These radiologic measurements demonstrate normal variations seen in round window anatomy relative to facial recess approach and bony tympanic annulus, providing a baseline to assess …

(iii) Phase differential between cochlear windows. The fluids in the inner ear are usually incompressible. The round window vibrates in the opposite phase to the oval window, allowing …
