Background <p>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.</p> Objective <p>This work aims to spread awareness of precision surgery and provide an overview.</p> Materials and techniques <p>Factors that contribute to individualization are explained, and future advances are outlined.</p> Results <p>The optimum treatment, if possible, is electroacoustic stimulation. Cochlear coverage of approximately 80% should be the goal when using electrical stimulation alone.</p> Conclusion <p>In order to maximize rehabilitation results, recent developments in cochlear implantation mark a&#xa0;paradigm shift away from standardized treatments and toward individualized therapy.</p>
