Auditory ossicular sections were scanned at section thicknesses (mm)/section interspaces (mm) of 1.5/1.5 (61 patients), 1.0/1.0 (13 patients) or 1.5/1.0 (33 patients). At any type of section thickness/interspace, the malleal and incudal structures were observed with almost equal frequency. The region of the incudostapedial joint and each component part of the stapes were shown more frequently at a section interspace of 1.0 mm than at 1.5 mm. The visualization frequency of each auditory ossicular component on two or more serial sections was investigated. At a section thickness/section interspace of 1.5/1.5, the visualization rates were low except for large components such as the head of the malleus and the body of the incus, but at a slice interspace of 1.0 mm, they were high for most components of the auditory ossicles.
听小骨切片以1.5/1.5毫米（61例患者）、1.0/1.0毫米（13例患者）或1.5/1.0毫米（33例患者）的切片厚度/切片间距进行扫描。在任何类型的切片厚度/间距下，锤骨和砧骨结构的观察频率几乎相等。砧镫关节区域和镫骨的各个组成部分在1.0毫米的切片间距下比在1.5毫米时显示得更频繁。研究了每个听小骨成分在两个或更多连续切片上的可视化频率。在1.5/1.5的切片厚度/切片间距下，除了锤骨头和砧骨体等大的成分外，可视化率较低，但在1.0毫米的切片间距下，大多数听小骨成分的可视化率较高。
