Low Pediatric Cochlear Implant Failure Rate<subtitle>Contributing Factors in Large-Volume Practice</subtitle>

Abstract

A very low rate of failure occurs in children who receive CI devices, and several factors may account for this low rate. Children who develop meningitis before CI appear to be at an increased risk of device failure.

Rates of revision and device failure in cochlear implant surgery: A 30‐year experience

“…The analysis of the current study has revealed subsequent generations of implants requiring less revision surgery, which is consistent with progressive improvements in device design and manufacture. This is common to all device manufacturers including Cochlear, MedEl, and Advanced Bionics . Our analysis was not greatly influenced by the Nucleus CI500 series recall initiated in September 2011, as our data collection was completed 3 months prior in June 2011.…”

Cochlear Implant Failure and Revision Surgery in Pediatric Population

“…Rates in the literature ranged from 2.9% to 12.9% in children [3][4][5][6][7][8] ( Table 2). Rates in the literature ranged from 2.9% to 12.9% in children [3][4][5][6][7][8] ( Table 2).…”

“…4,8,10,[12][13][14] The poorer performances were secondary to either partial insertion or neurological abnormality. These data are consistent with those of the literature.…”

European Bilateral Pediatric Cochlear Implant Forum Consensus Statement

“…Over the lifetime of these children, many will require revision surgery for device failure, infection, and perhaps to take advantage of improvements in technology. Although the great majority of reimplanted CI individuals are observed to regain their previous hearing performance with some even showing additional improvements (most likely attributed to advances in implant design and speech algorithm technology), some reimplanted cases do not (47,48). This is a significant consideration for the future.…”
