The Chronological Evolution of Cochlear Implant Contraindications: A Comprehensive Review

Nezar Hamed et al. J Clin Med. .

Abstract

Cochlear implantation has emerged as a transformative intervention in addressing profound hearing loss, offering a paradigm shift in auditory rehabilitation for individuals with restricted auditory function. Throughout its history, the understanding of contraindications for cochlear implant (CI) surgery has evolved significantly. This review comprehensively analyzes the chronological advancements in the understanding of CI contraindications, examining studies conducted from historical timelines to the present. Recent research has revealed significant developments in the field, prompting a reevaluation of established criteria and resulting in expanded indications for CI. The chronological evolution of contraindications underscores the transformative nature of the field, offering potential improvements in outcomes and enhancing the quality of life for individuals with profound hearing loss. In conclusion, this narrative review emphasizes the dynamic nature of the field, where the reevaluation of contraindications has created new opportunities and broader indications for CI. The emerging prospects, including improved outcomes and enhanced quality of life, hold promise for individuals with profound hearing loss.

Keywords: cochlear implant; complications; contraindications; hearing loss; outcomes.

The figure illustrates the decline rate (%) in the number of cochlear implant contraindications over 25 years from 1994 to 2019. Each cycle represents a reduction in some contraindications mentioned on the decline curve, starting from 1994, until a complete resolution of all cochlear implant contraindications addressed in the literature by 2019. Additionally, the figure displays the median decline rate, with a 95% confidence interval (15–24 years), after 20 years of investigation, specifically in 2014. This is represented by the vertical dashed line intersecting the x-axis and the decline curve, adjacent to the 50% point on the y-axis.
