Young Age Is a Positive Prognostic Factor for Residual Hearing Preservation in Conventional Cochlear Implantation

Abstract

The preservation of residual hearing after conventional CI is possible. Young age seems to have a positive impact on hearing preservation.

Hearing Preservation After Cochlear Implantation May Improve Long-term Word Perception in the Electric-only Condition

“…Although hearing preservation rates reported in the literature vary greatly, this rate is comparable to other reports that investigated hearing preservation rates with full-length CI electrodes (15)(16)(17).…”

“…The assessment of residual acoustic hearing close to the maximum output of the audiometer leads to a ceiling effect causing an underestimation of the postoperative hearing loss and an overestimation of hearing preservation rates. To take this effect into account, different hearing preservation classifications have been proposed (7)(8)(9)(10)15). The advantage of the HEARRING group hearing preservation classification system (11) is that the postoperative PTA is related to the preoperative PTA.…”

Impact of Perioperative Oral Steroid Use on Low-frequency Hearing Preservation After Cochlear Implantation

“…Among the nonsurgical variables that may be influential, advanced patient age has been previously associated with a lesser degree of success (1,22,23). The explanation for this phenomenon has not been clarified, although Cosetti et al hypothesize that the same elements responsible for physiologic agerelated hearing loss could account for this trend.…”

Effects of Round Window Opening Size and Moisturized Electrodes on Intracochlear Pressure Related to the Insertion of a Cochlear Implant Electrode

“…It was described to be open in about one third of temporal bones [Gopen et al, 1997], and this patency is discussed to be age-dependent [Wlodyka, 1978]. In turn, this variation might have clinical consequences, such as the higher rate of hearing preservation in younger patients [Anagiotos et al, 2015], leaving the cochlear aqueduct not ideally as a pressure equilibrator for the whole patient population. Therefore, the size of the round window opening seems to be crucial for intracochlear pressure gradients during the array insertion.…”
