Methods for counting vestibular ganglion cells and determining the densities of hair cells and intraepithelial basophilic inclusions (IBI) in samples of cross-sectioned vestibular sensory epithelia are described. Data obtained by means of these methods in vestibular sensory epithelia and Scarpa's ganglia in individual temporal bones from subjects at different ages are presented. Both vestibular hair cells and nerve cells in Scarpa's ganglia are found numerically reduced in ears of aged individuals. Changes in the vestibular sensory epithelia appear to precede those seen in Scarpa's ganglion. The incidence of intraepithelial basophilic inclusions correlates with degeneration in the respective vestibular sensory epithelia. There are no striking differences in hair cells densities of the different vestibular sense organs of the same ear and from subjects at about the same age.
本文描述了计数前庭神经节细胞以及测定前庭感觉上皮横断面样本中毛细胞密度和上皮内嗜碱性包涵体（IBI）密度的方法。展示了通过这些方法在不同年龄受试者的颞骨个体中前庭感觉上皮和斯卡帕神经节所获得的数据。在老年个体的耳朵中，发现前庭毛细胞和斯卡帕神经节中的神经细胞数量均减少。前庭感觉上皮的变化似乎先于斯卡帕神经节中的变化。上皮内嗜碱性包涵体的发生率与相应前庭感觉上皮的退变相关。同一只耳朵以及年龄相近的受试者的不同前庭感觉器官的毛细胞密度没有显著差异。
