BACKGROUND: Cochlear implantation is a safe surgery for restoration of hearing in severe to profound cochlear hearing loss candidates. Patients with congenital cochlear hearing loss may at times have renal anomalies. Renal dysfunction can contribute to sensorineural hearing loss, and it can affect cochlear implantation in a variety of ways, from minor intraoperative issues to major life-threatening complications.
Our study aimed to determine the prevalence of renal association encountered in cochlear implantees over a period of 15 years (Jan 2000–Dec 2014) at our centre; secondly to classify these renal associations, as this has an effect on management; and finally to suggest a protocol for perioperative management of cochlear implantees with renal comorbidity.
MATERIAL AND METHODS: This is a retrospective study of 1000 consecutive patients who underwent cochlear implantation at the Madras ENT Research Foundation (Chennai) over the period Jan 2000–Dec 2014. All cochlear implantees with bilateral severe to profound cochlear hearing loss and associated renal associations were included. The data for our study were collected from nephrologist referral forms and medical records. The paper gives a nephrologist’s perspective on perioperative care to be given during cochlear implantation. Relevant literature is reviewed.
RESULTS: Overall prevalence of renal disease was 6 out of 1000 implantees (0.6%) in our series. We classify the associated renal associations in cochlear implant candidates into 4 categories, and appropriate management for them is described.
CONCLUSIONS: A protocol for evaluating renal associations as they affect cochlear implantation has been designed, and the optimal management of these issues has been discussed.
