Integrity testing is an in-vivo test that assesses the implant functionality and is used when device failure is suspected. In the last 15 years, integrity testing was performed in 11% of all devices implanted in children. Clinical performance problems, i.e. lack of progress, were the main reason to perform integrity testing in children, followed by technical and auditory problems. Twenty-five devices were explanted and in two cases integrity testing failed to identify device malfunction. Integrity testing is a valuable clinical tool and should be considered when there is a clinical concern about lack of progress in children who might not have the language skills to communicate device related problems, although a multi-disciplinary clinical decision has to prevail despite integrity test results.
