Hearing and Quality-of-Life Outcomes After Cochlear Implantation in Adult Hearing Aid Users 65 Years or Older

Abstract

for the CI532 Study Group IMPORTANCE Hearing loss, especially moderate to severe forms, has the potential to negatively affect an individual's physical, social, emotional, and cognitive well-being. Moreover, having ineffective binaural hearing increases difficulty understanding speech in noise and leads to a greater degree of social isolation and loneliness and a reduced quality of life (QoL).OBJECTIVE To explore the audiometric and holistic effects of cochlear implantation in a group of adults 65 years or older compared with an optimized bilateral hearing aid condition. DESIGN, SETTING, AND PARTICIPANTSThis ad hoc secondary analysis of a prospective, single-subject, repeated-measures nonrandomized clinical trial included 13 cochlear implantation centers across the United States. Participants 65 years or older with postlingual bilateral moderate-to-profound sensorineural hearing loss with aided Consonant-Vowel Nucleus-Consonant (CNC) word scores in quiet of 40% or less in the ear to undergo implantation and 50% or less in the contralateral ear were included in the analysis. Baseline QoL testing was performed after 1 month of optimized bilateral hearing aid use.

Speech Recognition as a Function of Age and Listening Experience in Adult Cochlear Implant Users

“…Cochlear implantation is an effective treatment option across the lifespan for patients with moderate‐to‐profound sensorineural hearing loss (SNHL) and limited speech recognition with appropriately fit hearing aids 1–11 . Cochlear implant (CI) recipients demonstrate significant improvements in speech recognition within the initial months of device use, 9,12 though a wide variability in performance is observed 13–16 .…”

“…Cochlear implantation is an effective treatment option across the lifespan for patients with moderate-toprofound sensorineural hearing loss (SNHL) and limited speech recognition with appropriately fit hearing aids. [1][2][3][4][5][6][7][8][9][10][11] Cochlear implant (CI) recipients demonstrate significant improvements in speech recognition within the initial months of device use, 9,12 though a wide variability in performance is observed. [13][14][15][16] Factors observed to influence the variability in speech recognition within the initial months of CI use include preoperative acoustic hearing, 17 duration of severe-to-profound SNHL, 12,13,[15][16][17][18][19][20] and age at implantation.…”

Neural activity of the auditory cortex predicts speech recognition of patients with asymmetric hearing loss after cochlear implantation

“…These patients, with a pre-operative AI-PAC ≥ 4.2%, showed better monosyllabic word recognition than those with a lower AI-PAC. Nevertheless, monosyllabic word recognition was poorer than expected for 6-months follow-up examination in both groups 31 – 33 .…”

A New Pathogenic Variant in POU3F4 Causing Deafness Due to an Incomplete Partition of the Cochlea Paved the Way for Innovative Surgery

“…It is thought that it can directly affect the health of the person while participating more fully in daily life activities. In a multicentric study, it has been shown that the CI applied to adults over the age of 65 significantly benefits hearing and quality of life and can facilitate the concept of healthy aging [ 69 ]. Consequently, CI surgery was thought to be the most effective solution for our patients.…”
