To better understand and observe craniofacial growth, researchers carry out longitudinal cephalometric studies on animals. The authors constructed a cephalostat specially designed to study craniofacial growth in rats. They describe and validate a cephalometric technique using this cephalostat. They carried out cephalometric radiography and analysis of 62 Wistar rats. By using this method, the authors were able to take repeated, reproducible intracranial, intramandibular and craniomandibular measurements of the rats. The proposed method is a useful tool for studying the craniofacial growth process.
为了更好地理解和观察颅面生长，研究人员对动物进行了纵向头颅测量研究。作者专门设计了一个头颅固定架来研究大鼠的颅面生长。他们描述并验证了使用该头颅固定架的一种头颅测量技术。他们对 62 只 Wistar 大鼠进行了头颅 X 线摄影和分析。通过使用这种方法，作者能够对大鼠进行重复、可重现的颅内、下颌内和颅颌测量。所提出的方法是研究颅面生长过程的有用工具。
