Abstract

Sato et al. [Acta. Otolaryngol. 111 (6), 1037-1040 (1991)] reported that the human cochlea is, on average, 15% longer for males than females. This corresponds to 4.7 mm in length and to 2.78 standard deviations (SD). Anatomical measurements of the lengths of cochleas from 148 heads (194 cochleas) from eleven sources are reviewed and summarized. A sex difference of 3.36% is observed. This corresponds to 1.11 mm in length and to 0.49 SD. The mean lengths of the male and female cochleas are approximately 34 and 33 mm, respectively, and the population SD is 2.28 mm. The statistical significance of the observed difference is questionable.

摘要

佐藤等人[《耳鼻咽喉学报》111(6)，1037 - 1040(1991)]报告称，人类耳蜗平均而言，男性比女性长15%。这相当于长度为4.7毫米，标准差为2.78。对来自11个来源的148个头部（194个耳蜗）的耳蜗长度进行了解剖测量，并进行了综述和总结。观察到性别差异为3.36%。这相当于长度为1.11毫米，标准差为0.49。男性和女性耳蜗的平均长度分别约为34毫米和33毫米，总体标准差为2.28毫米。所观察到的差异的统计学意义值得怀疑。
