Summary :
Introduction: Jervell and Lange-Nielsen syndrome is a rare inherited disorder that associates cardiac abnormality with a profound bilateral deafness. Objectives: Our aim is to conduct a retrospective evaluation of the management of the patients in our cochlear implantation center and to review it together with the literature. Materials and methods: We have conducted a retrospective and analytic study. We have studied the epidemiological characteristics, pre/per and post-operative care and the evolution of these patients. Results: A 0.33% (3/900) of the all patients who has been implanted in our centre had the Jervel and Lange-Nielsen Syndrome. All patients had preoperative ECG before undergoing surgery. No cardiac incidents have been described during surgery and after. All patients were under b-blockers, and only those 3 implanted are well integrated in the normal school system twelve years after. They present mutations on the KCNQ1 and KCEN1 genes. Conclusion: Cochlear implantation is well performed in patients with Jervell and Lange-Nielsen syndrome. Early diagnosis and an appropriate medical treatment have changed mortality. Our experience shows that when cardiac problem is under control, cochlear implantation in patients with Jervell and Lange-Nielsen syndrome is same to a child not suffering this syndrome and improves quality of life.
