The length of the cochlear turns was measured in 9 pairs of temporal bones from age-matched male and female individuals (1 day to 76 years old), using a computer-aided three-dimensional reconstruction and measurement method. The mean cochlear length was significantly longer (Two-way analysis of variance, F = 31.87, d.f. = 1, p less than 0.01) in males (37.1 +/- 1.6 mm) than in females (32.3 +/- 1.8 mm), whereas it did not vary with postnatal age in either sex. Sexually dimorphic cochlear length may pose a new issue in auditory physiology in man. The lack of postnatal elongation also indicates that length of the cochlea becomes close to its maximum during fetal life.
使用计算机辅助三维重建和测量方法，对9对年龄匹配的男性和女性（1天至76岁）颞骨的耳蜗圈长度进行了测量。男性的平均耳蜗长度（37.1±1.6毫米）显著长于女性（32.3±1.8毫米）（双向方差分析，F = 31.87，自由度 = 1，p < 0.01），而在两性中，耳蜗长度均不随出生后年龄变化。耳蜗长度的性别差异可能给人类听觉生理学带来新问题。出生后耳蜗缺乏伸长也表明，耳蜗长度在胎儿期就接近其最大值。
