A surgical technique for implantation of the vibrant soundbridge middle ear implant in dogs

Abstract

OBJECTIVE: To report a surgical implantation of the Vibrant Soundbridge (VSB) middle ear implant in dogs. STUDY DESIGN: Pilot study. ANIMALS: Dogs (n=3). METHODS: A lateral approach to the tympanic bulla was used to insert the floating mass transducer of the VSB into the tympanic bulla. Using microscopic guidance the transducer was moved to and inserted into the round window niche by manipulation through the acoustic bony meatus, after reflection of the tympanic membrane. VSB position was confirmed by computed tomography (CT) imaging. RESULTS: No intraoperative complications occurred and CT images confirmed correct placement of the VSB. CONCLUSIONS: A VSB can be safely implanted in the middle of dogs.
