Disruption of the nasofrontal ostia or ducts is an important factor in the development of immediate and delayed complications following frontal sinus fractures. Thorough evaluation of 50 consecutive patients with frontal sinus injuries caused by blunt trauma revealed several fracture patterns that frequently include injury to the drainage system. Anterior table fractures, even when displaced, do not produce such injuries unless associated with a fracture of the supraorbital rim or nasoethmoidal complex. Combined fractures of the anterior and posterior tables are almost always accompanied by injuries to the orifices. Severity of these injuries is variable but can be predicted from the sinus wall fracture patterns. Although CT scanning is incapable of directly imaging involvement of the ostia or ducts, it will give sufficient information to allow for accurate prediction of disruption of the drainage system.
鼻额窦开口或管道的破坏是额窦骨折后立即和延迟并发症发生发展的一个重要因素。对50例连续因钝性创伤导致额窦损伤的患者进行全面评估后发现了几种骨折类型，这些类型常常包括引流系统损伤。前壁骨折，即使发生移位，除非伴有眶上缘或鼻筛复合体骨折，否则不会造成此类损伤。前后壁联合骨折几乎总是伴有开口处损伤。这些损伤的严重程度各不相同，但可根据窦壁骨折类型进行预测。虽然CT扫描无法直接成像开口或管道是否受累，但它能提供足够信息，以便准确预测引流系统的破坏情况。
