| Abstract | OBJECTIVE: To compare audiometric and functional outcomes between two designs of heat-activated self-crimping stapes prostheses-a modified shape memory circumferential nitinol-Teflon piston versus its predecessor-in patients with otosclerosis. STUDY DESIGN: A retrospective analysis of preoperative and postoperative hearing thresholds. SETTING: Tertiary referral center and teaching hospital. PATIENTS: One hundred sixty-three consecutive procedures of primary stapes surgery for clinically proven otosclerosis in 108 women and 55 men with an average age of 46 years. INTERVENTION: Stapedotomy and insertion of either a standard or a circumferential stapes prosthesis. MAIN OUTCOME MEASURES: Four-frequency pure-tone average preoperative and postoperative air-bone thresholds were recorded. A secondary outcome measure was stability of the implant, as measured by failure rates. RESULTS: Success of closure of the air-bone gap to within 10 dB was achieved in 97% and comparable in both groups (original prosthesis, 23.6; standard deviation, 7.3, with the average reduction seen in the circumferential prosthesis group being 22.6, standard deviation, 5.6). All the differences were not statistically significant using two-way analysis of variance. Failure rate for the original piston was 6%, with no failures seen with the circumferential piston. CONCLUSION: Both prostheses showed comparable postoperative hearing outcomes, with the circumferential prosthesis being found to be more stable. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
