“…Only one case was reported in our survey where a surgical procedure was required for reimplantation of a device: a recipient of the SOUNDBRIDGE VORP 503 implant was scanned with a 0.2 T MRI even though this middle ear implant has only been approved for use at 1.5 T and not at 0.2 T. Todt et al reported that a 1.5 T MRI was performed on SOUND-BRIDGE VORP 503 users. All scans were performed without any degree of pain, change in pure tone audiometry results, or audio processor fittings [34]. Several studies have documented cases in which recipients of the SOUND-BRIDGE had an MRI at a magnetic field strength for which the SOUNDBRIDGE is not approved, yet no adverse events or complications were reported [16,[29][30][31].…”

Purpose Magnetic resonance imaging (MRI) is often used to visualize and diagnose soft tissues. Hearing implant (HI) recipients are likely to require at least one MRI scan during their lifetime. However, the MRI scanner can interact with the implant magnet, resulting in complications for the HI recipient. This survey, which was conducted in two phases, aimed to evaluate the safety and performance of MRI scans for individuals with a HI manufactured by MED-EL (MED-EL GmbH, Innsbruck, Austria). Methods A survey was developed and distributed in two phases to HEARRING clinics to obtain information about the use of MRI for recipients of MED-EL devices. Phase 1 focused on how often MRI is used in diagnostic imaging of the head region of the cochlear implant (CI) recipients. Phase 2 collected safety information about MRI scans performed on HI recipients. Results 106 of the 126 MRI scans reported in this survey were performed at a field strength of 1.5 T, on HI recipients who wore the SYNCHRONY CI or SYNCHRONY ABI. The head and spine were the most frequently imaged regions. 123 of the 126 scans were performed without any complications; two HI recipients experienced discomfort/pain. One recipient required reimplantation after an MRI was performed using a scanner that had not been approved for that implant. There was only one case that required surgical removal of the implant to reduce the imaging artefact. Conclusion Individuals with either a SYNCHRONY CI or SYNCHRONY ABI from MED-EL can safely undergo a 1.5 T MRI when it is performed according to the manufacturer’s safety policies and procedures.

“…In 2014, VSB model 503 was released, which does not have a titanium clip embedded in the FMT but has a variety of couplers. 292 , 297 This model allows the FMT to be placed on the short process of the incus, facilitating surgery. Other couplers were developed both for the round window and to aid ossiculoplasty, and they can also be adapted to a partial or total ossicular replacement prosthesis in middle ear surgery.…”

“…Currently, new couplers allow the FMT to be placed on the short process of the incus, stapes superstructure, and round window. 96 VSB model 503 supports up to 1.5 Tesla MRI, 97 whereas earlier models are incompatible with MRI. Bone conduction thresholds to indicate VSB in conductive hearing loss are 45 dB (500 Hz), 50 dB (1000 Hz), and 65 dB (2000 and 4000 Hz).…”

Abstract: In this series, 1.5T magnetic resonance imaging scans were performed with the Vibrant Soundbridge 503 without complications. Limitations persist in terms of magnetic artefacts.
