| 目的 利用多层螺旋CT(multislice CT,MSCT)重组前庭导水管(vestibular aqueduct,VA)15°斜矢状位图像, 探讨径线测量值对大前庭导水管畸形(the large vestibular aqueduct, LVA)的应用价值。方法 标准化处理106例(212耳) 正常人的颞骨MSCT 图像获得前庭水管标准化图像,测量VA中间径大小, 建立99% 医学参考值范围; 对43(85耳)LVA患者VA中间径进行测量, 并与正常值进行统计学分析。结果 不同性别、侧别及各年龄组间VA中间径大小无统计学差异(t=0.252,P>0.05;t=1.573,P>0.05;F=0.089,P>0.05)。VA中间径(0.76±0.15)mm; 99%医学参考值范围:0.41~1.10 mm。LVA 患者VA中间径最大值为3.60mm, 最小值为1.13mm, 与正常组比较有统计学差异(t=7.892,P<0.05)。结论 利用MSCT多平面重组易于获得VA15°斜状位图像;99%正常人VA中间径参考值范围:0.41~1.10 mm;VA中间径大于1.10mm 提示LAV。 |

| Objective To study the feasibility of measuring diameters of the mid section of the vestibular aqueduct back limb on 15°oblique sagittal image reconstructed using multi-slice computed tomography (MSCT)images of temporal bone for detecting large vestibular aqueduct syndrome (LVAS).Methods Temporal bone MSCT images from 106 normal hearing individuals (212 ears)were used to reconstruct a standarized section image of the vestibular aqueduct.The diameters of the mid section of the aqueduct back limb were measured to establish 99% confidence intervals.Images from different age group,male and female individuals and from the left and right sides were measure separately and the results were compared with those from 43 patients with LVAS.Results There was no significant differences of intermediate diameters between male and female,the left and right,and the different age groups(t=0.252,P>0.05;t=1.573,P>0.05;F=0.089,P>0.05).The mid value of the vestibular aqueduct back limb was 0.76±0.15mm;99% confidence intervals:0.41~1.10 mm.The section size of this segment was greater in LVAS patients than in normal individuals(t=7.892,P<0.05).Conclusion The 15°oblique sagittal image was easily gained with the multiple projection reconstruction of MSCT.The 99% confidence intervals:0.41~1.10 mm;The mid value of vestibular aqueduct back limb is greater than 1.10 mm on suggests the diagnosis of LVAS. |
