多层螺旋CT在儿童后鼻孔先天性闭锁诊断中的应用价值

The value of MSCT in the diagnosis of congenital atresia of posterior nostril in children

目的分析掌握后鼻孔先天性闭锁的多层螺旋CT诊断要点。方法选取9例后鼻孔先天性闭锁的患儿行螺旋CT容积扫描,进行MPR三维重建,总结其影像学特征。结果后鼻孔双侧闭锁4例,后鼻孔单侧闭锁5例,均为右侧;其中混合性闭锁5例,膜性闭锁3例,骨性闭锁1侧。结论多层螺旋CT可以从不同角度显示后鼻孔先天性闭锁的组织结构﹑狭窄程度与周围组织器官的毗邻关系,更好的为临床选择治疗方法提供有力的依据。

Objective To analyze and master the key points of spiral multi-slice CT diagnosis of congenital atresia of posterior nostril.Methods 9 children with congenital atresia of the posterior nostril were selected for spiral CT volume scanning and MPR 3D reconstruction.Results There were 4 cases of bilateral atresia of the posterior nostril and 5 cases of unilateral atresia of the posterior nostril.Conclusions MSCT can show the tissue structure and the degree of stenosis of congenital atresia of the posterior nostril and the adjacent relationship between the degree of stenosis and the surrounding tissues and organs from different angles,which can provide a better basis for clinical treatment.
