The complex nature of midfacial fractures is a result of the interaction of impact forces and inherent resistance of the facial bones to displacement. Analysis of fractures created in cadavers shows that impact forces angled obliquely to the horizontal craniofacial buttresses cause LeFort III fractures with inferior and posterior displacement of the midface. Forces directed head-on to the buttresses cause LeFort II-I fractures with inferior rotation of the midface around the lower ends of the pterygoid plates. It appears that the point of impact is of lesser importance in creating midfacial fractures than is the angle of impact in relation to the horizontal craniofacial buttresses. This may explain why victims of equal impact forces at the same level on the face suffer widely varying injuries.
面中部骨折的复杂性是冲击力与面骨对移位的固有抵抗力相互作用的结果。对尸体骨折的分析表明，与水平颅面支柱呈斜角的冲击力会导致LeFort III型骨折，伴有面中部向下和向后移位。直接作用于支柱的力会导致LeFort II - I型骨折，面中部围绕翼状板下端向下旋转。与水平颅面支柱相关的冲击力角度相比，撞击点在造成面中部骨折方面似乎不太重要。这或许可以解释为什么面部同一水平受到相同冲击力的受害者会遭受差异极大的损伤。
