鼻骨骨折的X线片与CT的结合性诊断与分析

The Diagnostic Value of X-ray Film and Computed Tomography for Fracture of Nasal Bones

目的:对比X线片和CT检查在鼻骨骨折中的诊断价值,评价分析两者在应用中的优越性。方法:对100例明确鼻骨外伤患者全部行X线片检查,其中73例行CT检查,对比分析其相应的表现及诊断。结果:100例患者中,X线检查示骨折51例,可疑骨折18例,余阴性。CT检查65例示骨折征象,其中单侧鼻骨骨折16例,双侧鼻骨骨折15例(粉碎性骨折12例),单纯性骨缝分离2例,骨折伴骨缝分离8例,复合型鼻骨骨折24例并对鼻区复合伤和周围情况诊断明确;空泡征2例,余阴性。X线阴性但CT发现骨折17例。结论:普通X线片是鼻骨骨折简单初步的检查方法,价廉易于接受,但误诊漏诊率较高。应将CT列为其必备的检查项目,虽诊断明确可靠但费用较前者昂贵,部分患者不易接受。针对不同患者,X线片、CT两种检查可互相补充,CT检查诊断明确,为临床治疗提供直观清晰的图像,较X线片更具优越性。

Objective：To investigate the diagnostic value of X-ray film and computed tomography（CT） for fracture of nasal bones.Methods：100 patients with trauma of nasal bones were included into the study.All patients received X-ray film investigation and 73 patients had CT scan.The original images of 25 patients who ceceived CT scan were reconstructed with three dimensional technique.the all images of 100 patients were analyzed by two radiologist respactively.Results：In 100 patients,51 patients were diagnosed as fracture of nasal bones and the other 18 patients were doubtful for fracture of nasal bones by X-ray film.The CT images of 65 patients showed fracture of nasal bones including one-side fracture（16）,double-side fracture（15）,comminuted fracture（12）,split of bony suture（2）,fracture combined split of bony suture（8） and compound fracture（24）.The images of 2 patients showed vacuole sign.Conclusion：X-ray film and CT plays a valuable role in the diagnosis of fracture of nasal bones and the accuracy rate of CT is higher than X-ray film,but X-ray film was more economical.For suspecting fracture of nasal bones,X-ray film is initiatory investigation method and CT is valuable supplementary means.
