Rates of growth of the premaxilla in baboons, which have undergone removal of the nasal septum, and unoperated controls are compared using X-ray cephalometric analysis and direct measures. It is found that our X-ray analysis without the use of metallic implants is not sensitive enough to detect changes of growth rate which are detectable through direct measurement.
通过X射线头颅测量分析和直接测量，比较了已切除鼻中隔的狒狒和未手术对照组的前颌骨生长速率。结果发现，我们不使用金属植入物的X射线分析对检测生长速率变化的敏感度不够，而通过直接测量则可检测到这些变化。
