摘要
为给临床行枕颈融合内固定术提供解剖学资料,对50 块干燥完整的成人枕鳞下部的厚度进行了测量。结果表明枕鳞下部厚度不均匀,以枕外隆凸处最厚,为11 ～17 mm ,平均14 .3±2 .6 mm ;最薄部位位于枕外隆凸外下方小脑窝处,为1 .2 ～7 .6 mm ,平均2 .5 ±0 .7 mm 。骨质厚度从枕外隆凸起向外向下放射状递减,左、右无明显差异( P> 0 .05) 。同时对枕鳞下部厚度进行了分区和讨论,其中厚度大于8 mm
In order to provide anatomic basis for the fixation of occipito-cervical fusion, the thickness of the inferior part of the squamous portion of the occipital was measured on 50 dry adult skulls. The results indicated that the thickness of the squamous portion of the occipital was uneven, the external occipital protuberance was the thickest place, 14.3±2.6(11～17) mm, while the region of cerebellar fossa was the thinnest, 2.5±0.7(1.2～7.6) mm. The thickness decreased radially from the external occipital protuberance, and there was no significant difference between left and right (P>0.05). The squamous portion of the occipital was divided into different partion according to its thickness. These area which was thicker than 8 mm was the best suitable entry for screw fixation in the operation of occipito-cervical fusion
