目的 探讨多排螺旋HRCT及其后处理技术在鼻区骨折中的临床应用价值，提高鼻区骨折诊断的正确率。方法 使用多 排螺旋CT对32例鼻区骨折病例进行薄层高分辨率扫描并进行后处理观察鼻区骨折的情况。结果 32例鼻区骨折患者 中双侧鼻骨骨折16例次，单侧鼻骨骨折9例次，鼻中隔骨折4例次，上颌骨额突骨折9例次，眶壁骨折5例次，额骨鼻 突骨折2例次，筛窦或上颌窦壁骨折3例次，鼻额缝分离2例次。结论 多排螺旋HRCT及其后处理技术对鼻区骨折诊断 价值明显优于常规CT和X线平片，是诊断鼻区骨折的最佳方法。

Objective Study of multi slice spiral HRCT and post-processing technique in fracture of the nasal region in the clinical application value, to improve the accuracy rate of diagnosis ofnasal fracture. Methods Observation of nasal fracture treatment using multi detector row spiral CT in 32 cases of fracture of the nasal region were thin high resolution scanning and post. Results In 32 cases of patients with bilateral fracture of nasal bone fracture in 16 cases,unilateral nasal bone fracture in 9 cases,nasal septum fracture 4 cases,fracture of frontal process of maxilla in 9 cases,5 cases of orbital wall fracture, nasal process of the frontal bone fracture in 2 cases, ethmoid or maxillary sinus wall fracture in 3 cases,nasal volume joint separation in 2 cases. Conclusion Multi slice spiral HRCT and post-processing technique of nasal fracture diagnosisvalue is superior to conventional X-ray and CT,is the best method for diagnosis of nasal fracture.
