Variations in microanatomy of the human cochlea.

Avci E, Nauwelaers T, Lenarz T, Hamacher V, Kral A - J. Comp. Neurol. (2014)

Bottom Line: At the lateral region, the height decreased significantly at the beginning of the second turn.We found a correlation between the length of the RC and that of the ST.These differences could have considerable implications for approaches to the design of CI arrays, especially in terms of their ability to preserve residual hearing during insertion of the electrode array.

The average sectional area (aSA; black-dotted) and individual sectional area (SA; colored) as a function of the angular distance. The aSA increased within the first 20°, and subsequently continuously decreased until the end of the second cochlear turn. RW, round window.

fig09: The average sectional area (aSA; black-dotted) and individual sectional area (SA; colored) as a function of the angular distance. The aSA increased within the first 20°, and subsequently continuously decreased until the end of the second cochlear turn. RW, round window.

Mentions: The average sectional area (aSA) followed a similar pattern as the aCSD. Within the first 20°, the aSA reached a maximum of 2.3 mm2, and decreased until the end of the second cochlear turn to 0.6 mm2 (Fig. 9). The variability of the SA between each of the scalae was higher compared with the CSD (14–24 %). TB06 and TB11 represent the ST with smallest and largest aCSD and aSA.
