影像学检查对鼻骨区骨折的诊断价值

The Value of Imaging Examination In Diagnosing Fractures of Nasal Region

目的:探讨影像学检查对鼻骨区骨折的临床应用价值。材料与方法:在80例鼻区骨折中,对70例单纯性鼻骨骨折患者行x线拍片检査。对10例鼻区复合性骨折患者行HRCT检査,层厚2mm,鼻区靶扫描,骨算法重建成像。结果:80例鼻区骨折中:单纯鼻骨骨折70例占87.5%(鼻骨橫行线样骨折60例,单纯性鼻骨粉碎性骨折10例),鼻骨粉碎性骨折合并面骨的复合性骨折10例占12.5%。其中4例上颌骨额突骨折,3例泪骨骨折和2例眼眶壁骨折,1例上颌骨鼻骨缝分离。结论:鼻骨区骨折是临床常见的损伤性病变,大多数单纯性鼻骨骨折X线平片检查可以明确诊断。鼻骨区复合性骨折常需采用CT或高分辨率CT(HRCT)检査。HRCT检査能细致地显示鼻区部骨结杓,对鼻区复合性骨折的部位丶程度及伴发改变观察全面丶准确,是具有重要临床价值的检査方法。

Purpose： To study the clinical value of Imaging examination in diagnosing fractures of nasal region. Materials and Methods： In 80 cases diagnosing injuries of the nasal region,70 cases with simple fractures of the nasal bonesshown on X-ray films were reviwed. 10 cases with complex fractures of the nasal region shown on HRCT also were revewed.HRCTperformed with slice thickness of 2mm and bone algorithm. Results： In 80 cases with the fractures of nasal region： 70 simple fractures of nasal bone,87. 5%（ 60 cases of transverse fracture of the nasal bones,10 cases of comminuteted fracture of the nasal bones）. In10 complex fractures with the comminuted nasal bones,12. 5% ： fracture of the frontal process of maxillary bone was found in 4 cases,fracture of lacrimal bone in 3 cases and fracture of orbital walls in 2 cases. Separation of nasomaxillary suture was found in 1 case. Conclusion： The fracture of nasal bone is a common injury. The most cases of simple nasal bone coul diagnose with X-films. But complex fractures need HRCT scan. HRCT could accurately display the bony details in the nasal region including location,extent and secondary changes of complex fractures.
