“…Carefully evaluating the location of the incus and stapes attachment to the piston is crucial during the operation. Although not all individual prostheses can be implanted perpendicular to the stapes footplate at an ideal angle of 90°, the tilting angle of the prosthesis from the direction normal to the stapes footplate was 30 degrees with a fenestration hole of 0.6-mm diameter, with little effect on prosthesis movement and hearing effects (19). In this study, we found that the angle of the incudostapedial joint was 88.29 ± 11.58° (73.97°-121.82°).…”

“…The TBs were prepared for test fitting of the couplers according to the American Society for Testing and Materials (ASTM) standard [F2504-05, Philadelphia, 2005]. An extended mastoidectomy with posterior tympanotomy was performed to expose the middle ear ossicular chain [Gerig et al, 2015;Cuny et al, 2019]. The external ear canal was removed and replaced by an artificial ear canal made of a plastic tube (an inner diameter of 9 mm).…”

Introduction: The Vibrant Soundbridge (MED-EL Medical Electronics, Austria) is an active middle ear implant with a floating mass transducer (FMT) for patients with conductive, sensorineural, or mixed hearing loss. While the FMT is vertically aligned above the stapes head (SH) with the current Vibroplasty Clip coupler (MED-EL Medical Electronics), the new SH coupler was developed to mount the FMT on the inferior side of the stapes and to fit in the reduced middle ear space after canal-wall-down mastoidectomy. Methods: Using 11 human cadaveric temporal bones (TBs), placements of the new SH couplers on the stapes were examined, and effective stimuli to the cochlea were evaluated by measuring piston-like motion of the stapes footplate with a current of 1 mA on the FMT. The results were assessed in comparison with the Vibroplasty Clip coupler. Results: The new SH coupler showed perfect coupling on the stapes in 9 out of 11 TBs. A small gap between the SH and the plate of the connection link part was unavoidable in 2 TBs but had negligible effect on vibrational motion of the stapes. Vibrational motion of the stapes with the new SH coupler was reduced at frequencies above 3 kHz compared to the corresponding motion with the current Vibroplasty Clip coupler, but the relative attenuation over all 11 cadaveric temporal bones was <10 dB. Conclusions: The new SH coupler provides an alternative with more stable fixation when placement of the current Vibroplasty Clip coupler is limited due to insufficient space after canal-wall-down mastoidectomy, while still delivering effective stimuli to the cochlea.
