目的：应用HRCT标准化测量儿童内耳正常解剖结构，为无肉眼可视的微小内耳畸形提供诊断依据。方法：对76例正常儿童152耳行颞骨HRCT检查。获得原始图像后行MPR得到测量图层，采用双盲法测量上半规管、外半规管、后半规管的骨管及骨岛的宽度、耳蜗的最大高度和宽度、前庭的最大宽度和长度等，再对各参数行不同年龄、性别及左右耳间的统计学分析。结果：上半规管骨管管腔宽度、骨岛宽度分别为（0.87±0.04）mm、（4.54±0.39）mm；外半规管骨管管腔宽度、骨岛宽度分别为（1.50±0.05）mm、（3.06±0.36）mm；后半规管骨管管腔宽度、骨脚长度分别为（1.12±0.10）mm、（6.17±0.07）mm；耳蜗高度、长度分别为（4.46±0.11）mm、（8.04±0.16）mm；前庭宽度、长度分别为（3.38±0.36）mm、（5.68±0.51）mm。不同年龄、性别及左右耳之间的测量值差异均无统计学意义（均P>0.05）。结论：儿童内耳的正常解剖结构在颞骨HRCT图像上可准确测量，不同年龄、性别及左右耳之间的内耳骨性结构无明显差异。
目的：應用HRCT標準化測量兒童內耳正常解剖結構，為無肉眼可視的微小內耳畸形提供診斷依據。方法：對76例正常兒童152耳行顳骨HRCT檢查。穫得原始圖像後行MPR得到測量圖層，採用雙盲法測量上半規管、外半規管、後半規管的骨管及骨島的寬度、耳蝸的最大高度和寬度、前庭的最大寬度和長度等，再對各參數行不同年齡、性彆及左右耳間的統計學分析。結果：上半規管骨管管腔寬度、骨島寬度分彆為（0.87±0.04）mm、（4.54±0.39）mm；外半規管骨管管腔寬度、骨島寬度分彆為（1.50±0.05）mm、（3.06±0.36）mm；後半規管骨管管腔寬度、骨腳長度分彆為（1.12±0.10）mm、（6.17±0.07）mm；耳蝸高度、長度分彆為（4.46±0.11）mm、（8.04±0.16）mm；前庭寬度、長度分彆為（3.38±0.36）mm、（5.68±0.51）mm。不同年齡、性彆及左右耳之間的測量值差異均無統計學意義（均P>0.05）。結論：兒童內耳的正常解剖結構在顳骨HRCT圖像上可準確測量，不同年齡、性彆及左右耳之間的內耳骨性結構無明顯差異。

Objective:The purpose of this study is to provide diagnostic criteria of indistinctive inner ear malformations by HRCT standardized measurements of normal inner ear structures in children. Methods:76 normal children with 152 ears were underwent HRCT of temporal bone. Image were reconstructed by MPR. Two senior radiologists used the double blind means to measure all the image data,including the width,highness of superior semicircular canal (SSCC),lateral semicircular canal (LSCC), posterior semicircular canal (PSCC) cochlea and vestibule. The differences of the above data between the age,different gender, the left and right ears were compared. Results:Width of SSCC bone tube and bone island were (0.87±0.04)mm and (4.54± 0.39)mm,respectively. Width of LSCC bone tube and bone island were (1.50±0.05)mm and (3.06±0.36)mm respectively, PSCC bone tube width and bone leg length were (1.12±0.10)mm and (6.17±0.07)mm,respectively. Cochlea height and length were (4.46±0.11)mm and (8.04±0.16)mm,respectively. Vestibule width and length were (3.38±0.36)mm and (5.68±0.51)mm, respectively. There were no differences between the age,different gender,the left and right ears (t-test,P<0.05). Conclusions:HRCT standardized measurment of normal inner ear structures in children were obtained. There was no difference between the age,different gender,and the left and right ears.
