“…The onset of hearing loss was defined by patient history and objective diagnostics. If no correlation coefficient was presented but ample data was available, 23‐35 information on DoD and speech perception would be extracted, while patients with prelingual onset of deafness before the age of 5, 23,25,26,32 data of sequential implantations 28 and duplicate patient data 30,31 were excluded.

Objective Hearing loss is a highly disabling condition. Cochlear implantation is an established remedy if conventional hearing aids have failed to alleviate the level of disability. Unfortunately, cochlear implant (CI) performance varies dramatically. This study aims to examine the effects of duration of deafness (DoD) prior to cochlear implantation and the postoperative duration of implant experience with resulting hearing performance in postlingually deaf patients. Methods A systematic literature review and two meta‐analyses were conducted using the search terms cochlear implant AND duration deafness. Included studies evaluate the correlation between the DoD and auditory performance after cochlear implantation using monosyllabic and sentence tests. Correlation coefficients were determined using Pearson's correlation and Spearman rho. Results A total of 36 studies were identified and included data on cochlear implantations following postlingual deafness and postoperative speech testing of hearing outcomes for 1802 patients. The mean age ranged from 44 to 68 years with a DoD of 0.1 to 77 years. Cochlear implant use varied from 3 months to 14 years of age. Speech perception, which was assessed by sentence and monosyllabic word perception, was negatively correlated with DoD. Subgroup analyses revealed worse outcomes for longer DoD and shorter postoperative follow‐up. Conclusion DoD is one of the most important factors to predict speech perception after cochlear implantation in postlingually deaf patients. The meta‐analyses revealed a negative correlation between length of auditory deprivation and postoperative sentence and monosyllabic speech perception. Longer DoD seems to lead to worse CI performance, whereas more experience with CI mitigates the effect.

“…Outcome measures have usually focused on performance in conventional audiological measures of speech perception (Blamey et al, 1992;Gantz et al, 1993;Fraysse et al, 1998;Bredberg et al, 2003; for theoretical background see Blamey et al, 1996). However, the benefit provided by enhanced enjoyment of everyday activities has also been recognized as more tangible from the patient's perspective.…”

“…It could injure several areas of the cochlea, including outer hair cells (OHC) in the organ of Corti, in the spiral ganglion and in the stria vascularis. The human cochlea contains 5,000 inner hair cells (IHCs) and 15,000 OHCs (Bredberg et al, 2003). One of the most common causes of hearing deficits is the loss of sensory HC that is due to a variety of factors like as an excessive exposure to noise (Cassandro et al, 2003).…”

Many hearing disorders are associated with the damage or loss of sensory hair cells (HC) which can produce a profound and irreversible deafness. Apoptosis pathway is reported to play an important role leading to rapid expansion of the HC lesion after exposure to intense noise. Furthermore, progress made over the last year in understanding molecular mechanisms involved in the proliferative and regenerative capacity of sensory cells in the mammalian inner ear has raised the possibility that targeted therapies might prevent the loss of these cells and preserve the patient's hearing. A first step towards the successful therapeutic exploitation is a better understanding of the different pathways that control survival and proliferation of sensory cells. In this review, we provide an overview of recent findings concerning the possibility to prevent apoptosis in auditory cells. We also show the current knowledge on the molecular mechanisms involved in the potential regenerative behavior of these cells and the progress of gene therapy to prevent deafness noise-induced.
