Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <sec> <title>Objectives</title> <p>To determine the incidence of abnormal radiological findings after cochlear implantation and their effect on clinical outcomes.</p> </sec> <sec> <title>Methods</title> <p>Retrospective review of 220 adult cochlear implants. Clinical records and post-operative plain X-rays were reviewed and compared with pre-operative and 6-month post-operative City University of New York (CUNY) speech scores.</p> </sec> <sec> <title>Results</title> <p>There were no cases of extra-cochlear array misplacement. Imaging showed 20 cases of incomplete array insertion (9.2%), 3 cases of kinking of the array (1.4%), 2 cases of tip rollover (0.9%), and 1 case of apparent array fracture (0.5%). Patient management was not altered by abnormal imaging. Patients with abnormal radiological findings had slightly minor improvements (median 39 vs. 56%) in City University of New York (CUNY) speech discrimination scores at 6 months (Mann–Whitney <italic>U</italic> test, <italic>P</italic> = 0.043).</p> </sec> <sec> <title>Conclusion</title> <p>All abnormalities on post-operative imaging were minor and did not alter patient management. The future role of post-operative imaging is discussed.</p> </sec> </abstract>
