Abstract
Since the cochlear implant surgery{u2019}s approval as a treatment for profound bilateral sensory neural hearing loss by the United states{u2019} FDA in the middle of the 80s there has been many advances, it could be argued that everything about the implantation surgery has changed within the last 10 years. Starting from the technique of the insertion of the electrode into the scala tympani to more advanced approaches including a complete trans canal approach to the insertion of the implant electrode, all aiming at minimalizing the effect the surgery has on the patient and less traumatic techniques to conserve any residual hearing in the ear. No one can argue that the socioeconomic effect the surgery has on the patients is huge as it is an ongoing process and needs a lot of effort and time from the patient and the parents. For a perfect surgery can be easily ruined by the subsequent events in later years. Our study was a retrospective study on 195 patients implanted in Kasr el Aini hospitals cochlear implant unit in the period starting January 2014 until the end of December 2018. There was a wide variety of implants provided by Med-El and Advanced bionics for the surgery. All our patients suffering from hearing loss had pure tone audiometry thresholds of around 100 dB on the 500, 1000, 2000 and 4000 Hz which made their oral communication impossible. But after the surgery the patients had an Aided pure tone audiometry threshold of 39, 41, 39 and 38 dB in the mentioned frequencies
