Objective: To assess the surgical concept and hearing improvement in patients with congenital aural atresia (CAA) using the active middle ear implant (Vibrant Soundbridge®, VBS; Med-EL, Innsbruck, Austria) at the ENT-Clinic Kantonsspital Luzern between 2008 and 2020. Data Sources and Methods: The ENT-statistics database was used to extract information of 8 patients with CAA who underwent Vibrant Soundbridge (VSB) implantation. Two patients had binaural implantation resulting in the analysis of 10 ears. Preoperative audiometric data, CT-scans, the timing of surgery in the overall rehabilitation process, the exact location of the coupling onto the malformed ossicles were compared with postoperative hearing improvement and long-term stability. Results: Whereas the previous Jahrsdoerfer CT classification was not helpful, a careful analysis of the anatomy on CT scans allowed the planning of the coupling once the malformed ossicles were mobilized. In case of microtia repair, the hearing rehabilitation was performed at the second or third stage. There were no complications and no revision surgeries required. Pure tone average (PTA) improved from 64.3 dB to 28.1 dB and CPT-AMA improved from 75.8 % to 15.1 % in hearing loss. Seven out of 8 patients remain daily users of the implants. Conclusion: The implantation of an active middle ear implant type VSB allows in selected cases of CAA an ipsilateral hearing rehabilitation and provides long-term stability in children and adults. Accurate planning and the correct timing are crucial for successful implantation in patients with CAA. |
