目的探讨螺旋CT在儿童副鼻窦支气管炎诊断中的价值。方法采用冠状位及横断位对42例反复发作儿童副鼻窦气管炎患儿行螺旋CT扫描。结果42例支气管炎同时合并副鼻窦炎患儿的反复支气管炎发病率达100%。X线胸片以肺纹模糊显示率相对较高为93%;4岁以下年龄组肺炎样阴影显示率为80%,5～10岁年龄组肺炎样阴影显示率则相对较低,仅为35%;但肺门增浓阴影增加,从24%上升至76%。故年龄越小越易显示肺血管周围浸润阴影和肺炎样阴影;年龄越大越易显示肺门增浓影。螺旋CT扫描均有副鼻窦炎表现,以上颌窦炎为主,占94%;其中还有部分患儿腺样体肥大,占65%;年龄越小,病变越严重。结论螺旋CT是反复发作儿童副鼻窦支气管炎患儿的有效检查方法,对诊疗有重要临床意义。
Objective To investigate the value of spiral CT in the diagnosis of paranasal sinusitis in children. Methods Coronal and transverse dislocation of 42 children with recurrent children with sinusitis children with spiral CT scan. Results The incidence of recurrent bronchitis in children with bronchitis and sinusitis was 100%. X-ray chest lung pattern fuzzy display rate was relatively high 93%; 4 years of age group pneumonia-like shadow showed 80%, 5 to 10 years old group of pneumonia-like shadow showed a relatively low rate of only 35 %; But increased hilar shadow increased from 24% to 76%. Therefore, the younger the more easy to show the infiltration of pulmonary vascular shadow and pneumonia-like shadows; the older the easier to show the hilar enhancement shadow. Spiral CT scan showed sinusitis, maxillary sinusitis accounted for 94%; of which there are some adenoid hypertrophy in children, accounting for 65%; the younger, the more serious lesions. Conclusion Spiral CT is an effective method for children with paranasal sinusitis with recurrent seizures, which has important clinical significance for diagnosis and treatment.
