Bone Conduction Threshold Measurements in Patients with Bone Conduction Devices: A Comparison of Available Methods.

Background: The semi-implantable bone conduction devices connect the skull to the hearing device by means of an implant. This implant affords us 3 possible methods for conducting bone conduction evaluation, which may produce a different result for the same patient, and comparisons of results from different centers may therefore be interpreted incorrectly. Thus, the authors attempt to quantify the audiometric differences between the obtained auditory results and to check whether the results of standard pure tone audiometry could be replaced with the results obtained by alternative measurement methods.
