Abstract

Objective: This paper reviews the outcomes of partial ossicular chain reconstruction using the Kurz Clip-Piston Dresden prosthesis (Clip) in comparison to the earlier generation Bell prosthesis (Bell).

Study design: A retrospective monocentric chart review.

Subjects and Methods: All patients undergoing ossicular chain reconstruction between 1 January 2014 and 31 December 2018.

Results: Forty-three patients, 7 children and 35 adults were included in the study. A successful hearing result was defined as ABG <20 dB [1]. A total of 91% of cases resulted in an overall successful hearing. The overall PTA improved by 20 dB +/- 0.63 (preop: 52.6 +/- 19, postop: 32.6 +/- 14.8). The overall ABG improvement was 33.9 +/- 11.4 (preop: 13 +/- 7.6, postop: 20.7 +/- 3.8). The overall results of Clip being better (96%) than the results for Bell prosthesis (82%). A successful postoperative ABG of <20 dB was obtained in 91% of the patients (n=39). The Clip prosthesis had a significantly higher success rate of 96% (n=26) in comparison to the Bell prosthesis which was successful in 82% of patients (n=14) (p< 0.001). Results showed a low complication rate. One revision procedure (2.3%) to modify the length was needed with a Clip prosthesis and one revision procedure was required in the Bell group due to extrusion; it was replaced with a Clip prosthesis

Conclusion: Clip prosthesis demonstrates promising outcomes partial ossicular chain reconstruction with higher rates of postoperative air-bone Gap reduction and minimal complications.
