面部外伤骨折中,下颌骨损伤是最常见的,而下颌髁状突骨折据统计,占整个下颌骨折的三分之一,这是由于髁状突颈部骨质薄弱,对外力的抵抗力很小,然而,它的脆弱却反映一个重要的目的,也就是要避免作用于下颌体的外力传到颅中凹底。下颌髁状突和下颌窝之间有特别密切的关系,在非常特殊的解剖生理状态和某些外力传导的个别情况下,下颌髁状突可以不发生骨折而使损伤力向颞下颌窝内传导,下领髁状突穿透下颌窝底而进入颅中凹,引起硬脑膜损伤,这种情况很少见,仅有几位作者在专科文献中报告过类似的病例。
In the case of facial traumatic fracture, mandibular injury is the most common, and mandibular condyle fracture, according to statistics, accounting for one third of the entire mandibular fracture, which is due to the weak bone of the condylar neck, the resistance to external force is very Small, however, its vulnerability reflects an important purpose, that is, to avoid the external forces acting on the mandible spread to the cranial midsole. Mandibular condyle and mandibular fossa have a particularly close relationship between the very special anatomical and physiological conditions and some of the external force conduction in individual cases, the mandibular condyle can not fracture and make the damage to the temporomandibular fossa conduction , Under the collar condyle penetrated the bottom of the jaw and into the skull concave, causing dura membrane damage, this situation is rare, only a few authors in the specialist literature reported a similar case.
