Computer-assisted three-dimensional reconstruction was performed from histologic sections of the left temporal bone removed from a case of E trisomy syndrome. The reconstructions included structures such as the bony and membranous labyrinths, ossicles, ossicular muscles, tympanic membrane, and facial and eighth nerves. The structures could be observed individually or simultaneously in combination. Prominent abnormalities observed in these reconstructions included enlargement of the utricle, absence of the posterior semicircular canal, slight hypoplasia of the cochlea, anomaly of the stapes, abnormally shaped stapedius muscle, abnormal course of the facial nerve, and flattening of the tympanic membrane. The results were useful for the visual and stereoscopic understanding of abnormal configurations and the spatial orientations of these abnormalities.
对一例18-三体综合征患者切除的左侧颞骨组织切片进行了计算机辅助三维重建。重建结构包括骨迷路和膜迷路、听小骨、听骨肌、鼓膜以及面神经和第八对脑神经等。这些结构可以单独观察，也可以组合起来同时观察。在这些重建中观察到的显著异常包括椭圆囊扩大、后半规管缺如、耳蜗轻度发育不全、镫骨异常、镫骨肌形态异常、面神经走行异常以及鼓膜扁平。这些结果有助于直观和立体地理解异常形态以及这些异常的空间取向。
