Using radiocephalometric procedures, the authors examined the separate effects of suturectomy, periostectomy, and dural transection on the growing skull in young rabbits. When the coronal suture was surgically removed during normal growth, The freed frontal and parietal bones separated at a significantly accelerated rate. No accelerated separation was found when only the overlying periosteum and aponeurosis were transected. Furthermore, no additional separation was observed when the dura mater and falx cerebri were transected following suturectomy. Analysis of growth at the adjacent frontonasal and anterior lambdoid sutures suggested that the accelerated separation of bones after suturectomy was compensated for by reduced growth at these adjacent sutures. The result of these compensatory actions was that the total length of the skull remained unchanged. This study not only supports earlier observations that sutures grow in response to extrinsic separative forces but, significantly, that the suture tissue itself, rather than the dura or pericranium, acts as a restraint during normal translatory growth.
作者采用放射头颅测量方法，研究了缝骨切除术、骨膜切除术和硬脑膜横断术对幼兔生长中颅骨的单独影响。在正常生长过程中手术切除冠状缝时，游离的额骨和顶骨以显著加速的速度分离。仅横断覆盖其上的骨膜和腱膜时，未发现加速分离。此外，在缝骨切除术后横断硬脑膜和大脑镰时，未观察到额外的分离。对相邻额鼻缝和前枕乳突缝生长的分析表明，缝骨切除术后骨骼加速分离是由这些相邻缝线处生长减少所补偿。这些代偿作用的结果是颅骨总长度保持不变。本研究不仅支持了早期的观察结果，即缝线会因外在分离力而生长，而且重要的是，在正常平移生长过程中，起限制作用的是缝线组织本身，而非硬脑膜或颅骨膜。
