Mechanical Energy Dissipation Through the Ossicular Chain and Inner Ear Using Laser Doppler Vibrometer Measurement of Round Window Velocity

Conclusions: This study supports the concept that round window transfer function is equivalent to stapes footplate transfer function when subjected to the same acoustic stimuli. This study also demonstrates that the round window is a much more difficult target to measure when using LDV technology and improvements in experimental design are required to better understand round window physiology in relation to transfer of acoustic vibratory stimulus transferred throughout the middle ear. A complete and thorough understanding of the biophysical properties of the middle and inner ear are critical for optimal ossiculoplasty outcomes and the development of future ossicular prosthetics.
