A total of 1000 human temporal bones were studied to determine the prevalence of two microfissures: 1. the one between the facial canal and the vestibule, 2. the microfissure between the round window niche (RWN) and the posterior semicircular canal (PSC). Additionally, this study compares the prevalence according to temporal bone age and sex. The microfissure between the facial canal and the vestibule was observed in 470 (47%) temporal bones, with a bilateral presence of 77.2%. The prevalence of this microfissure increases linearly with age. It was not found in any bone within the 0 to 2 age group. It was present in 3 (7.3%) bones from the 2 to 9 age group, as opposed to 374 (54.8%) bones from the 40 and over group. The microfissure between the RWN and the PSC was detected in 915 (91.5%) temporal bones. This second microfissure was found to be an overwhelmingly bilateral entity. The prevalence of this other microfissure also increases with age. This microfissure was also not present in any temporal bone within the 0 to 2 age group. It was found in 28 (68.3%) bones from the 2 to 9 age group, in contrast to 678 (99.4%) temporal bones from the 40+ group.
共研究了1000块人类颞骨，以确定两种微裂隙的发生率：1. 面神经管与前庭之间的微裂隙；2. 圆窗龛（RWN）与后半规管（PSC）之间的微裂隙。此外，本研究还比较了根据颞骨年龄和性别的发生率。面神经管与前庭之间的微裂隙在470块（47%）颞骨中被观察到，双侧出现率为77.2%。这种微裂隙的发生率随年龄呈线性增加。在0至2岁年龄组的任何骨骼中均未发现。在2至9岁年龄组的3块（7.3%）骨骼中存在，而在40岁及以上年龄组的374块（54.8%）骨骼中存在。RWN与PSC之间的微裂隙在915块（91.5%）颞骨中被检测到。发现这第二种微裂隙绝大多数为双侧性。这种微裂隙的发生率也随年龄增加。在0至2岁年龄组的任何颞骨中也未发现这种微裂隙。在2至9岁年龄组的28块（68.3%）骨骼中发现，而在40岁以上年龄组的678块（99.4%）颞骨中发现。
