目的探讨 Le Fort 型骨折的 CT 表现及其分型。方法对62例 Le Fort 型骨折患者进行薄层螺旋 CT 扫描和三维重组分析。结果在62例中,Le Fort Ⅰ型10例,Ⅱ型9例,Ⅲ型8例,复合型35例(其中Ⅰ+Ⅱ型18例,Ⅰ+Ⅱ+Ⅲ型7例,Ⅱ+Ⅲ型10例);55例同时...目的探讨 Le Fort 型骨折的 CT 表现及其分型。方法对62例 Le Fort 型骨折患者进行薄层螺旋 CT 扫描和三维重组分析。结果在62例中,Le Fort Ⅰ型10例,Ⅱ型9例,Ⅲ型8例,复合型35例(其中Ⅰ+Ⅱ型18例,Ⅰ+Ⅱ+Ⅲ型7例,Ⅱ+Ⅲ型10例);55例同时伴发颌面部其他骨折。Le Fort 型骨折在二维 CT 上表现为颌面部多发且杂乱的骨折,虽然在发现细小和深部结构的骨折方面优于三维 CT 成像,但难以作出 Le Fort 型骨折的诊断;三维 CT 成像能清晰立体地显示 Le Fort型骨折的整体形状及走向,并可明确作出分型。结论三维 CT 成像是 Le Fort 型骨折最有效的诊断方法,对临床制定治疗方案具有指导意义,但是对细小骨折诊断不如二维 CT。展开更多
