From January 2000 to May 2017, 1431 CIs were performed, with 27 (1.9%) undergoing revision surgeries due to device failure. The most common etiology of hearing loss was idiopathic (12/27), followed by...
The most suggestive symptom preceding device failure was intermittent loss of signal. Patients who present with this symptom should undergo electrical examination for suspected device failure. Audiolo...
Cochlear implantation (CI) for deafblindness may have more impact than for non-syndromic hearing loss. Deafblind patients have a double handicap in a society that is more and more empowered by fast co...
In February 2020, Advanced Bionics initiated a field action notice to remove the MS Ultra (V1) implant from circulation. In this study, we quantify a single site's incidence with device failure and ex...

Postoperative speech perception (AzBio sentence test) scores at 12 months postactivation were compared with repeat testing at 6- to 12-month intervals. Degree of change in impedances from 1 month post...
To date, 21% (11/52) of devices have met all three criteria for a confirmed failure with an average decline in speech perception of 27.7 ± 22%. The average length of time for detection of device failu...
Impedance values can be used as a reliable indicator of device malfunction, thus facilitating patient counseling and early intervention. No correlation was identified between impedance changes and spe...

Retrospective case review....
A CI services provider operating across multiple centers....
All patients undergoing CI surgery in a 2-year period between March 2018 and February 2020....
Diagnosis of hearing loss, CI surgery, and subsequent habilitation and mapping....
Distance traveled by patients to their audiological diagnostic, CI surgery hospital, and habilitation sites; subjects' index of relative socioeconomic advantage and disadvantage (IRSAD) and index of e...
n = 201 children and n = 623 adults. There was a significant difference across IRSAD domains for children (p < 0.0001) and adults (p < 0.0001), and IEO in children (p = 0.015) and adults (p < 0.0001) ...
The burden of distance for access to CI in Australia is significant for the upper quartile who may not live within the large city centers. Greater consideration needs to be given regarding barriers to...
