Learning Objectives: To document the usefulness of VSB placed in the round window in adults with open cavities.
Introduction: The Vibrant Soundbridge (VSB) middle ear implant is a treatment option for patients with a variety of middle ear conditions such as open cavities. The VORP 503 and new couplers have been introduced to expand the possibilities of treatment.
Methods: 12 patients with mixed hearing loss, all with previous middle ear surgery underwent RW vibroplasty. Intraoperative electrocochleography was completed during surgery to ensure the FMT coupling to the RW. Subjective benefit was evaluated using the Nijmegen Cochlear Implant Questionnaire (NCIQ), Glasgow Benefit Inventory (GBI) and Hearing Implant Sound Quality Index (HISQUI29) tests.
Results: RW vibroplasty: mean follow-up was 42mo. Mean functional gain was 34 dB and speech discrimination score at 65 dB (SDS) improved from 14 to 83%. All NCIQ domains improved following surgery. All patients had a positive overall GBI score. The mean quality of sound was defined as “very good”.
Conclusion: The VSB represents a safe and reliable solution of hearing restoration in adults with open cavities suffering from mixed/conductive deafness.
