Hearing loss, an increasing problem across the globe, results in an important solution in the form of cochlear implants, highlighting the critical need for effective interventions. This review involves analyzing 46 relevant publications via databases such as PubMed and Google Scholar, providing current insights into pre-operative issues. Studies through databases such as PubMed and Google Scholar, ensuring contemporary insights into the pre-operative considerations. The pre-operative evaluation encompasses medical history, covering prenatal events and immediate post-natal health, along with physical examinations and complete audiometric assessments. High-Resolution Computed Tomography (HRCT) and Magnetic Resonance Imaging (MRI) emerge as crucial imaging techniques, guiding surgical planning and electrode placement. Brainstem Evoked Response Audiometry (BERA) supplements inconclusive MRI data, while vestibular screening aids in candidate selection. Cochlear duct length determination, often assessed through imaging techniques, contributes to optimal electrode array selection. Models in cochlear implant research, spanning computational, animal, tissue engineering, and physical models, further enhance our understanding and refinement of cochlear implant designs. In conclusion, this comprehensive pre-operative workup plays a significant role in assessing patient health, identifying causes of deafness, and contributing to the overall success of cochlear implantation, a transformative solution for profound hearing impairment.
