Objective: To compare the performance of the Nitinol piston with the conventional Teflon piston. Methods: Conducted from the perspective of a retrospective study, this investigation focused on patients in public healthcare firms in a Vietnamese context. Particularly, the study examined the participants’ medical records. The inclusion criterion was set in such a way that the participants were expected to have had pathologically and surgically confirmed otosclerosis diagnosis. From the perspective of the exclusion criterion, medical records of patients who might have been lost to follow-up, those who had insufficient audiometric data, and those who exhibited revision surgery were not considered for analysis. Also, this investigation focused on prosthesis lengths that stretched from 4.00 millimeters to 4.50 millimeters. Also, the diameter of the target prostheses was expected to range from 0.40 millimeters to 0.60 millimeters. Results: Findings from the conventional Teflon piston group revealed 26.1900 ± 6.7600dBHL while the outcomes for the case of the Nitinol piston participants stood at 26.7900 ± 8.3300dBHL. The postoperative ABG average was also investigated for both groups. Regarding the Nitinol group, findings depicted values of 7.9200 ± 6.7500dBHL. At P = 0.018, results for the preoperative stage for this group stood at 26.7900 ± 8.3300dBHL. As such, it was concluded that the Nitinol piston group’s preoperative ABG average was significantly larger than the postoperative ABG average. Conclusion: In summary, this study’s results revealed that the success of stapes surgery depends on the accuracy of the prosthesis loop’s crimping. From a data management perspective, the comparison of the performance of the conventional Teflon piston with that of the Nitinol piston suggests distinct advantages with the use of the Nitinol shape-memory prosthesis. Hence, the Nitinol piston forms a more effective, safer, and easier treatment option that could be applied to clinical or medical interventions such as those involving otosclerosis surgeries.
