Restoring hearing in deaf ear |
"Results of the present study showed that adults with acquired moderate-to-profound UHL benefit from receiving a CI, with improved ability to localize sound on the horizontal plane and modest benefits for masked sentence recognition in a subset of conditions."
(Buss et al. 2018)
"A CI is the only device that can restore auditory input in the deafened ear and provide the user with access to the binaural hearing system." (Kurz et al. 2020)

Binaural hearing |
"Patients with a postlingual onset of a profound hearing loss in one ear and normal hearing or only a moderate loss in the other ear are able to make the effective use of a CI in the profound-loss ear in conjunction with acoustic stimulation of the other ear."
(Lorens et al. 2019)

Decreased head shadow
(in next point) |
"CIs provide listeners with unilateral deafness important benefits for speech perception in complex spatial environments, including a larger head-shadow benefit when speech and noise originate on opposite sides of the head." (Bernstein et al. 2017)

Improved SNR - significant reduction of
head shadow, slight improvement in summation & squelch |
"To understand the impact of SSD, it is imperative to review the importance of binaural advantages such as the head shadow effect, localization, binaural summation, and the binaural squelch effect. The loss of these advantages due to SSD may be detrimental in many listening situations" (McKay 2010)
Tavora-Vieira et al. (2013) observed significant improvement in speech in noise scores for 3 challenging spatial configurations (indirect citation / Tavora-Vieira et al. 2013)

Better localization and directionality |
Literature shows a statistically significant improvement of localisation abilities after CI implantation, but the duration of deafness influences the results (consensus statement)

Increased confidence in
social situations |
"When analyzing the SSQ results with a one-way repeated measures ANOVA, it is shown that, in daily living, the CI adds significantly to the acoustic hearing in both groups when it comes to speech understanding and quality of sound." (Vermeire et al. 2009)

Increased listening and language
acquistion |
McKay (2010) states, that getting access to the advantages of binaural hearing, leads to increased listening and language acquistion. (indirect citation / McKay 2010)

Increased scholastic performance |
During the period of development, binaural hearing is even more important in young children than it is in adulthood. As shown in longitudinal studies, pediatric UHL can lead to significant psychosocial difficulties and school problems (…) (indirect citation / Lieu et al. 2012)

Increased quality of life and opportunities for individual recipients |
"Furthermore, cochlear implantation in patients with SSD and additional tinnitus was successful for tinnitus reduction and able to improve quality of life."

Increased music appreciation |
"Music enjoyment from electric stimulation is extremely poor relative to a readily interpretable NH baseline for CI-SSD listeners. However, the combination of this unenjoyable signal presented through a CI and an unmodified acoustic signal presented to a NH (or near-NH) contralateral ear results in enhanced music enjoyment with respect to the acoustic signal alone." (Landsberger et al. 2019)
"For all objective tests of music discrimination and speech perception in noise, there were no statistically significant differences between MED-EL and Cochlear CI systems. Subjectively, four subjects thought their MED-EL device was better than their Cochlear device for music appreciation. Four thought that music sounded more natural, less tinny and more reverberant with their MED-EL CI than with their Cochlear CI." (Harris et al. 2011)

MRI conditionality |
"Patients undergoing 1.5 T MRIs with devices including a diametrically bipolar magnet or a rigid implant screw fixation, experienced no pain, even without headbands." (Todt et al. 2018)
"Intraindividual artifact size differences between the three magnets and are smaller than interindividual maximum artifact size differences. 3 T MRI scans, in comparison to 1.5 T MRI scans, show a difference between soft artifact areas. Conclusion: We observed no major difference between maximum implant magnet artifact sizes of the three implant magnet types." (Todt et al. 2020)
