However, these cannot fully replicate the physiology of the ossicular chain. Pressure fluctuations cause high stresses in rigid passive prostheses, which can result in dislocation, protrusion, and pre\u2010tension in the annular ligament resulting in unsatisfactory hearing results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In collaboration with MED\u2010EL, we developed a new passive middle ear prosthesis that features a balanced, centered ball joint between the headplate and shaft of the prosthesis. We compared the sound transmission properties of this new prosthesis with those of a standard rigid prosthesis. Using Laser\u2010Doppler\u2010Vibrometry, we measured the sound\u2010induced velocity of the stapes footplate relative to a given acoustic stimulus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The new prosthesis showed equivalent sound transmission characteristics compared to the rigid prosthesis, whereas retaining the ability to compensate for pressure fluctuations due to its ball joint.
