Novel pre-surgical screening for cochlear implant candidates

Joseph Manuel Santos Rodriguez, Purdue University

Abstract

Individuals with normal vision but who suffer from profound hearing loss can benefit from cochlear implants in spoken language comprehension over lip-reading. This benefit can vary significantly across implantees. It is desirable to develop a behavioral test battery that may be used in a pre-surgical setting to identify good/poor implant candidates. Such a test should use only visual or self-reported measures. An existing test is visual-only word identification using lip-reading, but this has not yet been found to be a strong indicator of post-implant benefit. It is hypothesized that cognitive function, particularly executive function, may play a role in this benefit. This study evaluated three mechanisms of assessment to identify the best test battery for word identification performance. Preliminary results suggest that two of visual-only forward/backward discrimination, visual-only word identification, and self-reported executive function testing are sufficient to identify good/poor implant candidates.
