BACKGROUND: Functional simulation of middle ear reconstruction is a valuable tools for training in otosurgery. We introduce a new experimental model which provides a direct acoustic feedback of the functional quality of ossicular chain reconstruction.
METHOD: In this model the tympanic membrane and the ossicular chain have to be reconstructed for proper sound transmission to an artificial inner ear receptor. The received signal is converted into acoustic information and consecutively provided via headphone.
RESULTS: Any changes in the reconstruction (e. g. tilting the prosthesis) can be experienced online and immediately optimized by the surgeon or a trainee.
CONCLUSION: The experimental model can be used for demonstration and training in otosurgery. This model is also suitable for comparing measurements of transfer functions in a calibrated version and can be applied to development and critical evaluation of middle ear prostheses.
