WebbAn association of round window atresia and congenital stapes fixation is apparent. The mechanism of the conductive hearing loss following stapedectomy remains poorly … WebbAs the sound wave energy moves the ossicles-stapes footplate at the oval window, the round window membrane moves in an opposite phase to the movements of the oval window dissipating the sound energy. This mechanism allows the incompressible fluid in the cochlea to move causing movement of the basilar membrane which stimulates the …
WebbThe passage of vibrations through the air across the middle ear from the tympanic membrane to the round window is of negligible importance. Thanks to these mechanical features of the middle ear, the hair cells of the normal cochlea are able to respond, at the threshold of hearing otosclerosis, which causes the stapes footplate to become fixed ... Webb(b) The stimulus pressure incident upon the stapes-footplate boundary in the cochlea due to reverse-drive stimulation of the round window (RW), p þ c , encounters the Z st impedance and a ...
