[Individualized implant selection for an anatomically normal cochlea : Cochlear implant surgery on the way to personalized medicine].

BACKGROUND

Due to the anatomical variety of the human cochlea and the many factors that may determine the choice of the cochlear array, there is no one-size-fits-all method for determining the right implant. The cochlear size, preoperative residual hearing, anatomical variants, operative technique, and cause of deafness must be taken into consideration when making this decision.

OBJECTIVE

This work aims to spread awareness of precision surgery and provide an overview.

MATERIALS AND TECHNIQUES

Factors that contribute to individualization are explained, and future advances are outlined.

RESULTS

The optimum treatment, if possible, is electroacoustic stimulation. Cochlear coverage of approximately 80% should be the goal when using electrical stimulation alone.

CONCLUSION

In order to maximize rehabilitation results, recent developments in cochlear implantation mark a paradigm shift away from standardized treatments and toward individualized therapy.
