Increasing experience with computed tomographic evaluation of head trauma reveals this radiologic modality to be superior to conventional polytomography in the assessment of certain areas of maxillofacial injury. A comparison of hypocycloidal polytomography and computed tomography in nine patients with fractures of the medial wall of the orbit reveals CT to be superior in localization of the fracture site, delineation of displaced bone fragments, and recognition of herniation of intraorbital contents into the ethmoid labyrinth. Information regarding damage to the nasolacrimal duct and associated intraorbital abnormalities such as the presence and location of hemorrhage and foreign bodies is also available from the CT scan.
对头外伤进行计算机断层扫描评估的经验不断增加，结果显示在评估某些颌面损伤区域时，这种放射学检查方式优于传统的断层摄影术。对9例眼眶内侧壁骨折患者的旋回断层摄影术和计算机断层扫描进行比较发现，在骨折部位的定位、移位骨碎片的描绘以及识别眶内内容物疝入筛窦迷路方面，计算机断层扫描更为优越。计算机断层扫描还能提供有关鼻泪管损伤以及相关眶内异常情况的信息，如出血和异物的存在及位置。
