Objective: To study the hearing results in patients implanted with àWengen titanium clip piston prosthesis after stapedotomy. Methods: In this prospective study, 15 patients of either sex in the age group of 18–50 years having conductive hearing loss with an air-bone gap (ABG) of 30 dB or more, with an intact tympanic membrane, and A or As type of curve in tympanometry were recruited. All patients underwent stapedotomy using àWengen titanium clip piston (Kurz, Germany) which was designed to avoid the scrupulous task of crimping a piston onto the long process of incus. The results were tabulated in accordance with the guidelines set by the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology-Head and Neck Surgery (1994) at frequencies of 0.5, 1, 2 and 3 kHz. The follow-up period was 3 months. Results: The mean preoperative bone conduction (BC) was 16.00 ± 6.02 dB, at 6 weeks postoperative was 16.58 ± 12.40 dB, and at 3 months was 16.00 ± 10.80 dB. The mean preoperative ABG was 42 ± 7.26 dB, at 6 weeks postoperative was 20.5 ± 9.77 dB, and at 3 months was 17.25 ± 10.59 dB. There was improvement in postoperative BC, as well as ABG in 14 patients (except one). Conclusion: The use of the àWengen titanium clip stapes piston gives good results in cases of stapedotomy for otosclerosis. It is easy to insert onto the long process of incus and evades the complex step of crimping. The gain in hearing post surgery is comparable with the other types of pistons reported in literature.
