Radiologic evaluation of frontal sinus fractures is instrumental in determining the need for surgery. Computed tomography (CT) is an excellent modality for evaluation of frontal sinus trauma, particularly for anterior and posterior wall fractures. However, fractures of the nasofrontal duct are more difficult to delineate, and judgments about operating for this problem are often made on less than concrete evidence of duct trauma. To evaluate the usefulness of CT in identifying nasofrontal duct trauma, a two-part study was done. First, CT was performed on cadavers to study the anatomic relationship of the nasofrontal duct to midface anatomy. Then, a retrospective study was performed in 19 patients with suspected frontal sinus fractures who underwent frontal sinus surgery. Findings at surgery were compared with preoperative evaluation with CT. Correlations were identified and criteria developed that can be used to identify patients needing surgical intervention in frontal sinus trauma. These criteria include findings of either a fracture involving the base of the frontal sinus or a fracture of the anterior ethmoid complex, or both.
额窦骨折的放射学评估对于确定是否需要手术至关重要。计算机断层扫描(CT)是评估额窦创伤的极佳方式,尤其适用于前壁和后壁骨折。然而,鼻额管骨折更难清晰显示,针对此问题的手术决策往往基于不那么确凿的鼻额管创伤证据。为评估CT在识别鼻额管创伤方面的效用,开展了一项分为两部分的研究。首先,对尸体进行CT检查,以研究鼻额管与面中部解剖结构的解剖关系。然后,对19例疑似额窦骨折并接受额窦手术的患者进行回顾性研究。将手术结果与术前CT评估结果进行比较。确定了相关性并制定了标准,可用于识别额窦创伤中需要手术干预的患者。这些标准包括涉及额窦底部的骨折或前筛窦复合体骨折,或两者皆有的发现。
