Abstract

Abstract : Objective: The National Institute of Clinical Excellence recommends that adult patients with severe to profound deafness are eligible for simultaneous bilateral cochlear implantation if they are blind or have other disabilities increasing their reliance on auditory stimuli. Cochlear implant (CI) surgery is routinely performed under general anaesthesia (GA), precluding patients who have higher risk associated with GA. Recent literature describes the safety and efficacy of performing unilateral CI surgery under local anaesthesia (LA). We report the first simultaneous bilateral CI under LA in the UK in an adult patient with profound sensorineural deafness and visual impairment. Case study: A 46-year-old gentleman, registered blind, presented with a 20-year history of bilateral progressive hearing loss. He was assessed as unfit for surgery under GA due to significant cardiac comorbidities. We performed simultaneous bilateral CI surgery under LA on the patient; he was discharged home the following day. Postoperative free field audiometry showed a significant improvement; speech discrimination using Bamford, Kowal and Bench sentences presented in quiet, increased from 0% pre-operatively to 100% four months post-operatively. Conclusion: Simultaneous bilateral CI surgery under LA is a safe and feasible procedure for eligible patients who may otherwise have been denied surgery due to their GA risk.
