This report quantitatively compares long-term head remolding achieved by two methods for retarding bone reunion after midline craniectomy for sagittal suture synostosis. In one group of six children the adjacent bone edges were overlayed with 1.0-cm-wide U-channel silicone strips, and in the other group, composed of seven patients, a considerably larger extent of the adjacent cranium was covered with silicone sheets. Mean percent change in the cephalic indices of the former group 18 months postoperatively was 9.1% +/- S.D. = 6.7, and of the latter group 23.7% +/- S.D. = 6.0 (p congruent to 0.01). These results indicate that the use of large silicone sheets lead to a significantly greater normalization of cranial proportions.
本报告定量比较了两种方法在矢状缝早闭行中线颅骨切除术后延缓骨愈合所实现的长期头部重塑效果。在一组6名儿童中，相邻骨边缘覆盖1.0厘米宽的U形槽硅胶条，另一组由7名患者组成，相邻颅骨的更大范围覆盖硅胶片。前一组术后18个月头指数的平均百分比变化为9.1%±标准差=6.7，后一组为23.7%±标准差=6.0（p约等于0.01）。这些结果表明，使用大硅胶片可使颅骨比例显著更趋于正常。
