CONCLUSION
This study confirms that SSD/AHL CI recipients obtained significant
improvement of speech intelligibility in quiet and noise with a
follow-up of 5 years. The low percentage of non-users is an additional
strong argument to recommend cochlear implantation on the ear with a
profound hearing loss, especially in case of frail contralateral
acoustic-hearing ear, after trial of contralateral routing of signals
(CROS) devices.
