Results With Cochlear Implantation in Adults With Speech Recognition Scores Exceeding Current Criteria

Abstract

The envelope of implantation candidacy criteria continues to expand as shown by this study's cohort. Patient satisfaction and speech recognition results are very encouraging in support of treating those who currently perform at a level above the conventional candidacy threshold but struggle with optimally fitted hearing aids.

Speech perception scores in cochlear implant recipients: An analysis of ceiling effects in the CUNY sentence test (Quiet) in post-lingually deafened cochlear implant recipients

“…Significantly fewer ceiling scores are reported and it found to be a more appropriate speech test to evaluate the current potential CI candidates compared to the previously used sentence tests (Gifford et al, 2008, Amoodi et al, 2012). …”

“…Firstly, when two different conditions, such as two speech coding strategies or two different programs are compared, reaching the ceiling scores leaves no room for such comparisons (Koch et al, 2004, Spahr and Dorman, 2005, Spahr and Dorman, 2004, Bassim et al, 2005, Amoodi et al, 2012. Secondly, when a recipient receives the highest possible score during the earlier assessments, identifying the further changes in their performance over time will become a problem.…”

“…Secondly, when a recipient receives the highest possible score during the earlier assessments, identifying the further changes in their performance over time will become a problem. A recipient's performance may continue to improve; however, the test is not sensitive enough to capture the subsequent improvements (Amoodi et al, 2012, Dowell et al, 2004, Lenarz et al, 2012, Gifford et al, 2008.…”

“…However, if postoperative scores cluster towards the maximum -as will be shown-the model loses its specificity. Hence, clinicians and researchers are urged to continuously examine the appropriateness of the speech test battery utilised, to determine changes in the recipients' performance (Gifford et al, 2010, Amoodi et al, 2012, Spahr et al, 2014.…”

Clinical Outcomes for Adult Cochlear Implant Recipients Experiencing Loss of Usable Acoustic Hearing in the Implanted Ear

“…Post-operative contribution of electric hearing provided by the Hybrid S12 device was reported to have more than compensated for any reduction in acoustic hearing thresholds. Gifford et al (2010) and Amoodi et al (2012) also examined outcomes for subjects with binaural speech perception scores that were outside the traditional candidacy guidelines in the United States and Canada. Gifford et al (2010) described post-operative improvement for a group of 22 subjects with preoperative binaural scores on the monosyllabic consonant-nucleus-consonant (CNC) word test in quiet that ranged from 30 to 60%.…”
