Highlights

Ossicular chain reconstruction remains the primary method of restoring conductive hearing deficits commonly seen in chronic middle ear disease [2,3]
In comparison to the Bell prosthesis which was successful in 82% of patients (n=14) (p< 0.001)
One revision OCR in the Bell cohort was needed as it extruded, subsequently it was replaced with a Clip-Piston Dresden prosthesis (Clip) prosthesis

Summary

Introduction

Ossicular chain reconstruction remains the primary method of restoring conductive hearing deficits commonly seen in chronic middle ear disease [2,3]. Since 1994, the German company Kurz has developed different forms of titanium ossicular prostheses. The earlier style Bell prosthesis (Bell) was designed as a partial ossicular replacement prosthesis (PORP) to be placed on the intact stapes capitulum (Figure 1). Clip-Piston Dresden Prosthesis (Clip) which features a springloaded fastening mechanism to secure the coupling to a mobile stapes (Figure 2). The design is reported to reduce dislocation and extrusion of prosthesis with superior audiological outcomes. The purpose of this study is to compare postoperative audiological outcomes and complications of the Clip prosthesis with the Bell prosthesis
