Effect of Endolymphatic Hydrops on Sound Transmission in Live Guinea Pigs Measured with a Laser Doppler Vibrometer

Figure 3

Mean HR value of each turn in the EH models. (a) HR was measured by the area of SM and SV. SM means the scala media, SV means scala vestibule, and ST means scala tympani. (b) Subapical turn had developed the most prominent hydrops with a mean HR value of 3.34, secondly followed by suprabasal turn. Mean HR values of all the turn are larger than 1 (dotted line: an indicator of no EH existence).
