目的：探讨内耳的解剖及发育特点,初步建立规范化的内耳多排螺旋 CT (MSCT)测量标准。方法回顾性的对81例正常头颅 MSCT 的原始数据进行内耳区放大重建,利用多层面重建(MPR)实现内耳各测量径线最佳显示后保存图像并测量。各测量值不同侧别间、性别间用 t 检验,不同年龄组间用单因素方差分析,检验水准α=0.05,P <0.05为差异有统计学意义。结果内耳各测量值不同年龄组间、性别间、侧别间的差异均无统计学意义；骨半规管的走行不全都是规则的圆形或椭圆形,管径以后半规管最大,前半规管最小,高度以后半规管最大,水平半规管最小,宽度以前半规管最大,水平半规管最小。结论初步建立了内耳的 MSCT 测量规范；头颅 MSCT 原始数据后处理后可以清晰地显示内耳的主要结构。

Objective To evaluate the anatomical and developmental characteristics of inner ears and establish a normalized inner ear multi-slice computed tomography (MSCT)measurement standard.Methods The raw data of 81 normal head MSCT cases were amplified and reconstructed in inner ear areas and multi-plannar reformation (MPR)was used to measure diameters of the inner ears.-test was used to inspect the difference between sides and genders,one-way analysis of variance was adopted for different age groups. Significance level α=0.05,P <0.05 was considered statistically significant.Results There was no statistical significance in measured values of inner ears in different age groups,genders and sides.Not all the shapes of bony semicircular canals were completely circu-lar or elliptical.In lumen,posterior semicircular canal was maximal and superior semicircular canal was minimal.In height,posterior semicircular canal was maximal and lateral semicircular canal was minimal.In width,superior semicircular canal was maximal and lateral semicircular canal was minimal.Conclusion Measurement specifications of inner ear on MSCT are initial established,main structures of inner ear can be clearly displayed by post-processing of head MSCT raw data.
