing aids. Limited available data suggest that the technology is effective and safe, though data on long-term outcomes in larger groups of patients are needed.
Health professionals require special training (provided by the manufacturer) to learn how to make the deep-canal impressions required for fitting the device.
A disadvantage with this technology is the need for a surgical procedure. Morbidity associated with this procedure has yet to be established, although results from the small studies to date are encouraging.
