NiTiBOND, eine optimierte Steigbügelprothese zur chirurgischen Behandlung der Otosklerose

Purpose Otosclerosis leads to a fixed stapes footplate and thus to hearing loss. The predominant treatment method is surgery, with various types of stapes prostheses available. The aim of this study was to investigate the safety and efficacy of the new mAXIS Stapes Prosthesis. Methods 34 cases of otosclerosis were implanted with the new mAXIS Stapes Prosthesis. Comprehensive clinical assessments, including pre- and postoperative pure tone audiometry was performed at short-term (ST) follow-up at 25 (± 15) days and mid-term (MT) follow-up at 181 (± 107) days. The pure tone average of 0.5, 1, 2 and 3 kHz (PTA4) was calculated. Results In all cases, the application of the prosthesis was successful and straightforward. The postoperative PTA4 air-bone gap was 10.7 ± 5.2 dB at ST follow-up (n = 34) and 8.3 ± 4.1 dB at MT follow-up (n = 18). In 61% of cases, the ABG-closure was within 10 dB and in 100% of cases within 20 dB at MT follow-up. Conclusion Findings of this study support that the mAXIS Stapes Prosthesis is safe for implantation and shows promising audiological outcome. Future investigations will contribute its long-term efficacy and safety profile.

Otosclerosis is an important condition for the otorhinolaryngologist, and often in (differential) diagnosis and therapy challenging disease. Although a causal therapy option does not exist until today, if the diagnosis is correct, an operative or apparative hearing rehabilitation with very high chances of success can be promised. In addition to hearing aids surgical treatment with passive implants as a standard therapy, and in special cases also the implantation of active middle ear implants or cochlear implants, in advanced otosclerosis with significant involvement of the inner ear, are of importance. Knowledge of the definition, pathogenesis, diagnostics and in particular of the differential diagnosis as well as the current conservative and operative therapeutic limits are indispensable for the indication and selection of the optimal treatment path.In a two-part presentation, the current specialist medical knowledge of the disease in diagnosis and therapy is summarized. In addition to modern diagnostic procedures, aspects of therapy and prognosis are considered in a second article. This article therefore primarily refers to continuing education for residents in training and for young specialists.
