Experience with the Vibrant Soundbridge RW-Coupler for round window Vibroplasty with tympanosclerosis

چکیده
Abstract Usage of the Vibrant Soundbridge (VSB) with round window (RW)-Coupler placement at the RW has been shown to successfully treat mixed hearing loss. Coupling between the VSB's floating mass transducer (FMT) and the RW membrane is difficult in the case of sclerosis in the RW and drilling down the bony lip until the RW membrane can be seen completely can possibly induce a perilymphatic fistula. A 68-year-old woman who had bilateral mixed hearing loss with sclerosis in the RW due to tympanosclerosis underwent a RW-Vibroplasty with a RW-Coupler. Speech discrimination scores in quiet and noise and functional gain with the VSB with RW-Coupler were better than those using a conventional hearing aid. The results of the present case have shown the feasibility of implanting a VSB with RW-Coupler in patients with mixed hearing loss due to tympanosclerosis.

A Case of the Vibrant Soundbridge Stapes Coupler in Patients with Mixed Hearing Loss
The Vibrant Soundbridge (VSB) with stapes clip coupler placement at the stapes head has been used successfully to treat mixed hearing loss. Coupling between the floating mass transducer of the VSB and the stapes head is technically less demanding than incus vibroplasty and is more likely to generate a positive outcome without significantly changing residual hearing or resulting in medical or su...

متن کاملAn optical coherence tomography study for imaging the round window niche and the promontorium tympani
Tympanosclerosis may involve the tympanic membrane, the ossicles, as well as the oval and round window niche, respectively. The surgical treatment of the obliterated oval window niche is most challenging. Beside stapesplasty, vibroplasty with coupling the floating mass transducer (FMT) onto the round window niche and into a new, so-called third window is indicated. In the latter situation, dril...

OBJECTIVE To measure the Quality of Life outcomes and impact on tinnitus perception in a group of patients after Round Window Vibroplasty (RW-VSB) for mixed or conductive hearing loss. STUDY DESIGN A single-subject, repeated measures design was employed. All VSB fittings were based on hearing thresholds results and were not set to mask tinnitus. METHODS Ten Round Window-Vibroplasty patients...
متن کاملActive middle ear implant coupled bilaterally to the round window despite bilateral implanted stapes prostheses.
After stapes surgery, patients with mixed or moderate hearing loss have limited possibilities for hearing improvement. We are reporting on a patient who underwent stapedotomy bilaterally 20 years ago and had sensorineural and mixed hearing loss. Recurrent otitis externa prevented the use of hearing aids. This patient was treated bilaterally with the Vibrant Soundbridge (Med-El, Innsbruck, Austr...
