目的探讨鼻骨斜位螺旋CT高分辨薄层扫描(HRCT)在鼻区骨折诊断治疗和司法鉴定中的应用价值。方法回顾性分析205例鼻区骨折患者的临床及CT诊断资料。所有病例均行鼻骨斜位HRCT扫描、多平面重建(MPR)、SSD重建;159例加做横断位HRCT扫描。结果 205例鼻区骨折中单侧鼻骨骨折17例,双侧鼻骨骨折24例,单纯上颌骨额突骨折29例,单纯鼻中隔骨折3例,鼻中隔脱位4例,鼻颌缝分离14例,鼻骨间缝分离11例,鼻泪缝分离5例,鼻泪管骨折1例,泪骨骨折1例,单纯性眶内壁骨折27例,复合性骨折69例。结论鼻骨斜位HRCT扫描是诊断鼻骨骨折首选检查方法,能提高鼻区细微骨折的检出率,对临床诊断治疗及法医学鉴定具有重要价值。
Objective To investigate the value of nasal slice spiral computed tomography (HRCT) in the diagnosis and treatment of forensic fracture and forensic evaluation. Methods A retrospective analysis of 205 cases of nasal fracture in patients with clinical and CT diagnostic data. All patients underwent nasal skull oblique HRCT scan, multiplanar reconstruction (MPR), SSD reconstruction; 159 cases plus cross-sectional HRCT scan. Results In the 205 cases of nasal fracture, 17 cases were unilateral nasal fracture, 24 cases were bilateral nasal fracture, 29 cases were simple maxillary frontal process fracture, 3 cases were simple nasal septum fracture, 4 cases were nasal septal dislocation, 14 cases were nasal and mandibular septum fracture, Separation in 11 cases, nasolacrimal septum in 5 cases, nasolacrimal duct in 1 case, lacrimal bone in 1 case, simple orbital wall in 27 cases, 69 cases of complex fractures. Conclusion Nasal spine HRCT scan is the first choice for the diagnosis of nasal fracture, which can improve the detection rate of minor fracture in the nasal area. It is of great value in clinical diagnosis and forensic identification.
