Abstract/OtherAbstract:
This paper presents the results of non-contact measurements of the human ear round window (RW) membrane motion in freshly harvested human cadaver temporal bone specimens. A PSV 400 Scanning Laser Vibrometer system (Polytec, Waldbronn, Germany) was used to determine the effect of stapedotomy on the sound-induced displacement amplitude of the RW membrane. The vibration patterns were measured in the frequency range of 0.4-10 kHz in four specimens with air conduction stimulation at 90 dB SPL applied to the external auditory canal. It was shown that the vibration amplitude of the RW membrane after stapes piston prosthesis implantation, in comparison with a physiological specimen, was reduced several times. The motion of the RW membrane can be used to determine the cochlear stimulation for the evaluation of middle ear ossicle reconstruction, especially in the case of otosclerosis surgery.
