The NiTiBOND prosthesis allows early results to be obtained similar to those with a manually crimped prosthesis fitted by experienced surgeons, thus reducing the learning curve in this critical step of the procedure.
To analyze the 1-month results using the nitinol NiTiBOND prosthesis in primary otosclerosis surgery and to compare the results with those obtained with fully fluoroplastic or fully titanium pistons.
Fifty consecutive cases operated on with the NiTiBOND prosthesis (nitinol group) were compared with 50 cases operated on with a fully fluoroplastic piston (fluoroplastic group), and with 131 cases operated on with a fully titanium piston (first titanium group), and also with 50 cases operated on with the same titanium piston just before using the NiTiBOND piston (last titanium group). Pure-tone and speech audiometry was performed 1 month after surgery for the nitinol group. Comparison was made between the early hearing results of the four groups.
The mean air-bone gap closure for the nitinol group was 16 ± 1.0 dB (mean ± SEM, n = 50); an air-bone gap of <15 dB and <10 dB was obtained in 100% and 84% of cases, respectively. These hearing results were similar to the last titanium group and significantly better than those observed in the fluoroplastic and first titanium groups.
镍钛键合假体能够获得与经验丰富的外科医生手动压接的假体相似的早期效果，从而减少该手术关键步骤中的学习曲线。
分析在原发性耳硬化症手术中使用镍钛诺镍钛键合假体的1个月结果，并将结果与使用全氟塑料或全钛活塞获得的结果进行比较。
将连续50例使用镍钛键合假体手术的病例（镍钛诺组）与50例使用全氟塑料活塞手术的病例（氟塑料组）、131例使用全钛活塞手术的病例（第一钛组）以及在使用镍钛键合活塞之前使用相同钛活塞手术的50例病例（最后钛组）进行比较。镍钛诺组在术后1个月进行纯音和言语听力测定。对四组的早期听力结果进行比较。
镍钛诺组的平均气骨导间距闭合为16±1.0dB（平均值±标准误，n = 50）；分别有100%和84%的病例气骨导间距<15dB和<10dB。这些听力结果与最后钛组相似，且明显优于氟塑料组和第一钛组。
