Technology and clinical use of inert/bioactive ceramic ossicular prosthesis in the medium ear

摘要

A sampling of patients submitted in the past to a restoration of their auditory functionality in the framework of a planned experimental surgery, with use of different surgical techniques and materials, was recently checked to have a follow-up not lower than 5 years. A complete series of tests on their auditory functionality has allowed the formulation of statistical data on the behaviour of the different materials adopted over time. A wide comparison of the results is critically reported. Very interesting results come from the cases where alumina prostheses, with the brim covered with biological glass AP40, were adopted.
