The measurements of areas of the scala tympani (mm²) in four cochleae

Cochleaes	The basal turn	The second turn	The third turn
1	2.45	0.093	0.064
2	2.46	0.094	0.062
3	2.43	0.096	0.065
4	2.42	0.093	0.069
Average	2.44	0.094	0.065

Four cochleae were examined to measure the area of the scala tympani. The images of modiolus histological sectionsby light microscope (Olympus SZX10) were imported into the Mimics software 17.00 in JPEG format, then measured the scale length and the cross-areas of scala tympani of every turn by its measuring kit directly four times.
