Abstract
The current reviews support the notion that cochlear implants have been highly successful for those with severe to profound hearing losses and tend to result in improved HRQOL. At the same time, adults, children, and elderly adults who received cochlear implants demonstrate wide variability in their outcomes; they have to participate in rehabilitation, and might face challenges in their daily lives as related to their hearing loss. It is important to remain objective and realistic when providing information to potential recipients and their families. Despite significant research, outcomes are varied and still there is no reliable and accurate pre-surgical predictor of post-surgical performance in cochlear implant recipients that would allow clinicians to confidently predict how prospective candidates how will do with the implant (Zeng, 2004). It is important to incorporate an evaluation or framework of quality of life in cochlear implant rehabilitation centers, as quality of life is a multi-faceted construct that provides rich information about the recipients’ personal experiences in their in daily life across various domains of functioning. As such, information about quality of life can provide useful information to professionals in order to support children and adults who undergo cochlear implantation and their families.
Speech understanding in noise is improved with bilateral cochlear implantation with unambiguous evidence that the second implant expands the sound field for effective speech recognition.. The correlation of the subjective and objective results confirms the practical benefits in daily activities. Although there was improvement with a second Cochlear implant even after a long implantation interval, short intervals lead to better results.
Most commonly, it has been found that cochlear implants improve the HRQOL among both prelingually and postlingually deafened adult recipients. Based on cochlear implant user subjective reports, it seems that cochlear implants provide better sound perception; facilitate greater communication abilities; and improve psychological aspects including increased safety, increased social participation, confidence, independence, and better opportunities in the work place. However, it should be noted that there is much variability between individuals, and the impact of cochlear implants on the daily lives of adult recipients is yet to be fully explored.
