- Abstract
Objective: To statistically analyse the hearing thresholds of two cohorts undergoing stapedotomy for otosclerosis with two different prostheses. Method: A retrospective study was conducted comparing NiTiBOND (n = 53) and Nitinol (n = 38) prostheses. Results: Average follow-up duration was 4.1 years for NiTiBOND and 4.4 years for Nitinol prostheses. The post-operative air–bone gap was 10 dB or less, indicating clinical success. The p-values for differences between (1) pre- and post-operative values in the NiTiBOND group, (2) pre- and post-operative values in the Nitinol group, (3) pre-operative values and (4) post-operative values in the two groups were: air–bone gap – p < 0.001, p < 0.001, p = 0.631 and p = 0.647; four-frequency bone conduction threshold – p = 0.076, p = 0.129, p < 0.001 and p = 0.005; four-frequency air conduction threshold – p < 0.001, p < 0.001, p = 0.043 and p = 0.041; three-frequency (1, 2 and 4 kHz) bone conduction threshold pre-operatively – p = 0.639, p = 0.495, p = 0.001 and p = 0.01; and air conduction threshold at 4 kHz: – p < 0.001, p < 0.001, p = 0.03 and p = 0.058. Conclusion: Post-operative audiological outcomes for NiTiBOND and Nitinol were comparable.
