The process of disappearance of the stereocilia at the top of the outer hair cell was described by observing aged human cochlea under scanning electron microscope. After loss of hair, remnants of hair could be recognized at the top of outer hair cells. As the process continued, the remnants of the stereocilia increase in percentage, while the remaining abnormal hair decrease. As remnants gradually disappear, the W-configuration faded away. At the same time, the diameter of the hair cell top decreased by shrinking. Before the supporting cells made a complete cover, there may be a depression in the reticular lamina due to shrinking of the top of the hair cell. However, if the depression persists, there is the potential danger of reticular lamina rupture. Existence of a breaking point in the stereocilia of the outer hair cell was proposed.
通过扫描电子显微镜观察老年人耳蜗，描述了外毛细胞顶部静纤毛消失的过程。毛发脱落后，在外毛细胞顶部可识别出毛发残余物。随着这一过程的持续，静纤毛残余物的百分比增加，而剩余的异常毛发减少。随着残余物逐渐消失，W形结构逐渐消失。同时，毛细胞顶部直径因收缩而减小。在支持细胞完全覆盖之前，由于毛细胞顶部收缩，网状板可能会出现凹陷。然而，如果凹陷持续存在，则存在网状板破裂的潜在危险。有人提出外毛细胞静纤毛中存在一个断裂点。
