Introduction: Otosclerosis is a primary metabolic localized disease characterized by conductive deafness. The mainstay of treatment of this condition remains surgical. Several techniques and approaches are commonly used with largely excellent results. A newly developed piston made of Nitinol has the property of crimping by heat activation rather than manually. This study, carried out at a tertiary care centre of the armed forces, proposed to evaluate the efficacy and complications of the Nitinol Smart piston in comparison to the conventional pistons currently being used. Methods and Materials: 50 patients of otosclerosis were evaluated with Pure tone audiometry and randomized into test and control groups of 25 each. The control group underwent stapedotomy by the conventional Teflon piston and in the test group Nitinol smart pistons were used. Pure tone Audiometry for hearing thresholds and AB gap was performed at 06 weeks after surgery and repeated at 06 months, 01 year and 02 years after surgery. Results: Results show an almost identical outcome in terms of improvement of hearing thresholds with the two kinds of prosthesis used with the 'Smart' piston showing marginally better results. There was no significant difference in the postoperative ABG (P < .23) or ABG closure (P < .09). Conclusion: The nitinol piston prosthesis represents the latest advancement in stapes prosthesis design in that incorporates heat-sensitive crimping to preclude the technically difficult step of manual crimping. It is at least as effective as a standard prosthesis in closing the ABG in patients with otosclerosis.
