The objective of this study is to analyze the biomechanical effects of sinuses in the skull on the facial impact response. Two models were built, where one had sinuses and the other had none. The models were verified using cadaver test data, including impacts to frontal bone, zygomatic bone, and maxillae. In the maxilla and zygoma impact, sinuses were found to have no significant effect on the global distribution of stress or stiffness of facial bones, and the influence was limited in local area. In forehead impact, the sinuses significantly affected the distribution of stress and strain in the skull due to its location in facial bones. The result shows that if the sinus is far away from the location of impact, its effect on the overall response of skull could be ignored. In addition, the distance between the region of interest and sinuses is another important parameter when studying the local effect of sinuses.
本研究的目的是分析颅骨中的鼻窦对面部撞击反应的生物力学影响。构建了两个模型，一个有鼻窦，另一个没有。使用尸体测试数据对模型进行了验证，包括对额骨、颧骨和上颌骨的撞击。在上颌骨和颧骨撞击中，发现鼻窦对面部骨骼应力或刚度的全局分布没有显著影响，且影响局限于局部区域。在额头撞击中，由于鼻窦位于面部骨骼中，它对颅骨中的应力和应变分布有显著影响。结果表明，如果鼻窦远离撞击位置，其对颅骨整体反应的影响可以忽略不计。此外，在研究鼻窦的局部影响时，感兴趣区域与鼻窦之间的距离是另一个重要参数。
