Abstract
Cochlear implantation (CI) has become an option for the treatment of hearing loss after translabyrinthine resection of vestibular schwannomas. The surgical video presents the case of a 67-year-old male who had translabyrinthine resection of vestibular schwannoma with simultaneous CI and closure with a hydroxyapatite (HA) cement cranioplasty. HA cement cranioplasty can be utilized in place of abdominal fat graft for the closure of translabyrinthine approaches with similar efficacy and complication profile. To the authors’ knowledge, this is the first reported case of a simultaneous CI and translabyrinthine resection of vestibular schwannoma with HA cement cranioplasty.The video can be found here: https://stream.cadmore.media/r10.3171/2021.7.FOCVID211
Highlights
The purpose of this video is to demonstrate the surgical technique regarding translabyrinthine resection of vestibular schwannoma with simultaneous cochlear implantation utilizing a hydroxyapatite cement cranioplasty for closure
Cochlear implantation after vestibular schwannoma removal has been performed previously both as a two-stage and single-stage procedure; there is limited data on simultaneous implantation
The patient’s CNC testing in the affected ear went from 52% to 34%, demonstrating some viable hearing even after translabyrinthine excision. His AzBIO testing in both +10 and +5 signal-to-noise ratio improved from his preoperative state, demonstrating an improved ability to hear in background noise after surgery. This is the first report of simultaneous translabyrinthine vestibular schwannoma resection and cochlear implantation with hydroxyapatite cement cranioplasty
Summary
Cochlear implantation (CI) has become an option for the treatment of hearing loss after translabyrinthine resection of vestibular schwannomas. The surgical video presents the case of a 67-year-old male who had translabyrinthine resection of vestibular schwannoma with simultaneous CI and closure with a hydroxyapatite (HA) cement cranioplasty. The purpose of this video is to demonstrate the surgical technique regarding translabyrinthine resection of vestibular schwannoma with simultaneous cochlear implantation utilizing a hydroxyapatite cement cranioplasty for closure. Gross-total resection was performed, and the cochlear nerve was kept intact throughout the surgery This patient initially presented to the clinic with sudden hearing loss and tinnitus on the right side.
