摘要
目的测量正常内耳前庭大小和面积,为进一步研究前庭相关疾病提供基础性数据。方法回顾性分析2011年4月至2012年7月在北京同仁医院行颞骨64层螺旋CT检查且符合纳入标准的受检者240例(480耳),并将其按年龄分为4组:儿童组(〈18岁),青年组(≥18岁,〈45岁),中年组(I〉45岁,〈60岁),老年组(i〉60岁)。每组60例,男、女各30例。在Phillips后处理工作站ExtendedBrilliance…Workspace进行图像经标准化处理后测量前庭的大小和面积。采用SSPS17.0统计软件包进行数据处理。左有侧别的比较采用配对样本t检验,左右侧别差异比较无统计学意义时,采用左右侧的均值进行不同性别、年龄组的比较;不同性别间比较采用独立样本t检验,不同年龄组间比较采用单因素方差分析,P〈0.05为差异有统计学意义。结果前庭各测量指标数值及95%可信区间分别为:(1)横轴面:长径(5.89±0.34)、5.22~6.56mm;短径(2.47±0.36)、1.76~3.18mm;面积(13.97±1.71)、10.62~17.32mm2。(2)冠状面:长径(5.10±0.32)、4.47~5.73mm;短径(2.42±0.21)、2.01~2.83mm;面积(11.30±1.33)、8.69~13.91mm2。(3)矢状面:长径(5.274-0.33)、4.62~5.92mm,短径(3.72±0.35)、3.03~4.41mm,面积(13.77±1.55)、10.73~16.81mm2。横轴面、冠状面、矢状面前庭长径、短径及面积在左右侧别间比较差异无统计学意义(t值分别为-1.283、1.171、-1.557、-0.532、-1.797、-1.244、1.479、0.092、0.409,P值均〉0.05),男女性别问比较差异无统计学意义(F值分别为2.067、1.045、1.631、0.758、0.733、4.81、1.082、0.906、0.101,P值均〉0.05),不同组别间比较差异无统计学意义(F值分别为2.072、1.424、1.953、2.448、2.405、2.101、0.279、2.523、1.715,P值均〉0.05);不同方位前庭各测量指标比较差异有统计学意义(F值分别为5.791、16.806、4.521,P值均〈0.05)。结论容积CT结合后处理测量的前庭经线和面积更为精确,可作为判断前庭大小的客观依据。
Objective To measure the size and area of the vestibule of normal inner ear to provide basic data for further study of the vestibule-related diseases. Methods Two hundred forty patients (480 ears) who underwent temporal bone 64 slices CT scans were enrolled in this study from April 2011 to July 2012. These patients were divided into 4 groups, including Child group ( 〈 18 years), Youth group (18--44 years),Adult group (45--59 years), and Elder group (i〉 60 years). The size and area of the vestibules were measured on the muhiplanar reformatted images in post-processing workstation. Results There were no statistically significant differences in the size and area of vestibules in sides, genders and among the different groups ( P 〉 0.05 ) , while there were statistically significant differences of those in different positions ( P 〈 0.05 ). Conclusion The measurements in different planes were as follow : 1 ) In axial plane,the length of vestibule and its 95% confidence interval were (5.89 ± 0. 34 ), 5.22---6. 56 ram, respectively ; the width ( 2. 47 -- 0. 36 ), 1.76--3.18 mm ; the area ( 13.97 ± 1.71 ), 10. 62--17.32 mm2 ; 2) in coronal plane, the length of vestibule and its 95% confidence interval were( 5.10 ±0. 32),4.47-- 5.73 mm, respectively ; the width ( 2.42 ± 0. 21 ), 2. 01--2. 83 ram; the area ( 11.30 ± 1.33 ) , 8.69--13.91 mm2 ;3 )in sagittal plane, the length of vestibule and its 95 % confidence interval were (5.27 ± 0. 33 ), (4. 62--5.92)mm, respectively; the width (3.72± 0. 35 ), (3.03---4.41) ram; the area ( 13.77 ± 1. 55 ), ( 10. 73--16. 81 ) mm2. The volume CT combined with post-processing technology can accurately measure the size and area of the vestibules. The data can provide quantitative basis for diagnosis of the vestibule-related diseases.
