摘要:

目的利用螺旋CT评价眶部受植区骨量,为眶部种植手术提供影像解剖学参考。方法利用64排螺旋CT对52例带标记点的正常干颅标本眶部受植区进行薄层容积扫描,行眶部多平面图像重建,在该影像上测量各标记点眶骨骨量(长度×宽度),并进行统计学分析。结果右侧眶部以7点方向骨量最充足,平均11.91 mm×8.38 mm;3点方向骨量值最小,平均2.31 mm×1.34 mm。左侧眶部以5点方向骨量最充足,平均12.03 mm×8.56 mm;9点方向骨量值最小,平均2.44 mm×1.29 mm。左右侧眶部对应各点骨量无显著性差异。男女性在眶部同一位置骨量无显著性差异。结论该CT影像解剖学数据对于眶部种植体规格的选择以及种植体植入的位置和方向具有指导意义。

Abstract:

Objective To evaluate the orbital bone quantity by spiral computer tomography(CT) for orbital implant operation. Methods Fifty -two normal skull specimens with marks received spiral CT scan and their multiplanar images were obtained. The quantity (length×width) were measured on multiplanar images. Results The right orbital bone quantity at 7∶00 was the highest, average 11.91 mm×8.38 mm, and at 3∶00 was the lowest, average 2.31 mm×1.34 mm. The left orbital bone quantity at 5:00 was the highest, average 12.03 mm×8.56 mm, and at 9∶00 was the lowest, average 2.44 mm×1.29 mm. There had no significance correlation with gender at the same position in both sides. Conclusion Useful data had been obtained for the selection of the placement sites, direction, length, and diameter of orbital implants.
